Trench Former

ABT Inc, is currently the only trench drain manufacturer to make assemblies that address the issues of expansion joints and control joints. In addition, all trench former product families have prefabricated "Tee" and "Turns" and have a load carry bar that addresses the structural weakness typically caused by these joints.

When utilizing any pre-manufactured system it is best to align your control and contraction joints with the natural joints that occur in a modular system.
