"The GWSK-standard self adhesive layer has recieved
special "canals" for the evaporation of moisture."

Save costs and refurbish

Confirmed by the Fraunhofer Institute

The black colour of the WOLFIN membranes increases the pressure below the waterproofing layer and in combination with the diffusion open material the evaporation process of moisture is increased, leaving you a refurbished and dry roof. If you need to refurbish a roof, keep cool and search for the most ecological and economical solution. This method was also confirmed by the Fraunhofer Institute. 

Correct refurbishment plan

Quick dry out through evaporation

With today's technology when refurbishing it is possible to staple the insulation and new waterproofing, even if the lower layers are moist. Depending on the situation, but using WOLFIN roof and waterproofing membranes it is possible to dry out a moist roof within a couple of years. Each refurbishment should be individually calculated and examined. It is only possible to decide if a refurbishment is possible after the examination.
