Geopolymer injection system puts bungalow back on a firm footing


URETEK'S DEEP Injection ground stabilisation system, which uses a geopolymer to increase soil bearing capacity, can now be used to treat ground down to 6m. Previously it could only reach 4m.

The improved system has been used to treat ground beneath a bungalow built on 6m of fill in Upholland, Lancashire. The back of the house sits near the crest of a steep slope, possibly the remains of an 18th century stone quarry.

The bungalow had settled by about 100mm along the rear right corner, resulting in cracks in both internal and external walls.

To stabilise the foundations and prevent further settlement, Uretek injected geopolymer at 1m intervals around the external perimeter of the house in pairs of injection groups at 6m, 5m, 4m, 3m, 2m and 1m.

Uretek also carried out deep injection beneath the interior and exterior walls from inside the house.

Now stabilised, the bungalow's superstructure is being repaired with stainless steel helical reinforcement bars, minor rebuilding works, plaster, floorboards and ceiling repairs.
