SMR UK Construct A High-strength Cycle Track On Highly Saturated Ground Using SMR SoilBind+ and SMR DryBind Pre-treatment

Problem Statement

GKL undertook a project at Tear Drop Lake in Peterborough, where they required a permanent cycle track with high load-bearing strength to enable emergency services access around the lake.  The project involved stabilising approximately 3,500 m² of ground and the requirement to achieve a minimum CBR strength of 50%.

During early construction, it became clear that ground conditions were worse than expected, with the proposed route fully waterlogged. Despite several unsuccessful attempts to resolve the issue, the saturated soil continued to pose challenges.

A soil analysis revealed a moisture content of 45.5%, far above acceptable limits for construction, and unsuitable for traditional methods. A robust soil stabilisation solution was needed to reduce moisture, improve soil strength, and deliver a durable, emergency-grade cycle track.

Phase 1: SMR DryBind

After several failed attempts to address the waterlogged conditions, our client appointed SMR (UK) Ltd as a specialised sub-contractor to deliver an alternative construction method using our patented binder technology.

To overcome the excessive moisture content, the ground was pre-treated with SMR DryBind—a rapid-acting, lime-free drying agent designed for saturated or slurry-like soils

A single 300mm pass was completed, allowing the previously unusable material to quickly reach a workable state.

Phase 2: SMR SoilBind+

SMR DryBind played a crucial role in reducing excess moisture and improving soil workability. Once the material reached a suitable condition, SMR SoilBind+ was applied to stabilise the ground and deliver the high load bearing strength required for emergency access.

Thanks to its instant reaction under compaction, SMR SoilBind+ immediately delivers structural strength, with performance continuing to improve over a 28-day curing period—by up to 600%.

Within just 48 hours, the ground demonstrated CBR values of 40%, and by day seven, it was already exceeding the required 50% CBR, confirming the effectiveness of the SMR UK system in transforming saturated soils into a high-performance, long-lasting structural layer.

Effective Application

The limited working space on site required precise plant manoeuvring to ensure accurate material placement and effective compaction.

Using SMR UK’s in-situ mixing method, a single pass of SMR SoilBind+ was applied to a depth of 300mm and thoroughly rotavated into the existing ground. The treated area was then compacted using a 13-ton single drum roller to achieve optimal consolidation.

This effective mixing methods, saved 250 lorry movements, 5,500 liters of diesel, and 15 tonnes of carbon emissions (in transport alone). The adoption of this process also reduced the programme time from 8 to 2 weeks.
