Our Process
01
We’ll start with a free, no-obligation site visit to check out the cracks, sinking, or movement you’re seeing. You don’t need to prep anything - just show us where the problem is.
02
After the inspection, we’ll email you a clear quote with everything included - no hidden fees. You’ll know exactly what’s needed and how long it’ll take.
03
Once you give us the go-ahead, we carry out a full on-site assessment using laser levels and digital mapping. We confirm slab movement, voids, and soil behaviour - so the right fix is done the first time, without extra back-and-forth.
04
We inject high-strength structural resin beneath the affected areas. It expands and hardens quickly, lifting slabs and re-supporting your home without digging. Clean, fast, and often completed in just one day.
