Geotechnical Laboratory

GEOTECHNICAL LABORATORY

Being a One Stop Geotechnical Soil Investigation contractor, Foundtest also provides laboratory testing services as well. All construction materials, soil samples (disturb & undisturbed) and rock samples collected on site can be further tested in our associate labs according to the client or design engineer’s requirement.
