Bubble drainage board made of high-density polyethylene is used to protect the curtain walls from water and moisture, and the foundation insulation from the mechanical effects of the soil. During construction, earth filling creates an air gap, protecting the foundation curtain walls and foundation insulation from various damages, including the uneven distribution of the pressure load of the spilled soil layer, which leads to additional thermal insulation. At the same time, the special bubble structure of the slab ensures that the groundwater is drained away from the foundation.
