Precast Concrete - AGRU Lined Structures

AGRU Sure Grip Liners provide a tough, protective barrier to combat concrete deterioration and add generations to the life of your system.

AGRU Sure Grip Liners shield concrete from sewer gases and other aggressive chemicals. Manufactured from high density polyethylene (HDPE) and polypropylenecopolymer (PPR), liners are available for a wide range of applications.


Available from Terre Hill Concrete Products, AGRU Sure Grip Liners can be economically installed and field welded by certified workers to provide an airtight and watertight structure that adds years to the life of the system.

Over a period of time and exposure, concrete pipes and manholes within your sewer system will begin to breakdown and deteriorate.

Now you have an economical alternative to add years to the life of your system with AGRU Sure Grip Liners from Terre Hill. Manufactured from chemical-resistant plastics, this product can be installed prior to new system construction, or economically custom-retrofitted within existing systems.

This product can conform to a wide range of shapes and sizes, it can be used just about anywhere you need protection - wet wells, manholes, vaults, chemical tanks, and wastewater treatment plants.

If you know your system is being compromised by potential concrete deterioration, don't wait any longer. Act today to get all the details on how you can protect your system, now and for generations to come.

AGRU Sure Grip Liners are intended to protect concrete surfaces from the damaging effects of hydrogen sulfide gas and sulfuric acid found in sanitary sewer systems. This product is not intended to prevent or stop ground water intrusion. The responsibility of providing a leak free precast structure rests on the utility contractor installing the lined structure.
