Carrying out construction of the house with the basement, you will need to pressurize it to prevent penetration into the basement of water. Councils how to provide tightness, will help you to create independently completely isolated base and the basement of the building.
Instruction
1. Being going to build the operated basement, previously study recommendations how to provide tightness of the base of the building under construction, and then select optimum construction method. Think of waterproofing of the basement in advance, holding the next establishing events at stage of construction of the base of your house. First, use special plates of walls, reliable base slabs and plastic feature connectors which are strengthened by polyethylene layer for construction of your base.
2. Cast the base from concrete and lay on it element from polyethylene, then mount wallboards on the basis. Weld on them political ethylene waterproofing which provides absolute water tightness and vapor impermeability. At the final stage reliably weld polyethylene elements and base slabs among themselves.
3. Hold protective measures for the designs located below grade level. Counting expected loading from water, surely consider level of underground water and also the maximum level of water lifting during possible floods that subsequently the basement of your building could be operated without any hindrances all the year round. At design of the basement increase design load as this measure will allow you not to hope for reliability of dams, construction of dams or melioration of territories near which you build the house.
4. To provide tightness of the base, isolate structure of the base of your house from possible contact with soil, creating integral hermetic insulation layer without gaps. Carefully work special sealants all "dangerous zones" of the base and the basement located below grade level, reliably closing up seams, corners and knots of adjunction of walls and various designs. Consider the increased risk of clinking in places where diverse surfaces are interfaced, and you apply multilayered elastic protection which will not crack under the influence of external factors on seams and joints.
5. In already ready building you can create the hermetic base, using the melted bitumen or more convenient pressurizing tape in application and special mastic. For this purpose directly on seams apply mastic on external and internal part of the base with the palette, it is not dependent on how the surface – dry or wet looks, and then accurately paste from above the pressurizing tape.
