Grates on Hard Surfaces
GR8 Guard™ or Hard Surface Guard™ are patented, high performance, low total cost systems designed to reduce sediment and debris flow into paved area inlets during construction or semi-permanently in parking lots or industrial sites. Installed above ground, they significantly improve sediment control, ease of maintenance, monitoring and worker safety. The integrated filter is designed for concentrated flows with a high-flow bypass. The outer berm on GR8 Guard causes water to rise more 1.5 inches before reaching the filter, allowing larger particles to settle. Hard Surface Guard is 4″ or 6″ high.
