The base for any house is basis. Continuous footing - the most demanded in private construction. It belongs to the monolithic bases, it can build to any owner of the construction site such.
Instruction
1. Depth of continuous footing needs to be determined on soil type. It is important to know, the uniform soil on the site or not. On the area with the non-uniform soil, there is threat of change of all house. That is in this place depth of the base has to be much deeper, to 90-120 cm. Continuous footing with the expanded basis will be suitable for such area. It will help to lower load of the soil.
2. What does construction of the base begin with? Initially execute its marking on the site. Prepare armature, thick fishing line. Hammer rods on perimeter, pull fishing line. From the inside of the turned-out perimeter pull fishing line again. The set fenced place will be future trench under the base.
3. Dig out trench of certain depth, having considered structure of the soil. On its bottom distribute gravel in 15-20 cm of height. His Zatrambuyte, at the same time water. Thus, have prepared pillow for future continuous footing.
4. Further establish timbering. It can be made of boards and nails. Establish boards, fasten with the prepared plates by means of nails and the hammer. For ease of dismantling subsequently and non-receipt of defects in the base, you make fastening from the inside.
5. In the prepared timbering it is necessary to lay armature. It will stiffen design. Previously tie armature with lashing wire or use welding. The binding is considered the best choice since in case of earthquake or the movement of soil welding reduces physical qualities of design.
6. Stack armature so that it had space from surface on 5-8 cm. Length of each cell from armature of 30-35 cm.
7. Before beginning filling of continuous footing, define where there will take place communications. You will expose asbestos-cement pipes for ventilation and water supply system. In advance fill them with sand that solution has not hammered interior.
8. Finishing work, solution filling. Surely think over waterproofing question. It is necessary for prevention of fungus. It is possible to use roofing material, or use new materials. The penetron, additive for concrete solution, completely does it impenetrable for moisture.
9. It is desirable to flood the base for once, it is possible to use the mixer. If necessary stamp solution not to receive downdraughts. Dismantling of wood form for the base can be carried out in 2-3 weeks.
