Clear Out Sublevel Shale with
Gibson's Shale Removals
Discover how our expert shale removal services can prepare your property for safe, stable, and long-lasting new flooring.
The Hidden Danger
Is your floor growing?
Many homes built between the 1940s and 1970s were constructed using colliery shale as a sub-floor filler. When this material gets damp, it undergoes a chemical reaction called “Sulphate Attack.”
This causes the shale to expand (heave), literally pushing your concrete floors upward. This leads to unsightly floor bulges, cracked walls, and doors that no longer shut.
Ignoring the problem leads to structural risk. It requires professional excavation and replacement.
