Sticking doors and windows

When a foundation moves, it can distort door and window frames, causing them to jam or not close properly. You might also notice new gaps have appeared.

Subsidence caused by clay shrinkage

During long dry spells, clay-rich soils can shrink and pull away from your foundation, causing it to settle. This is a leading cause of subsidence.

Problems from leaking drains or poor ground

Water from broken pipes can wash away soil, creating voids beneath your home. Alternatively, the ground may have been poorly compacted when your home was originally built.

What is subsidence?

When the ground beneath your home is no longer stable and begins to sink, this is known as subsidence. This downward movement directly affects your property’s foundations, causing parts of the structure to shift and leading to significant structural problems.

Common signs include new diagonal cracks (often wider at the top), sticking doors or windows, and rippling wallpaper. While these are strong indicators, the only way to know for certain is with a professional assessment. We can help with an initial, no-obligation consultation to evaluate the signs.

Our solution is a highly engineered geopolymer resin. When injected into the ground, it expands with controlled force and hardens in minutes to improve the soil's strength. Once cured, the material is inert, stable, and environmentally neutral, meaning it won't release any harmful substances into the ground.

Traditional underpinning is like open-heart surgery, requiring major excavation, concrete, and weeks of disruption. Our solution is like keyhole surgery. We inject our material through small tubes, with no need to dig up your garden or move out. It’s faster, cleaner, and far less stressful.

The cost varies depending on the scale of the problem and your property type. However, because our process avoids major excavation and is completed much faster than traditional methods, it is often a more cost-effective solution overall. We provide a detailed, no-obligation quote after a thorough assessment.

Absolutely not. Our process is designed for your convenience. The work is quiet, clean, and our teams are highly professional. You and your family can stay at home and continue your daily routine without interruption.

Most residential projects are completed in just one or two days. The ground is strengthened almost immediately as our material cures to 90% of its full strength in about 15 minutes.

Yes. We have complete confidence in our engineered solutions. All our work on residential properties is backed by a 10-year, insurance-backed guarantee for your long-term peace of mind.
