What are the costs of removing the foundation? If necessary, in these works it is more advisable to seek help from specialists in this field. This approach to business will not only save time, but also reduce costs. If the foundation is of a small area, then it is quite possible that a simple consultation will be enough. If everything is not so simple, then you cannot do without inviting qualified workers. But under any circumstances, dismantling the foundation will not turn out to be an impenetrable rock.

To dismantle a monolithic foundation, it is advisable to use explosives, since heavy equipment will do this for more than one day, and the working mechanisms of the equipment will greatly deteriorate.

Dismantling the foundation: main stages

Although dismantling requires coordinated, precise work of professionals, the work can be done on your own. However, this will require significantly more time and will be much more difficult. The work is performed in the following order:

1. Before starting work, you need to draw up a schedule. It should contain a detailed description of the method.
2. Consider a plan for removing the old foundation, which will turn into construction waste after dismantling.
3. Familiarize yourself with the safety rules when carrying out work.
4. Think over the names and number of mechanisms that will be needed to dismantle.

It is completely natural that any type of dismantling work requires solving issues of varying degrees of complexity. For example, dismantling an old foundation is the most labor-intensive process. It will require a responsible attitude using special tools and specialized equipment.

Dismantling the foundation: methods and tools used

Approximate average cost of foundation dismantling.

The most common foundations are pile and strip type.

In the absence of heavy equipment, dismantling the foundation is carried out manually using special equipment. Although such work will cost much less, it will take much more time. This method is suitable for dismantling a pile foundation.

Hydraulic equipment will be a great help in dismantling the foundation. Although it is characterized by high energy consumption, there will be no harm to surrounding buildings. A hydraulic hammer can easily crush any reinforced concrete structure. Modern methods include hydraulic shears with a diamond coating. All these tools can be rented from specialized companies or stores. This will be the best solution if the work is one-time. If it is necessary to dismantle several capital-type buildings, then it will be more profitable to purchase equipment.

Dismantling the strip foundation

When working with a hammer drill, you must follow safety precautions and wear a special protective mask.

One of the main advantages of a strip foundation is its ease of dismantling. The thickness of the structure usually does not exceed 0.50 m and is suitable for dismantling:

• powerful hammer drill;
• diamond coated cutter;
• sledgehammer;
• jackhammer.

Dismantling may require special equipment only if the structure includes a channel or reinforcement with a diameter of more than 3 cm.

The most difficult part is dismantling a monolithic foundation. Even heavy equipment will do this for more than one day. At the same time, the working mechanisms deteriorate greatly. It is best to use explosives. It is important here that there are no buildings nearby.

The required number of boreholes (holes) are drilled in the foundation. They are loaded with explosives. Most often it is an ammonite. To avoid possible accidents, careful calculation will be required. The best way to dismantle the foundation has not yet been invented. It is easier and cheaper to dismantle a strip foundation, since the consumption of explosives will be lower.

Foundation dismantling technology

To dismantle a strip foundation, you can use special equipment, but only if the structure has thick reinforcement - more than 30 mm in diameter. or channels.

The method and technology for dismantling the base depend on the type of object. If the foundation was intended for a multi-story building (for example, a shopping center with a large area), then in order to dismantle such a foundation, you will need hydraulic equipment that will help complete such a large amount of work in the shortest possible time. In this situation, heavy artillery comes into play:

• excavators;
• hydraulic hammer;
• hydraulic shears on the boom.

In the case where the foundation was intended for a small house, dismantling work is carried out using diamond-coated tools.

In addition, it is possible to dismantle the old foundation of a country house, which is laid to a great depth, using a non-explosive substance. In this case, instead of explosives, a special emulsion is poured into the drilled holes (holes), which expands and penetrates the old concrete, gradually destroying it.

The cost of dismantling the foundation must first be clarified with companies specializing in this: often the help of professionals will be cheaper than doing the work yourself.

When carrying out a plan for dismantling various structures, you must first obtain all permitting documentation. The prepared work plan must be agreed upon and confirmed by experienced specialists, otherwise subsequent documentation will cause a lot of unnecessary hassle.

One of the most difficult aspects of demolishing any building is dismantling the foundation. To completely disassemble it, you will need special equipment and machinery. For each type of structure, there are several dismantling technologies.

They are distinguished by the material from which they are built: brick, rubble, concrete, reinforced concrete, wood. According to the method of installation - monolithic, prefabricated (foundation made of FBS blocks) or prefabricated monolithic.

Basic parsing technologies:

• manually (jackhammer, sledgehammer, crowbar, grinders, etc.);
• hydraulic hammer, hydraulic shears, excavator;
• using corrosive mixtures;
• dynamite detonation;
• ultrasonic waves;
• hydraulic reinforced concrete breaker or hydrocline.

If the base area is small or there is no possibility for equipment to access the building, then dismantling is carried out manually. This work is labor-intensive and time-consuming, and requires the mandatory use of protective equipment. An excavator bucket is used to dismantle the old foundation at the dacha or in the private sector, made of brick. This method is convenient in that all construction waste is immediately loaded into dump trucks.

Monolithic or prefabricated types of structures can be disassembled in several ways. So, for example, in the first case, the strip foundation is dismantled with a hydraulic hammer. The prefabricated block is demolished with an excavator. For reinforced structures, hydraulic shears are used - this attachment easily cuts any reinforcement.

Non-standard methods

Demolition using dynamite is done only if there are no residential buildings nearby. This dismantling technology should only be carried out by professional specialists, as extremely accurate calculations and full compliance with safety precautions are required. Most often, buildings with a monolithic foundation are blown up. The prices for this method are among the highest, but the end result justifies the costs - all the concrete after the explosion turns into small crumbs.

Corrosive liquids will help dismantle the foundation, which is buried deep in the ground. Holes are drilled in the concrete at equal distances and the mixture is poured into them. After a few days it begins to crumble. Technologies based on ultrasonic waves work on the same principle. The destruction of the foundation will take place quietly and safely, but this will require expensive equipment, and accordingly the prices will be high.

Hydraulic reinforced concrete breaker and hydrocline are used for dismantling concrete and reinforced concrete. These unique tools are capable of dismantling any foundation, absolutely safely, without impacts, dust and noise. First, holes are drilled in the concrete, after which reinforced concrete breaker cylinders are manually installed into them. Under the influence of high pressure, the pistons extend, as a result, the concrete begins to collapse into separate parts. The small size of these devices and the principle of their operation make it possible to dismantle foundations not only outside, but also inside residential buildings.

The total price and terms are always calculated individually, according to the following parameters:

• size, depth and type of base;
• his condition;
• location (residential area or vacant lot around, distance from populated area);
• presence of access roads;
• foundation dismantling method (techniques and tools used);
• availability of an electrical network and other communications;
• Is there a place for workers to live?

All these factors significantly affect the price and timing. So, if it is necessary to dismantle a residential building, then you cannot use impact equipment. Vibration can damage the walls of the building, so you will have to resort to more expensive dismantling technologies.

Price table for dismantling foundations:

Some companies offer a discount depending on the size of the work performed. For example, if the total volume is more than 100 m3, then the discount will be 10% of the total amount, 300 m3 - 20%. In the case of huge sizes (2000 m3), the price is set by agreement. Often, large companies immediately include the preparation and removal of construction waste in the cost of dismantling.

You can do the disassembly yourself, especially if the base is small in size (dacha), but it is better to entrust this work to professionals. Moreover, if a new building is erected on the same site. To do this, the territory of the dacha or private property must be absolutely flat and of the same density. If there is a mistake, subsidence will occur, and eventually the entire building will be in danger of deformation or even destruction. You should not contact companies that offer obviously low prices and are little known.

I’ll try point by point and in my own words, so to speak (I’m completely new, please don’t get angry if something happens).

Yes. These people are aware and disturbing them is not a question.

We climbed into the basement, looked, and thought for a long time. There is an opinion that the inside of the basement is most likely lined with brick and plastered. That is, you can’t really see anything from the basement, I’ll still try to take photos with a flashlight (I’m planning a trip there this weekend).

If the documentation contains a brick base, then it should be visible to the naked eye. The inspection is done as follows - walk around the house. look at the base, look for the slightest cracks on it. If the cracks are longitudinal, then perhaps the plaster has simply come off. If they are transverse, then remember in which places.

There is definitely a base and it is plastered (the same type as a layer of mortar interspersed with crushed stone).
I’ll look for cracks/cracks and take pictures of them (if any) and the general plan and details. As I understand it, this will give general information on the condition of the base (and therefore the foundation indirectly).

Take a good camera with a flash (a phone is not good) and take pictures, take pictures, take pictures. Then you post it here and don’t forget to look carefully at the photos yourself. Sometimes some moments are not immediately noticeable but become more clear in the photographs.

I'll try of course, but see above. As I understand it, in order to get to the foundation from the inside it will be necessary to break down the walls of the basement (which is actually not included in the plans yet).

If everything is fine with the foundation and it is intact, then I would demolish the house and the above-ground part of the foundation - the basement. And what I would leave underground. Well, reinforced tape right on it.

This is the part of the whole matter that interests me most at the moment.
How I see all this (I’ll try to explain): there is an old foundation. Options for resolving the issue with a new one:
1. The most likely “reinforced concrete” one, so to speak: still dig out the old foundation (at least where it will intersect with the planned new one) and build a new one in full (as an option suggested by a fellow architect: 1.5m tape down with reinforcement and all the necessary things).
2. Make the foundation of a new house “on top of the old one.” There are already a lot of questions here. In appearance it seems simpler and less costly in terms of money/work. But how to organize all this correctly?
In this case, is there any need for some kind of connection between the new and old foundations? Or will the old foundation be, roughly speaking, a load-bearing layer for the new one? What is the correct way to do this?
Will the tape be already above the ground? Will I need to do any pre-production before actually taping? As I see it, for example: the old foundation is covered from ground level with layers of crushed stone and sand. Next is waterproofing (I would be very grateful for a more detailed description of the pie), formwork/reinforcement and pouring. Is it worth making a tape or is it better to use a slab in this case? In general, there are a lot of questions and options, I would like to finally pick something and have some kind of concept.

If the soil is sandy, then there is almost no frost heaving, but the sand is very susceptible to washing away and the drainage system must be kept in order.

Can you be more specific here too? Do you mean a storm drain/blind area or something in terms of drainage or something like that?

Sorry for the many letters, but this is the case

If you plan to replace or repair the foundation, then it is necessary to dismantle the foundation. In addition, dismantling an old or burnt house usually ends with the destruction of the foundation. To accomplish this task with maximum efficiency, special equipment, construction or manual labor are used. The entire dismantling process is a labor-intensive and difficult task, which only experienced specialists can do.

Types of foundation:

• Columnar or pile - analysis of this type of foundation is carried out using heavy hydraulic equipment. The piles/pillars are pre-stretched and freed from the soil.
• Belt - small in area, which can be destroyed using a hammer, sledgehammer, hammer drill, or diamond disc.
• The most difficult block type - its removal is carried out only using special equipment. If there are no residential buildings nearby, then you can use explosives.

When special equipment is used, the process of destroying the old foundation proceeds quickly and smoothly. The specialists of the First Dacha Company take into account all the nuances of the process and strictly follow safety precautions to avoid negative consequences. The use of modern technologies can reduce work time and reduce costs.

Methods for dismantling the foundation

Method No. 1 Manual dismantling.

For this purpose, a crowbar and the worker's muscles are used. This method of disassembly is only suitable for a brick foundation.

Method No. 2 Dismantling with a jackhammer.

If the entrance to the object is closed or the foundation is small, then it is possible to use a jackhammer. This work requires a lot of physical effort, so it costs more than dismantling using machinery. It is worth noting that we recycle disassembled foundations and transport them in containers from 8 to 20 cubic meters.

Method No. 3 Using an excavator.

If the foundation is made of concrete blocks, then it can be dismantled using an excavator bucket. Concrete blocks are heavy and are placed in the ground in several rows. Using an excavator, the blocks are pulled out and loaded onto a dump truck. Sometimes this method is used to dismantle a brick or strip base. This method requires a trawl to deliver the excavator to the site, which significantly increases the cost of dismantling work. Therefore, it is advisable to use an excavator to carry out a large volume of work or when complex work is being carried out to demolish a house and its foundation.

Method No. 4 Using a hydraulic hammer.

This tool is an attachment to an excavator boom that works like a jackhammer. It is used for crushing concrete or brick when dismantling strip or brick foundations. The loader loads the waste onto a dump truck with its further removal outside the site.

Method No. 5 Non-explosive method of destroying the base.

Holes are drilled in the concrete foundation into which a special mixture is poured. Under its influence, the base turns into crumbs within two to three days. The rest is disassembled manually using a crowbar or sledgehammer. The time frame for dismantling the foundation of a private house is one to two days. It is believed that it is better to carry out such work in the summer due to the dryness of the soil at this time of year. In autumn or spring, the soil is very waterlogged, which complicates the work of equipment and destroys the appearance of the site.

Dismantling and disassembly in stages

Our specialists visit the site to draw up a robot schedule and familiarize themselves with the features of the upcoming disassembly process. In captivity, means and methods are prescribed that will be optimal in a particular situation. We clearly apply the necessary effort and resources when disposing of waste and minimize costs. The team begins dismantling using the chosen method and removes all resulting construction waste. In any case, you can find out about specific installation methods specifically for your facility only after our specialist has visited the site and preliminary inspected the area with the foundation.

The cost of base removal depends on the following factors:

• What equipment will be used in the process and what tools are needed;
• What is the foundation made of?
• Depth and width of the base;
• Base type;
• Is it possible at the site to provide power supplies for tools?

In addition, the remoteness of the object, where it is located, and whether there are residential buildings nearby play a role. The first dacha company offers its services for dismantling foundations of any type using manual labor or special equipment. Contact us now and find out all the details of the work. Our employee will visit the site completely free of charge to carry out calculations and determine the dismantling method. We will carry out the necessary work quickly and at a high professional level and at a competitive price.

When construction is carried out within the city or on another previously built-up area, dismantling work is required before laying the foundation and subsequent construction of the structure.

We offer services for dismantling the underground part of existing buildings (strip, brick or monolithic foundation) in Moscow and the Moscow region.

We offer the following methods for dismantling the foundation:

- Dismantling a strip foundation with a hydraulic hammer, with a special attachment on the excavator boom. It works on the principle of a jackhammer. The hydraulic hammer is capable of crushing brick or concrete. Most often used to dismantle strip foundations.

- Dismantling a concrete foundation with an excavator bucket. In this way, the foundation of concrete blocks is removed, since our special equipment can easily dig up the blocks and load them into a dump truck for transportation.

- Dismantling the foundation with manual jackhammers. We use this method if equipment cannot enter the site or when the foundation is not large in volume (for example, columnar).

Time frame for foundation disassembly

Demolition of the foundation of a private house will take one or two days, subject to availability of equipment.

When may it be necessary to dismantle the old foundation?

As a rule, it is impossible to erect a new building on an old foundation: firstly, the old foundation has worn out over time and has lost its original load-bearing capacity, and secondly, this initial load-bearing capacity is not enough for the future structure. An example is development within the city, when modern multi-storey buildings are erected on the site of former outbuildings. On a suburban plot, too: if the owner has undertaken to build a new cottage, he wants to get something larger and more perfect instead of the old house. Which means it's heavy.

How to dismantle the foundation

The task of dismantling the underground part of the building is to completely clear the site for future development. Process requirements:

• mandatory compliance with norms and standards (GESN46 dated 10/11/2002);
• minimum risk and inconvenience during the demolition of the foundation caused to the owners/residents of buildings located nearby;
• eliminate the risk when performing work on the site itself;
• availability of all necessary equipment and tools;
• duly executed and certified documentation;
• timely removal of waste from the site.

Regardless of the technology used (see below), the dismantling sequence is generally the same:

• the base is crushed into separate fragments;
• the largest fragments are crushed using mobile crushers;
• Construction waste is removed from the site using excavators and transported to a landfill by trucks.

An important point is the preparation of related documents, without which your event will be considered illegal.

We have all the necessary certificates and permits for preliminary cycle work; we prepare the documents ourselves. By concluding an agreement with us, you can forget about such an unpleasant factor as paperwork.

Foundation dismantling technologies

There are several technologies for dismantling the foundation, differing in efficiency, cost and operating conditions:

• manual method. Tool – sledgehammer, hammer drill, diamond cutter, etc. This is a painstaking method, but for private buildings the low cost of dismantling the foundation speaks in its favor. Considering the relatively small area of ​​the structure, the time frame for execution by a team of professionals is not too long;
• crushing concrete with a pneumatic tool - a manual jackhammer or a special attachment for an excavator. The method is not the most expensive and relatively fast, but it is noisy and transmits significant vibrations to the ground;
• diamond drilling. Relatively quiet, safe, efficient, expensive;
• blasting. Explosives are placed in pre-prepared holes. The fastest way, but expensive and dangerous, is practically prohibited within the city;
• hydrocline – destruction by a directed water jet under high pressure. Water is supplied into pre-drilled holes, under pressure it presses on the walls and leads to their cracking. The method is almost silent, there are no vibrations, it can also be used in residential areas. The efficiency is high (a concrete breaker opens concrete up to 4-5 m thick), dismantling is carried out quickly even with a large area of ​​the structure;
• ultrasound. The ultrasonic effect on the thickness is exerted through pre-drilled cavities. The method is quite safe, but expensive due to the need for special equipment;
• chemical method - using aggressive liquids that corrode concrete. Liquids are pumped into special holes in the thickness of the base. The weakened/destroyed concrete is subsequently removed manually or mechanically.

The choice of method depends on the location of the object, the composition of the material and the structure of the foundation:

• dismantling the brick foundation of a private house (especially if it is a non-buried strip base) is technically simple and can be done manually;
• when removing a strip concrete foundation with a large thickness of reinforcement, special equipment may be required (for example, diamond cutting equipment);
• dismantling a monolithic foundation is carried out using heavy equipment and takes a long time: the equipment periodically needs breaks to “rest”. The best way is explosion, but this is only possible if there is a sufficient distance from other structures;
• Concrete and reinforced concrete foundations are most often dismantled either using diamond drilling or using hydrocline technology.

Our expert will get acquainted with the working conditions at your site, its features and advise on the most suitable method for demolishing the old foundation.

Cost of service for dismantling the foundation

When it is necessary to remove the foundation on a site, cost becomes one of the determining factors: after all, you need to save as much money as possible for future development.

The price of foundation dismantling and timing depend on the following factors:

• type of foundation and its design;
• object location;
• depth, foundation size;
• presence of surrounding buildings;
• foundation dismantling technology;
• the condition of the concrete, the degree of its reinforcement.

For foundation dismantling, the price always varies depending on the specific conditions of the work, so all calculations are carried out individually after a specialist conducts an inspection directly on site.

Dismantling the foundation	Cost (rubles/m3)
reinforced concrete foundation (concrete grade up to B20)	from 2,500 rub./cubic. m.
reinforced concrete foundation (concrete grade higher than B20)	from 3,000 rub./cubic. m.
Rubble foundation	from 2,200 rub./cubic. m.
Brick foundation	from 2,000 rub./cubic. m.
Block (FBS) foundation	from 2,200 rub./cubic. m.

Here is an approximate price list for different types of foundation dismantling work (in Moscow):

• the price of dismantling a strip foundation consisting of bricks or blocks, if done manually, is approximately 2 thousand rubles per cubic meter. For example, to disassemble and dispose of a 10 by 10 tape with a height of 1 meter and a width of 30 cm, it will take 24 thousand;
• Diamond drilling costs 25-85 rubles per meter. depending on the channel width. Ultimately, dismantling using diamond cutting technology costs from 4 thousand per cubic meter. To disassemble the foundation of the same house (10 by 10) - up to 48 to 64 thousand. Costs become justified when the thickness of the reinforcing rod is 1.2-1.6 centimeters;
• dismantling weak concrete (up to M250) using a pile driver or pneumatic hammer - from 2.5 thousand per cubic meter. The foundation of the house from our example will cost about 40 thousand;
• concrete M300 and above – 3.5 thousand. The above house is 10 by 10 - 56 thousand.

That is, the cost of destruction with a piledriver is comparable to the cost of diamond drilling. The advantages of the latter are high speed, as well as the absence of shock vibrations, due to which you may have problems with your neighbors in the holiday village.

A safe and quick method of dismantling is a hydrocline. The approximate cost is starting from 5 thousand and up to 400 dollars per cubic meter. Prices vary depending on the region, working conditions, and size of the facility.

Even if you decide to sacrifice your own vacation and health for dismantling with your own hands, you still cannot do without expenses: renting a car for garbage removal, loading and disposal will also require serious expenses.

If you want to save money, effort and your own time, contact us. Our prices are below the Moscow average. After familiarizing yourself with your object, we will be able to quote the cost of its dismantling.
