PU Combi Injection Resins
PU combi injection resins are polyurethane-based hybrid products that combine polyurethane foam resins (SPU) and PU resins. They combine the properties of a fine-celled, waterproof foam when in contact with moisture and a flexible, non-foaming material in dry areas. They are particularly suitable for specialized applications such as crack injections and damp proof courses in large cavities/voids and areas with standing water. Thanks to the combination of SPUR and PU resin, the foam displaces water and seals voids/cavities, while the PU resin ensures a durable and stable seal.

WEBAC 1500 is a CE-certified PU combi injection resin that combines the beneficial properties of PU foam resins and PU resins. Upon contact with water, it rapidly forms a dense, elastic foam that ensures a permanent seal, but it also cures with constant volume even without water. It is particularly suitable for sealing cracks, cavities, voids, and areas exposed to water.

WEBAC® 155
- Classic Line
View detailsWEBAC 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.
