Combo Guard is a patented, low cost, four-layer system designed to reduce sedimentation into combination curb & grate inlets. It is an important part of a comprehensive best management practice approach for site sediment control. The integrated filter has a vertical height of 2 inches to allow water to bypass for high flow conditions. The system installs above ground for easy installation, visual inspection and maintenance. Fits most combo storm drains. Resists vehicular traffic. The system is easy to install and clean, has a long life, is resistant to construction site traffic, and can be reused. The units are made from durable and recyclable HDPE.
