Dormansland, Lingfield

January 2022

RML were instructed to undertake a ground investigation to determine the feasibility of a deep borehole soakaway at a site in Dormansland, Lingfield.

Sonic Drilling

A Sonic core borehole was undertaken in order to investigate ground and groundwater conditions at the site. Sonic drilling is a technique that significantly reduces friction on the drill string and drill bit by using energy resonance to affect the soil structure where it contacts the drill string. This combination makes penetrating for a large range of soils much easier. Sonic drilling is most often used when the drilling is difficult and/or the integrity of the core sample is extremely important.
