The Helix project in Falkirk has transformed a tired and lifeless environment. Rising high above this futuristic community landscape are The Kelpies, two fabulous 30-metres high, stainless steel sculptures of equine heads that reflect the lineage of the heavy horse of Scotland’s successful era of heavy industry.
Leca® LWA has played a key role below the surface of this project enabling construction access and land raising directly over a Scottish Water 36” fresh water trunk main and a 500mm pumped rising main.
Its specification has avoided enormous additional costs that would have arisen from the rerouting of Scottish Water’s assets. By replacing up to 1250mm of additional fill with Leca® LWA reduced the increased load substantially and was able to demonstrate that land raising could occur without undue risk. With a bulk density of just 0.3 tonnes per cubic metre, Leca® LWA has excellent insulation properties, is free draining, fire resistant, frost resistant and chemically inert with no hazardous properties. Used as a lightweight aggregate fill, Leca® LWA reduces the weight on weak substrates and against retaining structures by up to 75%.
