Application



PU injection foam resin WEBAC® 150: stopping water when repairing cracks

The fast foam WEBAC® 150 is used for fast and temporarily stopping water when repairing cracks. Injection foam resins are characterized by their strong increase in volume. This is why fast foam can also be used in case of highly pressing water. The 2C foam WEBAC® 150 is thus also suitable for use in dam building, tunnel construction, bridge building and special civil engineering. 
 

Injection foam resin WEBAC® 150: resistant to substances detrimental to the building structure

The fast foam resin WEBAC® 150 is compatible with concrete, steel, masonry mortar, foil and cable sheathing. WEBAC PU fast foam resins are resistant to lyes, acids and salts detrimental to the building structure if their concentration usually found in building structures is not exceeded. To ensure permanent sealing of cracks, a secondary injection with PU injection resins is carried out.
