EconoDrain DG-4™ combines the accuracy, cost efficiency and simplicity of EconoDrain®. Add the beauty of decorative grates and EconoDrain DG-4 becomes the system of choice for Architects, Landscape Architects, Designers and Property Owners.

EconoDrain DG-4 is a pre-engineered trench drain system made from expanded polystyrene (EPS) foam forming sections and steel frames for supporting the grates. Once these components are assembled and installed, concrete is poured around the EPS foam and frames forming the monolithic concrete trench. The EPS foam is then removed leaving the desired trench width, depth and slope. Grates are then placed in the frame and secured with a center toggle locking device.
