When we create a permanent surface, like a concrete driveway or patio, it creates the need to drain excess water. The Marley 130mm Channel is ideally suited to solving any ponding or flooding that may occur in these impermeable areas.
Sufficient slope in the paving and channel should always be determined prior to installation to accommodate desired water run-off. The channel should not be installed along the line of the vehicle wheel travel.
Dig your required trench. Compact GAP7, backfill and level off.
Place channel in the trench.
Engage all modules, including bends, before backfilling.
Always backfill with concrete with the grating fitted. Haunch concrete up and around channel without leaving any empty spaces in the area below the section where the grating is fitted in all trafficable situations.
