Sheet drain

Sheet drain is made by high polystyrene particle, which is drainage system applied in vertical or horizontal waterproof project such as retaining wall, garden roof, garage roof.

It is composed of two part layer : the dimpled core and filter fabric.

The dimpled core creates an air space for water to enter and travel to its collection system. It consists of a polymeric core with its own inherent strength to withstand compressive strengths from vertical applications of soil and/or stone backfill or vehicular traffic in horizontal applications. The core height ranges from 0.25 inches(10cm) to relatively 0.5(25cm) inches

The purpose of the filter fabric is to provide a layer of filter between the unwanted soil particles and the dimpled core. The filter fabric has a high filtration rate allowing water to filter through the fabric and enter the drainage core quickly yet resist clogging. The fabric is glued to each dimple of the polymeric core to keep from soil intrusion. Various fabrics are available to meet special specification needs as well.

Feature: Sheet drain can stop the water and drain the water outside as the design direction. It is a good drainage system material in many landscape project, underground structure.

Application area: underground base, garage roof, artificial greensward etc.,
