Pipe Rehabilitation Case Studies

3M™ Scotchkote™ trenchless pipe rehabilitation products help to extend potable water pipe service life by reducing brown and red water issues, leaks and internal pipe deterioration, but without the cost and community impacts of full pipe replacement and other methods.
