PU Injection Foam Resins
WEBAC® B15
- Classic Line
WEBAC® 155
WEBAC 155 is a moisture-curing, 1C polyurethane (PU) injection resin that is ready for immediate use without mixing or a catalyst. Upon contact with water, it reacts to form an elastic, surface-tight foam that reliably and permanently seals cracks and cavities/voids. This makes WEBAC 155 particularly suitable for crack injection, masonry waterproofing, and building waterproofing, even against rising water.
