About Us
Bisbee Concrete Coring was founded to provide expert site preparation services to the geotechnical, environmental, drilling, and civil industries. With years of experience in site investigation, civil, and residential construction, we built a company that prioritizes the needs of our clients.
Looking to the Future
We are working to expand our services to include:
- GPR Concrete Scanning
- GPR Utility Locating
- EM Utility Locating
- GPS Site Mapping
With this expansion we are in alliance with the National Utility Locating Contractors Association (NULCA) for the pursuit of standardizing safe practices in utility locating. Our technicians are currently NULCA certified. NULCA's Locator Training Standards and Practices are recognized by the Common Ground Alliance (CGA). In addition, we are working closely with the Small Business Administration (SBA) to become a certified Women-Owned Small Business (WOSB).
Our top priority is to continue growing our involvement with safe practices and providing quality work within California industries.
We look forward to taking on new clientele and creating long-lasting professional relationships.
