CASE STUDY
IN-SITU SOIL STABILISATION FOR THECONSTRUCTION OF A PILING MAT
SOUTHAMPTON, MAY 2019
CLIENT: GRACELANDS AND TAYLOR WIMPEY HOMES
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
Application: Ex-situ
Our ex-situ application is for large, open projects where there is an on-going requirement for stabilisation, or sub-base material in large quantities and there is space for the stockpiling of spoil material onsite.
EXECUTIVE SUMMARY
This case study highlights the successful use of SMR through in-situ application for stabilisationin Southampton. Overcoming material quality issues and the need for high CBR values, SMR UKLtd effectively created stable piling platforms, enabling smooth building progress.
PROBLEM STATEMENT
The project faced delays due to the lack of quality crushed material locally. SMR UK Ltd wastasked with creating stable individual platforms for both Auger piling and Vibro piling, requiringa CBR value of at least 30% to support a 52-ton weight.
THE SMR SOLUTION
Following a soil analysis, SMR UK Ltd utilized its innovative SMR Proprietary Binder for soilstabilisation. A 300mm layer of SMR Proprietary Binder was introduced through the stabilisingdrum and then rotavated into the existing ground before compaction. The challenge of limitedspace necessitated precise plant manoeuvring to achieve accurate compaction for successfulCBR results.
RESULTS
Within 48 hours of the curing process, the stabilized platforms achievedCBR results of 30% and above, which continued to increase over a 7-day curing period. This success enabled the safe deployment of a 54-ton Vibro piling unit, allowing the building program to proceed withoutfurther delays.
BENEFITS
Quality Platform Creation: Successfully stabilised piling platforms forAuger and Vibro piling.
CBR Value Achievement: Exceeded the required CBR value of 30%,supporting heavy loads.
Building Program Progress: Enabled the use of a 54-ton Vibro pilingunit, ensuring uninterrupted building progress.


CONCLUSION
The application of SMR effectively addressed material quality andstability challenges, leading to stable piling platforms and the smoothcontinuation of the building program.
