WISKO has been a leading name in the application of flexible waterproofing membranes in underground construction since its establishment in 1987. Our founder, Peter Strasser, has been involved in the industry since 1969, when he worked as a young engineer for a company that won a bid to apply a PVC membrane on a subway station in Vienna, Austria.

The success of this pioneering waterproofing membrane application led Mr. Strasser to remain in the industry, and he eventually established WISKO in 1987. With the owner’s decades of experience in membrane waterproofing, the name WISKO has become well-known in the international underground construction industry.
