Combination Curb and Grate
Combo Guard™ (CG) is a high performance, cost effective system designed to reduce sediment and debris flow into curb & grate combination inlets during construction. Installed above ground, it significantly improves worker safety, sediment control, ease of maintenance and monitoring.
ERTEC recommends installation with partially filled gravel bags (1/3 to 1/2 full) positioned on each side of Combo Guard. In addition to anchoring Combo Guard, gravel bags help to slow and pool water which in turns helps to deposit additional sediment prior to reaching the filter. When traffic proximity does not allow for gravel bags in the gutter pan, rebar tie-wire, cable ties (18” to 24”), anchors or masonry nails can be utilized to anchor.
Combo Guards can be installed side-by-side for long grates.
