A void doesn't happen overnight, and you usually can't see it coming until the slab starts to sink.

Understanding what causes it (water, poor compaction, or both) helps explain why the same problem tends to come back if the underlying cause isn't fixed.

A large workshop slab, and the ground beneath it simply wasn’t there anymore.

Catastrophic rain had washed out the soil underneath the slab, leaving voids where solid support used to be. What looked fine on the surface was hollow underneath, and it was only a matter of time before that caught up with the structure.

To correct it, we carried out void fill, lifting and supporting the slab back to within 3mm of level.

The result: every void filled, with complete re-engagement of the subsurface to the underside of the slab and the drop edge beam footings.

Even the heaviest rain leaves its mark where you least expect it.

A sticking door gets blamed on the weather more than anything else.

Sometimes that's true. But if it's happening across multiple doors or windows, or it's getting worse instead of better, your foundation is probably the real cause.

A traditional Victorian home, its chimney slowly pulling away from the structure.

The chimney area had subsided, with cracking showing up both internally and externally, and the brick wall had started bowing outward. The cause came down to a combination of factors, the sheer weight of the chimney, a neighbouring sewer line running nearby, and reactive clay soil beneath the home.

To correct it, we set up formwork props to encourage the structure to rotate back inward, then carried out injection at multiple depths to lift and compact the soil underneath.

The result: 15mm of lift, strong rotation back into place, and a real improvement to the bow in the brick wall.

Old homes carry character, and sometimes a little extra weight to manage too.

This is one of the most common questions we get, and a fair one to ask before spending money on a fix.

Resin injection isn't a stopgap. Once it cures, it becomes a stable structural support that holds as long as the underlying cause of movement has been properly addressed.

We're not saying rip out every tree near your house.

But if you've got established trees close to your foundation and you're noticing movement, the roots are worth a look. It's one of the most overlooked causes of settling.

A front corner. A small access point. A big difference underneath.

This house had cracking and displacement in the brickwork on a front corner, right in the subfloor area, caused by very shallow footings and subsidence that had built up over time.

To correct it, we carried out keyhole resin injection at and around the brick substructure, reaching varying depths to support exactly where it was needed most.

The result: another great job in the books. An easy, fast, and safe lift, with the ground conditions improved enough to properly support the structure and help prevent any further movement.

Small access, solid results.

An entire factory floor, shifting in sync with the walls around it. Here’s what caused it.

This factory complex wasn’t dealing with a single crack or one weak spot, it was widespread movement and misalignment across the tilt panel common walls and slab floors, affecting the structure as a whole.

The cause came down to the ground itself. Poor soil conditions beneath fairly shallow footings had allowed subsidence to build up gradually over time, pulling walls and floors out of alignment as the support beneath them weakened.

To correct it, we carried out multi-staged resin injection at every required location and varying depth, working to raise and relevel the footings, walls, and floor slabs together rather than treating them as separate problems. For the internal slabs specifically, we switched to our proprietary roadbase resin, built to lift and support large floor areas under real operational load.

The result: strong, consistent lift along the rear and common walls and footings, with ground conditions vastly improved throughout the complex. The internal floor slabs were relevelled to provide a flat, safe work floor for the businesses operating inside.

Commercial structures move too, and the fix has to match the scale of the problem.

These signs are easy to explain away individually.

A door that sticks in summer, a crack you patch and forget. But when a few of these show up together, it's usually your foundation, not bad luck.

A crack in the brickwork isn't where the story starts. It's where it finally shows.

On this property, cracking and movement in the external brickwork pointed to something happening well below the surface, water ingress under the footings, and poor soil conditions quietly weakening the ground beneath the home.

We carried out resin injection at key locations and varying depths, working to lift and stabilise the footings while a structural prop supported the structure throughout the process.

It's proof that the right support at the right depth makes all the difference. The result: a good lift, solid support beneath the structure, and some very positive crack closure.

If your brickwork is cracking, it's worth finding out what's happening underneath before it spreads further.
