Big distribution was received today by continuous footing. It well is suitable for buildings which have heavy walls and overlappings. It is possible build it independently.
Instruction
1. It is not recommended to build continuous footing on the puchinisty deep-freezing-through soil. These actions will economically not be justified as the volume of land works will strongly increase. Continuous footings from rubblework enjoy wide popularity. They can have various width.
2. When laying the first row it is necessary to apply stone or brick. It is necessary to stack it so that there was no emptiness left at all. It is recommended to apply heater to that part of the base which will be in the earth also. The rubble base in trench with vertical walls can be arranged without timbering. In this case it is necessary to close only sidewalls of trench pieces of roofing felt or roofing material. Material will prevent soil fall. In open trenches which are made in clayey grounds the timbering has to be surely established. It can be moved down and across.
3. The continuous butobetonny footing is very reliable and durable. In the form of filler you can apply crushed stone, gravel, brick fight, etc. The trench bottom under the base has to be stamped. The first layers of laying are recommended to be stacked on five-centimetric layer of solution. After that layers filler keeps within. The layer has to have thickness about 20 cm.
4. If the enforced break in concreting is taken, then the top number of stones needs to be filled in with concrete only on half of their height. Consider, solution has to be plastic. In it without ramming stones have to utaplivatsya. At hot weather butobeton it is necessary to water. The fact is that badly transfers drought. Also you can cover it with bast mats.
5. Continuous footing represents continuous wall which is evenly loaded by the overlying bearing or self-supported walls or columns of framework.
