Pressure Grouting
Wales' Leading Pressure Grouting Specialists
Void Filling & Structural Strengthening Below Ground
Pressure grouting is a key part of our work at Gwynedd Grouting. It involves injecting fluid grout under pressure to fill voids, stabilise ground, seal leaking structures or reinforce masonry. Whether used on its own or in combination with pressure pointing, it’s a highly effective way to restore integrity to ageing or damaged infrastructure.
We use both mechanical worm pumps and piston pumps, depending on the type of grout and the requirements of the job.
Our Pressure Grouting Services
We tailor each pressure grouting project based on depth, access, and the surrounding materials. Applications include:
Void Filling
We inject grout into disused pipes, tanks, or underground voids to stabilise ground and eliminate hidden risks.
Retaining Wall Reinforcement
Used in combination with pressure pointing, pressure grouting strengthens walls by penetrating deeper into the structure.
Leak Sealing
We seal cracks and joints in concrete structures such as culverts, tunnels or reservoirs to stop water ingress.
Soil Stabilisation
Pressure grouting is used to bind and strengthen loose soils, reducing movement and increasing bearing capacity.
