CASE STUDY
IN-SITU SOIL STABILISATION FOR A CAR PARKBASE
BRISTOL, 2013
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 focuses on the SMR In-Situ application forground stabilisation. This project was for the constructionof a load-bearing vehicle parking area for a new retaildevelopment in Abbey Wood, Filton near Bristol. By usingSMR products, the project achieved significant financialsavings, reduced environmental impact, and expeditedproject completion.
PROBLEM STATEMENT
The challenge was to convert an open field into a stableand permanent vehicle parking area for the new retaildevelopment. The project required a solution that wouldavoid excessive transportation, landfilling, and materialimport while ensuring load-bearing capacity.

THE SMR SOLUTION
The chosen solution involved utilizing a Wirtgen WR240, a specialised cold recycling and soilstabilisation vehicle, to perform all work on-site. SMR proprietary stabilisation material wasmixed with the existing soil to create the sub-base layer. This layer was then leveled,compacted, and treated with bitumen Emulsion for weatherproofing and wearing capacity.
RESULTS
The in-situ methodology using SMR achieved a load-bearing performance ranging from 30%CBR to over 100% CBR. The project completed successfully with a stable parking area, allachieved in a shorter timeframe compared to traditional methods.
BENEFITS
Financial Savings: The use of SMR’s in-situ stabilization method significantly reduced costscompared to traditional methods, delivering a cost-effective solution.
Reduced Vehicle Movements: By avoiding the need for extensive transportation, the projecteliminated approximately 630 lorry movements, minimizing carbon emissions andtransportation costs. This would have saved around 3.22 tonnes of CO2.
Timely Project Completion: The in-situ approach expedited project completion, saving timecompared to traditional methods, and delivering the desired outcome promptly.
Zero Landfill: By reusing existing material and avoiding landfilling, the project successfullyeliminated landfill costs and the need to purchase and transport new materials.
CONCLUSION
The Abbey Wood, Filton project demonstrates the effectiveness of SMR’s In-Situ Stabilisation increating a permanent structure for a vehicle parking area with substantial benefits. Byreducing vehicle movements, costs, and environmental impact, the project showcases howinnovative methodologies can lead to successful and efficient construction outcomes.
