T-Lock
 

50 years of proven performance without a failure! That’s 50 years and still counting! No other sewer protection system can match that record. Not plastic pipe. Not coatings or mastics. Not chemical treatment.

T-Lock is an extra -tough, specially formulated polyvinyl chloride sheeting that locks mechanically into the interior wall of concrete sewer pipes, tunnels or manholes during manufacture or rehabilitation, providing a flexible corrosion barrier that will withstand decades of severe service.

It's an unbeatable, cost-effective combination: the corrosive resistance of Ameron T-Lock and the strength and durability of concrete.

Around the world, over 200 million square feet of T-Lock lined sewer pipe are in the ground. Install Ameron T-Lock and forget it!
