Dismantling the foundation: methods, milestones and recommendations

Dismantling of the foundation may be required in different cases: sometimes, for example, the base wears out, and the building becomes hazardous 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 really so, if it is a heavily buried base, for the dismantling of which will require special equipment.

Basic stages of dismantling

The foundation is dismantled using a certain algorithm. At the first stage, a schedule should be drawn up. It should describe a specific method and features of the work. It is important to take care of where garbage will be taken.

Before the start of manipulation, it is necessary to study safety techniques during such work. The main stage is dismantling. It provides a mechanical effect on the structure. If you are talking about particularly difficult cases, you should use a cutter with a diamond coating.

Methods of dismantling

Dismantling of the foundation can be carried out according to one of several technologies, among them:

• Manual;
• With the help of an excavator;
• With the help of an explosion;
• With the help of chemical compounds;
• Use of hydrocline;
• Application of ultrasound.

The manual method involves the use of a jackhammer, a crowbar, a sledgehammer and other devices. But the excavator can be replaced by 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 manual techniques. The latter option is the cheapest, however it is labor-intensive and is accompanied by the formation of a large amount of debris.

Additional description of some ways of dismantling

Dismantling the foundation for simplification is usually carried out with overall heavy construction equipment. This method allows you to perform work in the shortest possible time and does not involve physical exertion. If there is no technique, you can use the manual method, which is ideal for dismantling the pile foundation.

Hydraulic equipment can help in the work, but its operation is accompanied by the consumption of a large amount of electricity. Other structures use of this technique will not cause harm. With the help of a hydraulic hammer it will be possible to break any structure from reinforced concrete.

Dismantling of the old foundation can be carried out using the most modern technology, which involves the use of hydraulic shears. Their working surface has a diamond coating. If desired, the tool can be rented by contacting store specialists with the relevant goods. This approach is convenient if the work is one-time. When several capital buildings or buildings of economic type are to be dismantled, the purchase of special equipment will be an optimal solution.

Recommendations for working with a ribbon foundation

Dismantling the basement is easier. This is due to the fact that the thickness of the base in rare cases exceeds 50 cm. For dismantling, it is recommended to use:

• Diamond cutter;
• Perforator;
• Sledgehammer;
• scrap;
• jackhammer.

In addition, the use of special equipment for the ribbon foundation will be required only if the construction was built using thick reinforcement, the diameter of which exceeds 30 mm. This also applies when there are channels in the structure.

Tips for dismantling a monolithic foundation

The most problematic is the dismantling of the monolithic structure. Even if you use heavy equipment, it can take several days. Among other things, working mechanisms can be very worn out. It would be more expedient to use explosives. But this method is used only if the building is located away from other buildings. In the foundation for this, drill several holes, where the explosive is laid. This method requires a careful calculation, in order to avoid accidents.

Technology of work

Dismantling of the foundation, the price per cube of which you must be aware of before starting work, must be carried out according to a certain technology. If you do not want to do the work yourself, then you will have to pay 1900 rubles for the destruction of the cubic meter of the structure. Self-use can be a chemical method. To do this, in the foundation, several holes are pre-drilled, where the chemical composition is poured. The foundation should then be left for a few days. Concrete in the process is corroded to such an extent that it begins to crumble into small parts, which it is quite easy to take out of the territory.

You can apply and non-explosive destructive mixtures. The principle of their work is that the granules after mixing with water increase in volume and begin to break the concrete from the inside. The substance also falls into the holes drilled preliminarily. After the composition is filled with water and left for a while. Sometimes craftsmen and today use a rather ancient way. The technology provides for clogging in the holes in the foundation wedges of dry wood. They are watered with water, and afterwards the wood begins to swell and tear the concrete.

Conclusion

The dismantling of the basement, the rates for which were mentioned above, can also be carried out with the help of hydrocoline. This equipment is a concrete, which has small dimensions. The advantage of this technology is the absence of dust and excessive noise. Gidroklin affects the foundation pointwise. It does not harm the surrounding buildings.

The construction in this case is a stretching effect. Gidroklin has a working part, which has the form of a spacer frame. Under pressure, a liquid is applied that stretches and breaks the concrete. Gidroklin perfectly destroys concrete structures even inside the premises, so you can use technology in places where you can not bring equipment.
