t is an insulation system that protects the curtain walls against earth water and moisture in the soil. Waterproofing is made with covering types such as sliding based (Bitumen + powder) and membrane (Bituminous, Pvc, Epdm, Tpo).
İf there are bundling membranes from the foundation, the curtain must be combined with waterproofing. In curtain insulations, sliding-based materials should be preferred since they do not leave spaces between seamless and concrete.
Spread based materials should be resistant to alkalis in the soil. After the waterproofing is finished, it is necessary to use thermal insulation (XPS) and drainage plate as a protective layer to protect the excavation from damage.
