Soakaway and Percolation Testing
Soakaway testing in accordance with BRE DG 365 forms a common part of ground investigation.
Percolation testing provides information for the design of foul drainage systems and is undertaken in accordance with BS6297, Building Regulations Approved Document H and Environment Agency guidance.
BRE DG 365 Soakaway Testing, Cornwall
In-situ soakaway testing was undertaken in accordance with BRE DG 365, as part of a wider geotechnical investigation and contamination assessment for the residential redevelopment of land near Newquay, in Cornwall.
The testing was undertaken using machine-excavated trial pits, with a tractor-towed water bowser used to provide the large volumes of water required for testing. Where practicable, Ruddlesden geotechnical use local plant hire firms and agricultural contractors for all of our ground investigation work.
Ruddlesden geotechnical worked closely with the consulting engineers to ensure that sufficient information was provided for surface water drainage design.
Due care was taken to appease local stakeholders, siting the test locations to minimise excessive disturbance to existing agricultural land and ensuring that all test locations were reinstated with the upmost care to mitigate against any future damage to agricultural plant and/ or livestock.
