Earthworks and Ground Improvement

Earthworks TrucksThe majority of projects normally require some form of ‘cut and fill’ activity in order to create a level development platform.

A critical factor is optimising the design of earthworks and ground improvement to minimise the cost of import or export of bulk materials from site, and limiting the environmental impact of the works.

Our ground investigation expertise in earthworks includes; classification of soils, optimisation of design, determination of soil compaction parameters, specification of fill materials, site supervision, quality and performance control through in-situ testing and monitoring, instrumentation, analysis of settlement characteristics and design of cut and fill slopes

By combining our wide range of site investigation experience and knowledge, we have designed innovative schemes for residential, commercial and highway schemes.

Our designs combine ground improvement techniques such as the use of lightweight fills, wick drainage, surcharging, lime or cement stabilisation, soil mixing, vibro improvement and dynamic compaction to provide a cost effective solutions.

Southern Testing are continuing to work through the Coronavirus (COVID-19) emergency, including carrying out site work where it is safe to do so.

The Government have given express support to the Construction sector and have issued specific guidance for working on site. The Construction Leadership Council have also issued guidance.

We have revised our travelling and working practices to ensure that our staff are protected, and to meet the particular requirements of the guidance as well as our own risk assessments. The guidance and our working practices are under constant review.

Most site investigation work can be undertaken safely under the current restrictions.

We are committed to helping all our clients, old and new, during this difficult time. Should you have any site investigation requirements, or wish to discuss a particular project, please do not hesitate to contact us.
