Deep Bore Soakaway Testing

Variable/ Constant Head Permeability Testing

Falling or rising (‘variable’) head tests can be undertaken in boreholes where the permeability of the ground is required for design purposes. This form of testing is often used to inform preliminary surface water drainage design where access or reinstatement requirements mean that ‘full-scale’ BRE DG 365 compliant soakaway testing in trial pits is not possible.

Ruddlesden geotechnical also commonly undertakes constant head permeability testing to provide design parameters for deep bore soakaway design.

All testing is undertaken in accordance with BS EN ISO 22282-2:2012.

Case Study

Deep Bore Soakaway Testing, Devon

A combination of in-situ constant and variable (falling) and constant head testing was undertaken to provide information for the design of a number of deep-bore soakaway drains at a residential development site in Torbay.
