Geotechnical Engineering
GESTRA works closely with each of its clients in order to gain a distinct understanding of the project. When we fully understand the uses of the prospective property or area, we can design a unique geotechnical exploration program which will ensure that the most pertinent data is obtained. GESTRA uses its local knowledge and geotechnical expertise to assist its clients in obtaining the most cost effective and useful subsurface information.
GESTRA performs its own field and laboratory tests for almost all the services offered. We have an geotechnical laboratory and geotechnical field exploration equipment. GESTRA is equipped to handle virtually all of the laboratory and field testing needs of our clients.

Subsurface information for a prospective property or structure is imperative in order to reduce the risk of incurring extras during construction pertaining to soil and groundwater issues. If unfavorable conditions do exist, GESTRA consults with the respective party by providing recommendations for remediation options. The costs associated with subsurface remediation can make or break a project, however, if known up front, the project will be a success.
