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 specialists, believing that in this way you can reduce costs and save time. This is true if we are talking about a very deep foundation, for the dismantling of which you will need special equipment.
The main stages of dismantling
The dismantling of the foundation is carried out according to a certain algorithm. At the first stage, a schedule should be drawn up. It should describe the specific method and features of the work. It is important to take care of where the garbage will be taken.
Before starting the manipulation, it is necessary to study safety precautions during such work. The main step is dismantling. It provides for mechanical impact on the structure. When it comes to particularly difficult cases, you should use a cutter with a diamond coating.
Dismantling methods
The dismantling of the foundation can be carried out according to one of several technologies, among them:
- manual;
- using an excavator;
- using an explosion;
- using chemical compounds;
- use of hydrocline;
- the 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, it is best to use heavy equipment or manual techniques. The latter option is the cheapest, but it is labor intensive and is accompanied by the formation of a large number of fragments.
Additional description of some dismantling methods
The dismantling of the foundation for simplification is usually carried out by heavy-duty heavy construction equipment. This method allows you to perform 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 in the work, but its work is accompanied by the consumption of a large amount of electricity. For other buildings, the application of such a technique will not cause harm. With the help of a hydraulic hammer, it will be possible to break any structure of reinforced concrete.
The dismantling of the old foundation can be carried out according to the most modern technology, which involves the use of hydraulic scissors. Their working surface is diamond coated. If desired, the tool can be rented by contacting specialist stores with relevant products. This approach is convenient if the work is one-time. When several major buildings or economic type buildings are to be dismantled, the purchase of special equipment will be the best solution.
Recommendations for working with a strip foundation
Dismantling the strip foundation is easier. 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;
- hammer drill;
- sledgehammer;
- scrap;
- jackhammer.
In addition, 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 those cases when the channels are inside the structure.
Tips for dismantling a monolithic foundation
The most problematic will be the dismantling of the monolithic structure. Even if you use heavy equipment, it can take several days. Among other things, operating mechanisms can be severely worn. It would be more expedient to use explosives. But this method is used only if the building is located away from other buildings. For this purpose, several holes should be drilled in the foundation where the explosive is laid. This method requires the careful calculation, in order to avoid accidents.
Technology of work
The dismantling of the foundation, the price per cube of which you should know before starting work, must be carried out using a certain technology. If you don’t want to do this work yourself, then you will have to pay 1900 rubles for the destruction of a cubic meter of construction. You can use the chemical method yourself. To do this, several holes are pre-drilled in the foundation, where the chemical composition is poured. The base after this must be left for several days. Concrete in the process corrodes to such an extent that it begins to crumble into small parts, which are quite easy to take out of the territory.
Non-explosive destructive mixtures can also be used. The principle of their work is that the granules after mixing with water increase in volume and begin to break concrete from the inside. The substance is also poured into holes drilled previously. After the composition is filled with water and left for some time. Sometimes craftsmen today use a rather ancient method. The technology provides for driving wedges from dry wood into holes in the foundation. They are watered with water, and after the wood begins to swell and tear concrete.
Conclusion
The dismantling of the foundation, the rates for which were mentioned above, can also be carried out with the help of a hydrocline. This equipment is a concrete breaker, which is small in size. The advantage of this technology is the absence of dust and excess noise. The hydrocline acts on the foundation pointwise. It does no harm to surrounding buildings.
In this case, a tensile effect is exerted on the structure. The hydrocline has a working part, which has the form of a spacer frame. Under pressure, a fluid is used to stretch and break the concrete. The hydrocline perfectly destroys concrete structures even indoors, so you can use the technology in those places where you can not lift the equipment.
