Soil Stabilisation Contractor Working | Ercall Wood College, Telford
Soil Stabilisation at Telford
An expansion was taking place at Ercall Wood College in Telford, with prefabricated buildings being errected on site. The haul road on site, however, had become too wet and muddy for the buildings to be transported on.
Moorhead Excavations were on site carrying out Civil Engineering works for Shepherd Construction, and, as our team had successfully worked with Moorhead Excavations on several occasions in the past, they contacted us to see how we could assist.
What Was Done
After an initial sampling and design exercise had taken place, it was decided that the best course of action would be to Stabilise the haul road and turning circle to strengthen it so that the buildings could be transported.
The base of the haul road (some 1,800 cu.m.) was treated with lime to achieve a CBR of 5% with the surface (some 3,700 sq.m.) being treated with lime and cement to provide a Stabilised Capping Replacement with a CBR of 15%.
The material was treated using a traditional Soil Stabilisation approach of applying the binder to the surface using a Tractor Towed Spreader and then mixing in using a Wirtgen WR2500S Rotivator. The material was then compacted, trimmed to tolerance and stone applied to the surface immediately.
Onsite compliance testing was carried out by a UKAS accredited laboratory throughout the works to establish that the required specification had been met.
Overall, the project was completed successfully and, despite there being quite a tight deadline, on time.
