PC® Leakinject Hydrogel 6880 is a specialist sealing, which doesn’t need any additional catalyst to react with water. It’s perfect as a waterstop for the sealing of pressurized or non-pressurized leakages and water penetrations in walls, floors, concrete constructions, masonry, tunnels, sewer pipes. Recommended particularly for moving structural gaps, including in the joints between in each section parts of diaphragm walls. It can also be used to sealing expansion joints.
PC® Leakinject Hydrogel 6880 is a low viscous, single component, hydrophilic, MDI-based injection resin, which doesn’t need the addition of a catalyst. The product reacts with water and forms a flexible, closed cell foam. It can be injected under pressure directly into leaking or dry gaps. In the case of pressurised leaks, it should be applied directly; in the case of dry, unstructured cracks – the material should be applied after wetting the gap. The resin can also be mixed with water in a 1:1 ratio prior to injection in order to speed up the reaction time.
PC® Leakinject Hydrogel 6880 does not separate in contact with bentonite and forms an integral bond with it.
