Trench Former® System

Take control of your project with ABT’s TrenchFormer®.  This poured-in-place trench former system lets you select width, depth, shape and slope rate for a fully customizable drain.

With expanded polystyrene forms, TrenchFormer® installs 10 percent quicker than cast-in-place foundry systems without the expensive framing materials.  Each form can be sloped or non-sloped with a rounded, square trapazoidal or custom shape.

Eliminates penetration of sub floor during installation. Unlike traditional rebar stakes, Trench Former uses a U-shaped rebar legs to support and level the system, preventing penetration into the sub-slab.
