The dismantling of the foundation may be required in different cases: sometimes, for example, the foundation wears out, and the building becomes dangerous for operation. Some homeowners prefer to use the services of professionals, believing that in this way they can reduce costs and save time. This is true if we are talking about a heavily buried base, for the dismantling of which you will need special equipment.
Key dismantling steps
The dismantling of the foundation is carried out according to a certain algorithm. The first step is to draw up a schedule. It should describe the specific method and features of the work. It is important to take care of where the garbage will be taken out.
Before starting manipulations, it is necessary to study safety precautions during such work. The main step is dismantling. It provides for a mechanical effect on the structure. For particularly difficult cases, a diamond-coated torch should be used.
Methodsdismantling
The dismantling of the foundation can be carried out using one of several technologies, among them:
- manual;
- using an excavator;
- with an explosion;
- using chemical compounds;
- using hydrocline;
- use of ultrasound.
The manual method involves the use of a jackhammer, crowbar, sledgehammer and other devices. But the excavator can be replaced with any other heavy equipment. If the work is carried out on the territory of a private house, then it is best to use heavy equipment or a manual technique. The last option is the cheapest, but it is labor intensive and is accompanied by the formation of a large amount of debris.
Additional description of some dismantling methods
The dismantling of the foundation for simplification is usually carried out with overall heavy construction equipment. This method allows you to complete the work as soon as possible and does not involve physical exertion. If there is no equipment, you can use the manual method, which is ideal for dismantling the pile foundation.
Hydraulic equipment can help with the work, but its work is accompanied by the consumption of a large amount of electricity. Other buildings will not be harmed by this technique. With the help of a hydraulic hammer, it will be possible to break any structure made of reinforced concrete.
The dismantling of the old foundation can be carried out at the mostmodern technology, which involves the use of hydraulic shears. Their working surface has a diamond coating. If desired, the tool can be rented by contacting the specialists of stores with the relevant products. This approach is convenient if the work is one-time. When several capital buildings or utility-type buildings are to be dismantled, the best way out is to purchase special equipment.
Recommendations for working with strip foundations
It is easier to dismantle the strip foundation. This is due to the fact that the thickness of the base in rare cases exceeds 50 cm. For disassembly, it is recommended to use:
- diamond cutter;
- perforator;
- sledgehammer;
- scrap;
- jackhammer.
Additionally, the use of special equipment for the strip foundation will be required only if the structure was built using thick reinforcement, the diameter of which exceeds 30 mm. This also applies to cases where there are channels inside the structure.
Tips for dismantling a monolithic foundation
The most problematic will be the dismantling of the monolithic structure. Even if heavy equipment is used, it may take several days. Among other things, the working mechanisms may be very worn out. It would be better to use explosives. But this method is used only if the building is located at a distance from others.buildings. For this, several holes should be drilled in the foundation, where the explosive is laid. This method requires careful calculation to avoid accidents.
Work technology
The dismantling of the foundation, the price per cube of which you must know before starting work, must be carried out according to a certain technology. If you do not want to perform these works on your own, then you will have to pay 1900 rubles for the destruction of a cubic meter of the structure. You can use the chemical method yourself. To do this, several holes are pre-drilled in the foundation, where the chemical composition is poured. After this, the base must be left for several days. Concrete in the process corrodes to such an extent that it begins to crumble into small pieces that are quite easy to take out of the territory.
You can also apply non-explosive destructive mixtures. The principle of their work is that, after mixing with water, the granules increase in volume and begin to break concrete from the inside. The substance is also poured into pre-drilled holes. After the composition is filled with water and left for a while. Sometimes craftsmen still use a rather ancient method today. The technology involves driving dry wood wedges into holes in the foundation. They are watered, and then the wood begins to swell and break the concrete.
Conclusion
The dismantling of the foundation, the prices for which were mentioned above, can also be carried out using a hydrocline. This equipmentis a betonol, which has a small size. The advantage of this technology is the absence of dust and excess noise. The hydrowedge acts on the foundation pointwise. It does not harm surrounding buildings.
In this case, the structure is subjected to a tensile effect. The hydrowedge has a working part, which has the form of a spacer frame. Under pressure, a fluid is supplied that stretches and breaks the concrete. The hydrowedge perfectly destroys concrete structures even indoors, so the technology can be used in places where it is impossible to bring equipment.
