Curtain Injection

It is very costly and time-consuming to subsequently seal undergrade structures such as tunnel constructions, underground car parks, residential buildings that are partly provided with basements or extensions against moisture using traditional methods. Curtain injections are an innovative method of installing post-construction sealings. Drill holes are made into the interior structure and polyacrylate gel is injected behind the structure with a pump. The gel forms a curtain directly in the adjacent soil. The gel curtain prevents water and moisture from penetrating and keeps the masonry permanently dry.
