In recent years we have been involved in assisting companies in the siting, design and construction of Wind Farms and as part of feasibility studies providing them with early advice on ground conditions, together with potential development constraints.
As part of this service, we have provided site investigations, together with an assessment of ground conditions for foundation and access road design. Some of the services have been provided as part of the development of an Environmental Statement or Environmental Impact Assessment.
Typical services we provide for Energy companies include;
At Earth Environmental & Geotechnical we offer a full range of ground investigation techniques, in-situ testing and in-house laboratory testing services. We can provide ground investigation reports or design bespoke investigations depending on the specific needs of the development site. We also offer many complementary services such as environmental impact assessments, ecological surveys and archaeological support, and foundation pull-out tests for solar farms, and wind farms. We have worked with energy companies and increasingly with Energy providers developing renewable energy including wind farms, solar farms providing ground investigations for renewable energy projects in the UK.
Trial Pits are used for sub-surface site investigations and examination of the soil, rocks and groundwater. Trial pits ideally proceed construction works to determine the geology and the water table of that specific site and are typically between 1 and 4 metres deep.
Rotary drilling is used to collect soil and rock strata samples, or to form deep observation boreholes. Rotary drilling is used for very dense soils and rock to investigate and analyse the sub-surface ground conditions up to a depth of 100m.
Cable percussion boreholes can be used to investigate the soil profile to a depth of up to 50m. Different cutting head heads are used for different soil types. Chisel for rock and hard layers, a shell for granular soils and a clay cutter for softer cohesive soils.
Window Sampling is used on soft ground and cohesive strata to extract soil, clay or sand samples for geotechnical or chemical analysis. Window sampling is a great technique to recover undisturbed samples for geotechnical and environmental analysis.
