Geologic Boreholes regularly undertake geotechnical drilling contracts for engineering consultancies, developers, architects and house builders.
Geotechnical drilling consists of generally shallow drilling into varying ground types, with the aim of establishing an exact record of the geological formation beneath the site. This data is required by engineers to establish what weights and pressures the ground can support heights of water tables and the depth that the bedrock is encountered.
This form of drilling is required whenever any form of building or civil engineering works are undertaken. The information recorded can be used to design foundation types, depth of piles and positioning of structures etc.
Geologic can undertake rotary, shell & auger and core drilling to recover samples and data, as dictated by the geology and type of information required. Trial pits can be excavated using in-house equipment.
Our drilling fleet consists of tracked rotary rigs ranging from 1Tonne to 5Tonne’s. Dando Shell & Auger (cable percussion) rigs and cut down low headroom shell & auger rigs. A tracked coring rig transported on a trailer and towed by a Land Rover, for fast and cost effective mobilisation. 1.5T mini-digger for excavating trench’s and trial pits.
Our Shell & Auger teams have experience of taking various samples and are conversant with Standard Penetration Tests (SPT’s), Cone Penetration Test (CPT’s), U4, Piston tests, vain tests, core samples and disturbed soil sample’s among others.
