What is (PU) Grouting?

Polyurethane Injection grouting is a waterproofing technique that involves creating a polyurethane mixture whereby when this mixture is inserted with pressure into the cracks of a structure, the mixture will react and in turn expand and toughen. It is used to stop water flowing through structural joints and cracks.

PU grouting is mainly used to restore cracks and repair water damages that have been done to walls, flooring, etc. It prevents cracks from leaking continuously and it is used to maintain the structure’s operational integrity.

PU Grouting Process

Hole is drilled through the surface on a wall / floor / ceiling

Grout is injected

Grout expands to fill the crack

Hole is covered and sealed

When do you need PU Grouting?

Deep holes in a wall

Cracks in concrete floors, basements, swimming pools, side walls, sewer lines etc.

When you see leakages flowing through cracks or even honeycombed concrete voids

Water damages that can be seen in a wall that is damp

Why do PU Grouting?

Great waterproofing solution for cracks

Fast and efficient repair solution

No noise pollution associated with this type of service

No need for tile reconstruction or breaking

Reinstates the strength of the structure

Strong anti-decay solution that is non-toxic
