The purpose of site investigation is to establish parameters for foundation, substructure and infrastructure design and to assess potential geotechnical, geoenvironmental, geological and hydrological risk to humans, property and the environment.

Geotechnical engineering is the branch of civil engineering concerned with the behaviour of earth materials and the application of soil and rock mechanics for the design of earthworks and foundation construction.

A geoenvironmental investigation determines the geological, hydrological, environmental and contamination hazards beneath the site and provides an assessment of potential liabilities that may be associated with the planned development.

Our laboratory is accredited by the United Kingdom Accreditation Service (UKAS) for compliance with ISO/IEC 17025, the international standard for the management and technical competence of testing and calibration laboratories.
