IN-SITU SOIL STABILISATION FOR THE CONSTRUCTION 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
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 highlights the successful use of SMR through in-situ application for stabilisation in Southampton. Overcoming material quality issues and the need for high CBR values, SMR UK Ltd 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 was tasked with creating stable individual platforms for both Auger piling and Vibro piling, requiring a 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 soil stabilisation. A 300mm layer of SMR Proprietary Binder was introduced through the stabilising drum and then rotavated into the existing ground before compaction. The challenge of limited space necessitated precise plant manoeuvring to achieve accurate compaction for successful CBR results.

RESULTS

Within 48 hours of the curing process, the stabilized platforms achieved CBR 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 without further delays.

BENEFITS

Quality Platform Creation: Successfully stabilised piling platforms for Auger 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 piling unit, ensuring uninterrupted building progress.

CONCLUSION

The application of SMR effectively addressed material quality and stability challenges, leading to stable piling platforms and the smooth continuation of the building program.
