Ground Improvement and Specification

RSA Geotechnics expertise in earthworks and ground improvement projects include the determination of optimum soil compaction parameters, specification of fill materials, site monitoring, quality control and performance, design of cut and fill slopes and the analysis of settlement.

Working in conjunction with specialist ground improvement contractors, RSA Geotechnics are able to advise on the design, carry out the site supervision and verify the ground treatment methodologies. Over the last thirty years we have been involved with a number of ground improvement projects using a range of stabilisation techniques including:

• lime and cement stabilisation
• deep dry soil mixing
• vibro-replacement
• dynamic compaction

Our involvement and expertise can form a significant element in achieving optimum earthwork and foundation solutions, the minimum off-site removal of poor soils and hence significant cost savings.

We are also often contracted to supervise and monitor the construction phase to ensure that the engineered fill will perform its structural function in the long term.
