HydroBloc Microfoam 510 – Water-stop foam, 1K injection foam

HydroBloc Foam Resin 510 is a classic 1K injection foam with high reactivity. The 1K resin is activated with an accelerator (HydroCat 514) and then reacts very quickly with water, while expanding significantly, to form an elastic and dimensionally stable PU foam with fine, largely closed cells that does not shrink during curing.

Typical Applications

Sealing injections; preferably as a rapid water stop for high-pressure flowing water in joints, cracks, crevices, and fissures in civil engineering and tunnel construction, or for the consolidation/stabilization of scree and loose sand.

Processing

HydroBloc Foam Resin 510 should be activated (accelerated) before processing. The amount added depends on the desired reaction time. 1–4% relative to the base resin is generally sufficient. The water-stop foam can thus be easily adapted to all construction requirements. Due to the highly effective activators, the product is very sensitive to contact with water in any form and reacts even with atmospheric humidity. Accelerated (activated) 510 is therefore no longer shelf-stable and should be used promptly.
