Combo Guard is a patented, low-cost, four-layer sediment control system specifically designed for combination curb and grate inlets. It serves as a critical component of a comprehensive Best Management Practice (BMP) approach for construction site sediment control. The system features an integrated filter with a 2-inch vertical height designed to allow water to bypass during high-flow conditions, ensuring safety by preventing street flooding while still capturing sediment.
The system is engineered for easy above-ground installation, which eliminates the need to remove heavy grates, thereby reducing the risk of installer injuries. Its durable construction is resistant to vehicular and construction site traffic, allowing it to be cleaned and reused across multiple projects. Made from recyclable High-Density Polyethylene (HDPE), the Combo Guard is UV stable and designed to last the duration of a typical construction project.
