7.10. Foundation waterproofing
In the course project adopted the following form of waterproofing – waterproofing coating. Painting is done by applying bituminous mastics to the surface to be painted.The number of applied layers is 2. Waterproofing is carried out in accordance with E4-3- 184.
For the strip foundation:
To calculate the amount of work necessary to find the surface waterproofing area.
𝑆𝑤𝑎𝑡𝑒𝑟𝑝𝑟𝑜𝑜𝑓 =[(ℎ𝑓 (𝑠) ∙ Рexterior walls) + ((0,25 + 0,3) ∙ Рexterior walls)] ∙ 2, 𝑚2
where, ℎ𝑓 (𝑠)– the height of the structure basement, ref monolithic strip foundation section (figure.3);
Рexterior walls– perimeter of the exterior walls of the building.
For the columnar foundation:
𝑆𝑤𝑎𝑡𝑒𝑟𝑝𝑟𝑜𝑜𝑓=[(0,3 ∙ 1,6) ∙ 4 +
(0,9 ∙ 0,9) ∙ 4) + ((1,6 ∙ 1,6) − (0,9 ∙
0,9))] ∙ 𝑎 ∙ 2, 𝑚2
where, 𝑎– number of foundations in the plan (per the scheme).
