Foundation disassembly may be required in differentcases: sometimes, for example, the foundation wears out and the building becomes dangerous for use. Some homeowners prefer to use the services of specialists, believing that 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 byspecific 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 out.
Before starting the manipulations, it is necessary to examinesafety during such work. The main stage is dismantling. It provides a mechanical effect on the structure. If we are talking about particularly difficult cases, you should use a diamond-coated cutter.
Dismantling methods
Dismantling of the foundation can be carried out on one of several technologies, among them:
- manual;
- using an excavator;
- by explosion;
- using chemical formulations;
- the use of hydroclin;
- use of ultrasound.
Manual mode involves the use ofjackhammer, scrap, sledgehammer and other devices. But the excavator can be replaced with any other heavy machinery. If the work is carried out on the territory of a private house, then it is best to use heavy machinery or manual techniques. 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 methods of dismantling
Dismantling the foundation to simplify usuallyIt is carried out by dimensional heavy construction equipment. This method allows you to perform the work as soon as possible and does not include physical exertion. If there is no equipment, you can use the manual method, which is ideal for dismantling the pile foundation.
В работах может помочь гидравлическое equipment, but his work is accompanied by the consumption of large amounts of electricity. Other structures will not harm this technique. Using a hydraulic hammer, you can break any structure of reinforced concrete.
Dismantling of the old foundation can be done bymost modern technology that involves the use of hydraulic shears. Their work surface has a diamond coating. If desired, the tool can be rented by contacting specialists of stores with relevant goods. This approach is convenient if the work is a one-time. When several major buildings or buildings of an economic type are to be dismantled, the acquisition of special equipment will be the best way out.
Recommendations for working with strip foundations
Dismantling the strip foundation is easier to implement. This is due to the fact that the base thickness in rare cases exceeds 50 cm. It is recommended to use for disassembly:
- diamond cutter;
- perforator;
- sledge hammer;
- scrap;
- jackhammer.
Additionally use specialequipment for strip footing is required only if the structure is lined up using thick reinforcement with a diameter greater than 30 mm. This also applies to those cases when channel bars are located inside the structure.
Tips for dismantling a monolithic foundation
The most problematic will be the dismantling of monolithicdesigns. Even if you use heavy machinery, it can take several days. Among other things, the working mechanisms can be badly worn. It would be more appropriate to use explosives. But this method is used only if the building is located at a distance from other buildings. In the foundation for this, several holes should be drilled where the explosive is laid. This method involves the need for careful calculation, in order to avoid accidents.
Technology of work
Dismantling the foundation, the price per cube of which youmust be known before the start of work, must be carried out according to 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 your own chemical method. To do this, several holes are pre-drilled in the foundation where the chemical composition is poured. Reason after that must be left for a few days. Concrete in the process is eroded to such an extent that it begins to crumble into small pieces, which are quite easy to take out of the territory.
You can apply and non-explosive destructive mixture.The principle of their work is that the granules, after mixing with water, increase in volume and begin to break down the concrete from the inside. The substance is also poured into holes, pre-drilled. After the composition is filled with water and left for some time. Sometimes craftsmen today use a rather ancient method. The technology involves plugging wedges made of dry wood into the holes in the foundation. They are poured over with water, and after the wood begins to swell and break the concrete.
Conclusion
Dismantling of the foundation, the rates for which werementioned above, can also be carried out using hydroclin. This equipment is a breaker, which has a small size. The advantage of this technology is the absence of dust and noise. Hydrocline affects the foundation of a point. It does not harm the surrounding buildings.
The design in this case istensile effect. Hydrocline has a working part, which has the form of a spacer. Under pressure, a liquid is supplied that stretches and breaks the concrete. Hydrocline perfectly destroys concrete structures, even indoors, so you can use the technology in places where you can not bring equipment.
