During heavy rain storms, brick and stone patios lack the proper drainage evacuate water off the patio surface allowing the surface to dry. Standing water can compromise the subbase causing the pavers or bricks to shift, resulting in an uneven surface. Stone drainage requires extensive excavation.
AWD soil drains provide the high flow capacity required to quickly and efficiently drain water, allowing the area to dry quickly, reduce the amount of standing water on the brick patio surface, resulting in a more stable wearing surface.
sheet can placed on compacted soil with the fabric facing up. The sand setting bed / leveling course is placed directly on the fabric. Brick or stone pavers are installed on the leveling course. This design is restricted to light pedestrian traffic only and is not intended to . Contact an engineer for design load requirements.
is designed to provide the evacuation of collected water around the perimeter of the patio to designated exits.
