Case Study
Using SMR To Stabilise Allstone’s Gloucester Compound
This case study examines how Allstone could successfully created a compound on their Gloucester site using only materials already available on-site, eliminating the need for additional purchases.
The Project
SMR UK were tasked with constructing a compound using materials already available on-site. Allstone requested a concrete-style finish, which we successfully achieved—delivering the desired aesthetic at a significantly reduced cost.
The stabilised area covered 4,135 m²
The SMR Solution
Samples of the ground were taken for testing. The mix design was required to achieve more than 50% CBR strengths to withstand heavy plant machines and high volumes of traffic.
The SMR binder was then mechanically integrated into the host material to a depth of 250mm using a spreader box and rotavation, followed by immediate compaction in a single continuous pass.
A 150mm layer of recycled type 1 stone was applied over the treated soil, mixed again with SMR binder, compacted, and adjusted for optimal moisture content. The surface was then refined with a reinforced power float finish to ensure durability and uniformity. Final performance validation through in-situ Plate Bearing Tests confirmed exceptional results, with CBR strengths consistently exceeding 150%, demonstrating outstanding load-bearing capacity.
