GEOTECHNICAL INVESTIGATIONS

Easily developed land is hard to find and close to non existent Solutions to site constraints such as the difficult/problem soils, slope and groundwater conditions require knowledgeable geotechnical engineers, engineering and environmental geologists.

Thorough geotechnical investigations are pillar on which a well planned development, either large or small should be founded Knowledge of subsurface conditions through experience from other project or review of geologic information ensures that proper material, foundations, retaining systems, slope stability measures are recommended. Consultation with the client and giving advice during project inception ultimately results in structures that perform well and often cost less
