Red Colliery Shale and the Miracle Crystals

Leca® LWA provides an effective solution to under floor refurbishment. brbr Problems have arisen in late 1940's and 50's housing, where a shortage of imported wood to facilitate the suspended type floors that had been in vogue pre-war. were overcome by building up the under-floor with mining waste and to cap it off with what was often a poorly specified and uncontrolled concrete.

The only effective solution is to remove the old sub-floor and to replace with a non sulfate bearing hardcore: for example Leca® LWA insulation fill and top off with modern quality controlled concrete.
