Product Specs and Installation Guidelines

The Grate Trench™ serves a wide range of applications and can adjust to any length. It was designed for basement floor water and leaks and protects from water coming through bulkhead doors. The Grate Trench™ solves bulkhead water problems by collect-ing surface water before it enters the basement. It's cantilever valve system opens and closes automatically to deliver basement floor water to the Grate Drain system. When not in use, the valve is air tight, sealed to prevent odors, moisture, and water form seeping back on the floor.
GrateTrench can be connected to any sub-floor drainage system or sump-liner.
