WestWood® Drainage System

Brief description

The Weplus Vapour Release System is based on the Weplus 251 Vapour Release Mesh and high-quality WestWood PMMA resins. It is specifically designed for the refurbishment of mineral substrates. The system offers a reliable method for removing the moisture enclosed in the substrate by means of a cavity system. Since they are applied as a liquid, the system components create a seamless waterproofing layer that can safely integrate even the most complex details. The system is also weather-resistant, crack-bridging, flexible at low temperatures and its surface can be finished in any desired colour.

Areas of application

The Weplus Vapour Release System is applied to mineral substrates. It is used to avoid problems associated with vapour pressure and moisture, such as blistering or osmotic damage in the surfacing / waterproofing. Complete removal of the existing mineral substructure can be avoided. The load-bearing system is used predominantly for balconies and terraces.
