WEBAC_® 250: injection gel for sealing surfaces in masonry and for dpc

Within the group of WEBAC injection gels, the elastic, very low viscosity polyacrylate gel WEBAC_® 250 is suitable for sealing surfaces in masonry. The gel can also be used for installing a post-construction damp-proof course in masonry. Masonry sealants based on this acrylate gel effectively prevent the penetration of moisture rising from the soil into the structure and its capillary rise here. WEBAC_® 250 has excellent mechanical properties. Its extremely low (water-like) viscosity ensures very high penetration into mineral substrates. 
 

'Neue Wache' in Berlin: sealing of masonry with polyacrylate gel WEBAC_® 250

The 'Neue Wache' in Berlin is one the most significant buildings of Classicism. Rising moisture had severely damaged the building constructed back in 1818. Within the framework of a five-month restoration project the injection gel WEBAC_® 250 was used for installing a dpc in masonry. The gel was injected into the extremely thick walls by means of special drills. The engineers also used a WEBAC product for sealing the building's floor: the bituminous acrylate dispersion WEBAC_® 5611.
