Dynamic Sampling was Preferred Method of Investigation in Devon

Dynamic sampling (windowless sample boreholes) was utilised in a scheme of works for the proposed stabilisation and reinstatement of a quay wall. This was the preferred method for the initialgeotechnical investigationat this site, as they allowed representative samples of the near surface soils to be obtained, facilitated Standard Penetration Tests (SPTs) and were able to be progressed down to depths of 6m-8m to determine the presence of engineering rock-head, all whilst keeping site disturbance and the areal extent of the site works to a minimum, allowing the adjacent car park to be in continued use without the need for closure.

On completion of the ground investigation, the boreholes were either installed with monitoring wells, to facilitate long-term groundwater and/ or ground gas monitoring, or backfilled with natural arisings prior to reinstatement.
