Concrete lining creates a protective barrier between the host structure and the environment around it. WCCL evaluates exposure to wastewater, chemicals, moisture, abrasion, and changing service conditions; prepares the substrate; and coordinates lining application and inspection to the project requirements. Proper cleaning, sound-substrate preparation, bond, thickness, and holiday control are central to long-term performance.
