IN-SITU SOIL STABILISATION FOR A CAR PARKBASE
BRISTOL, 2013
CLIENT: GEOTECH

Industry: Civils
For civils industries, we offer a permanent and temporary Soil Stabilisation solution, 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 is no room to stockpile material. 

EXECUTIVE SUMMARY

This case study focuses on the SMR In-Situ application for ground stabilisation. This project was for the construction of a load-bearing vehicle parking area for a new retail development in Abbey Wood, Filton near Bristol. By using SMR products, the project achieved significant financial savings, reduced environmental impact, and expedited project completion.

PROBLEM STATEMENT

The challenge was to convert an open field into a stable and permanent vehicle parking area for the new retail development. The project required a solution that would avoid excessive transportation, landfilling, and material import while ensuring load-bearing capacity.

THE SMR SOLUTION

The chosen solution involved utilizing a Wirtgen WR240, a specialised cold recycling and soil stabilisation vehicle, to perform all work on-site. SMR proprietary stabilisation material was mixed with the existing soil to create the sub-base layer. This layer was then levelled, 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, all achieved in a shorter timeframe compared to traditional methods.

RESULTS

Financial Savings: The use of SMR's in-situ stabilization method significantly reduced costs compared to traditional methods, delivering a cost-effective solution.

Reduced Vehicle Movements: By avoiding the need for extensive transportation, the project eliminated approximately 630 lorry movements, minimizing carbon emissions and transportation costs. This would have saved around 3.22 tonnes of CO2.

Timely Project Completion: The in-situ approach expedited project completion, saving time compared to traditional methods, and delivering the desired outcome promptly.

Zero Landfill: By reusing existing material and avoiding landfilling, the project successfully eliminated landfill costs and the need to purchase and transport new materials.

Reduced program times: By minimizing the need to remove and import material, there are no delays, and program time is almost always cut in half (at least).

CONCLUSION

The Abbey Wood, Filton project demonstrates the effectiveness of SMR's In-Situ Stabilisation in creating a permanent structure for a vehicle parking area with substantial benefits. By reducing vehicle movements, costs, and environmental impact, the project showcases how innovative methodologies can lead to successful and efficient construction outcomes.
