Site Investigations

Soil, rock, and bedrock properties on and below your site is the critical factor for your constructions. Our geotechnical services provide you with a diverse range of testing and analyses for both surface and subsurface exploration of your site to identify the subsurface profiles and potential risks to assess how earth materials will interact with your proposed structures and to provide you the accurate recommendations.

And as the mandatory organization for the landslide studies in the country, we offer our geotechnical services for mitigation of landslides through in-situ and laboratory testing, installations of instruments, monitoring and data analyses to provide our people a safer environment.

Our services extend to In-situ test and Installations as listed below:
