An integrated geotechnical and geoenvironmental site investigation is required at the planning stage of any residential development, prior to the start of the building work. The ground investigation will provide an assessment of the potential geological, hydrological, environmental and contamination hazards associated with the site and consider the most appropriate foundation, substructure and infrastructure solutions.
RSA Geotechnics have over thirty five year’s experience providing geotechnical and geoenvironmental consultancy to the residential building industry. We provide a range of site investigation and engineering solutions for simple small domestic extensions to complex large scale housing developments.
A knowledge of the geological conditions, site history and the environmental and contamination hazards are a fundamental part of the planning of safe, economic and sustainable future use of the site. Our range of geotechnical and environmental assessments and ground investigation services used for residential development include:
- desk study and risk assessment
- design of suitable intrusive investigations
- insitu and laboratory testing
- factual and interpretative reports
- tree/clay/foundation interaction
- soakaway drainage and soil infiltration assessment
- ground gas risk assessment
The design and scope of the ground investigations may be carried out using a variety of techniques including trial pitting, window sampling, cable percussion drilling and rotary boring.
Our reports provide detailed recommendations for foundation and floor slab design, basement construction, pavement design, and advice about preventative measures related to ground gases and soakaway drainage solutions.
