CASE STUDY
IN-SITU SOIL STABILISATION FOR A COMPOUNDYARD
LINCOLN, 2012
CLIENT: GEOTECH
Industry: Civils
For civils industries, we offer a permanent and temporary Soil Stabilisationsolution, for projects where large areas of ground material needs treatment,whithout having to remove material from site.
Application: In-situ
With our in-situ application, stabilisation is carried out in one continuous motion,for sub soil that needs to remain onsite to be re-used and treated, when there isno room to stockpile material.
EXECUTIVE SUMMARY
This case study presents the successful In-Situ application of SMR in remediating an unstablecompound yard in Lincoln. By utilising SMR material, the project achieved rapid and cost-effective results while minimising environmental impact.
PROBLEM STATEMENT
The compound yard’s sandy clay soil had led to instability, making it unsafe for heavyequipment like forklifts. This instability resulted in accidents, equipment damage, and the yardbecoming an economic liability.
THE SMR SOLUTION
SMR UK proposed to remediate the 3500 sq mt yard using their SMR material. The processinvolved spreading SMR soil stabiliser evenly, grinding it to a depth of 200mm in a single pass,levelling the area, and compacting it with a mechanical roller. The solution achieved an 80%hardening within two hours and full hardening 24 hours after compacting. A new wearingcourse was then added to complete the process.
RESULTS
The SMR solution successfully stabilised the compound yard, providing a stable surface forheavy equipment. The project was completed in just two days, exceeding the initial estimationof three days.
BENEFITS
On-Site Retention: The use of SMR allowed for on-site stabilisation, eliminating the need totransport new materials and avoiding costly disposal fees for existing materials. This approachminimised environmental impact and reduced the project’s carbon footprint.
Rapid Delivery: The project was completed in a shorter timeframe than anticipated, causingminimal disruption to yard operations.
Cost Savings: The use of existing material on-site eliminated the need for primary aggregatesand sub-base sourcing, resulting in significant cost savings. The project was costed at £5.95per sq metre, saving over £80,000.

CONCLUSION
The SMR In-Situ Stabilisation approach successfully addressed the compound yard’s instabilityin Lincoln. By achieving rapid results, reducing costs, and minimizing environmental impact, theproject showcases the efficiency and effectiveness of innovative stabilization methodologies.
