DuraDrain from Zeager comes in light weight foam panels that install quickly and easily over existing hard surfaces or directly on top of grass, which can reduce excavating costs. It provides extra fall protection, and can reduce the amount of wood fiber needed to meet impact safety standards. Nine inches of Woodcarpet over DuraDrain is rated to 12-feet, according to the company.
The foam panels slow the decay process by giving wood fiber increased drainage, allowing water to drain quickly and easily away from the surface.
