Description

Combo Guard (CG) is a patented, low cost, four layer system designed to reduce sedimentation into combination curb & grate storm drain inlets. It is engineered to balance the critical tradeoff between allowing water to flow off the street for safety and capturing sediment. The system filters storm water above the ground for easy visual inspection and maintenance while featuring a 2-inch vertical height to allow bypass in high flow conditions. During installation, the grate does not need to be removed, reducing the risk of installer back and foot injuries.

Features

  • Fast installation with no grate removal required
  • Significantly lower costs and one installation per project
  • Long life, UV stable, and resistant to traffic
  • Made from recycled content and fully reusable
  • Lightweight and easy to transport, inspect, and maintain
