Sub Surface prepare and undertake site specific Ground Investigations tailored to establish the soil and rock profile and parameters to enable Geotechnical and Environmental designs to be carried out. An accurate understanding of the ground conditions is necessary for all construction projects including foundations, piling, vibroflotation, retaining walls, earthworks, slope stability, road design, dewatering, sewer construction site, tunnelling, phase 2 investigations for contamination analysis, landfill gas assessment, waste classification and waste disposal, etc.

Our aim in undertaking Ground Investigations, which includes obtaining disturbed and undisturbed samples and carry out in-situ testing (SPTs, CPTs) is to obtain information and soil parameters of the ground conditions to allow economic and safe designs to be developed and to reduce, as far as possible, the occurrence and impact of unforeseen conditions. In addition, to satisfy the requirements of our Clients’ and where necessary the requirements of any regulatory bodies, Local Authority Departments etc.

Our Contacts Managers at Sub Surface will advise on the most suitable Ground Investigation techniques for your site depending on the Clients’ requirements, proposed development, site location, anticipated geology, any Local Authority Requirements and when available, the findings of a Desktop Study.
