Isotech Environmental Corporation Construction
Serving the Northern California region, Isotech Environmental Corporation provides environmental consulting and remediation services for both residential and commercial properties. Based in Granite Bay, the firm specializes in pollution abatement, hazardous waste removal and disposal, and site investigations for above and underground projects. As a licensed drilling company, Isotech performs all drilling and subsurface sampling in-house, using its own equipment and personnel. This approach allows the company to control project timelines and costs. To maintain impartiality, all post-abatement inspections and clearance monitoring are conducted by independent third-party consultants. Isotech operates as a small, owner-operated business with low administrative overhead, passing resulting savings on to its clients. All hazard abatement staff are Cal-OSHA and EPA certified, and certified project supervisors manage abatement projects.
