P-Drain consists of a polymeric sheet cuspated under heat and pressure to form a high flow, high compressive strength dimpled Drainage core. The core is available as an impermeable sheet or punched, based on application. Impermeable core works well on slabs/indoor surfaces as it protects urine from being absorbed by the concrete. Punched core allows liquids to flow through to ground surfaces below. P-Drain creates air void so urine can be washed down through turf to avoid it being held by the turf and cause odor. It also creates a channel to convey the urine and wash down water directly to Drains.
