Prior to the Road Drain Top Slab, temporary sediment control was time-consuming. The Road Drain Top Slab is the only product you need from start to finish of the pre-curb/paving operations. Since 1999, contractors have chosen Wimco products for their ease and reusability. Contractors have been using the same device for more than six years, resulting in cost benefits that amount to multiple pay units per original purchased product.

The Road Drain Top Slab allows you to recess the drain tube to its down position during work hours so construction traffic and grading can continue unimpeded.
