Intract recently undertook mound rectification works at the Defence Edinburgh Precinct. These works required an innovative solution to provide longer term protection of the mounds from natural erosion, weeds and vermin.
The pre-existing mounds contained remanence of asbestos debris meaning all weed removal, treatment and ground filling preparations had to occur under asbestos controlled conditions before being coated in an erosion controlling product known as Geospray.
The product is applied like a spray grass treatment, but it forms a solid ground cover which is tinted with a terracotta colour. This solution is a great result for Defence as it will ultimately reduce maintenance costs in the future, with the Geospray having a much lower maintenance regime and cost.
The Intract team was required to build up an existing bunker mound with Elcorock sand bags, weighing approximately 1.2 tonnes each. Intract’s ingenuity was applied when it came to the Elcorock bag placement, with the design and fabrication of an excavator attachment improving the efficiency and placement of the 1.2 tonne bags. This was used to increase the bunker girth at the facility within the precinct.
