Solution:
SUREGROUND™ Reversible Soil Enhancement System
The scheme required Soil Science to both install and decommission the ground using the SUREGROUND™ Reversible Soil Enhancement System on behalf of the main contractor Bam Nuttall.
During construction, topsoil was stripped and bunded before the proprietary binder was rotovated with soils using a Stehr dust free mixer. This was surfaced with SUREGROUND™ Maintenance Free Surface Armouring saving further costs.
The enhanced area was then decommissioned by the introduction of a bespoke reagent, the composition of which was specific for the site soils. This restored pH and nutrients to within their pre-start DEFRA indices.
The area was stripped of stone surfacing and this was recycled. The reagent was then mixed with previously enhanced soils before topsoil was spread and turf was applied.
