Soil Environment Services

We assess soils on sites ranging from nature reserves to contaminated building sites

Site Investigation for Foundations
Soil Environment Services specialise in geotechnical site investigation soil surveys for residential developments and self build projects. Our surveys have been used for NHBC warranty purposes and foundation design*.  Foundation depth requirements in relation to nearby trees are determined on sites with clay soils.

 

All our geotechnical work complies with BS5930, BS1377 and Eurocode 7.

 

We can work in difficult access areas and leave virtually no disturbance.

 

Our typical geotechnical survey includes:

  • Boreholes to depth for a log of soil conditions and soil sampling.
  • In-situ testing:
    – SPT, Dynamic Probing or shear vane testing for ground strength
  • Laboratory testing for determination of:
    – Plasticity index to assess soil shrink and swell
    – Soil pH and Sulphates for concrete specification
  • Reporting
    – Borehole logs
    – Drawing of borehole locations and other site features of concern
    – Foundation depth in relation to soil shrink/swell and nearby trees
    – Ground bearing determined using industry software from N values
    – Concrete specification re aggressive ground

 

Our typical survey takes less than a day on site. Please download our information sheet here.

 

 

Other associated tests we can undertake:

  • Soakaway test to BRE365 specification or a ‘falling-head’ test in the boreholes.
  • Waste Acceptance Criteria (WAC) testing to take material off site to landfill.
  • CBR testing on site for road and car park sub-base specification.

Soil Environment Services undertake this work across the UK.

*NHBC and structural engineer requirments for an investigation may vary and hence we recommend you consult with appropriate persons before finally instructing us to proceed.
