Incredibly strong one-piece units feature an internal baffling system (which slows down the water’s velocity and ensures even water distribution across the spillway), support cones, and re-enforced spillway. The innovative “inside the liner” design and rear liner attachment simplify installation. The top can be covered with rock, gravel, soil, or mulch to disguise. Raised front radius holds back any loose gravel, soil, or mulch used to camouflage the top of the unit. Molded gussets support the spillway lip. Completely sealed except the spillway opening to eliminate any chance of a leak due to “over pumping”
