Drainage cell is a lightweight, high strength modular drainage cell designed primarily for sub-surface drainage

Drainage cell, drainage sheet, drain sheet 

  Drainage cell  is a lightweight, high strength modular drainage cell designed primarily for sub-surface drainage and waterproofing membrane protection or to form tanks for underground storm water infiltration or storage. Drainage cell  is manufactured from high strength polypropylene and finds application in the construction of roof gardens, plaza decks, basements, pond filtration systems, concealed drains, pre-cast and in situ drains and sports fields.Drainage cell eliminate the need for an additional protection layer when installed with a waterproofing membrane. Drainage cell when installed between roof decks and pavers or ballast, reduce sound transmission and increase heat insulation.

Unlike Sheet drain or other drainage cells, Sheet drain  are able to withstand loads imposed by wheel burrows and mechanical equipment such as Bobcats.

Available as 10 mm --- 40 mm high modules, Sheet drain modules interlock in the same plane or at right angles to one another or may be butted together.

APPLICATIONS

Drainage cell are used for sub-soil drainage and waterproofing membrane protection or to form tanks for underground water infiltration or storage systems in:                    

Benefits

Modular Drainage cell offer numerous benefits including:

§ Lightweight modules that allow easy handling and installation

§Approximately 2% of gravel aggregate weight for the same discharge capacity

§More predictable drainage capacity than gravel

§Narrow profile enables a greater soil depth to be utilised in planter beds,  compared togravel, allowing the use of a wider variety of landscape plants

§ Relief of hydrostatic pressure on retaining walls

Features

Drainage cell soffer several unique features including:

§ High compressive strength in excess of 100t/m²

§ High surface void area and internal void volume resulting in efficient water capture and discharge rates

§Modules that may be interlocked in one plane or at right angles to one another

§ Resistance to biological attack and to a wide range of soil-borne chemicals

Large pre-assembled panels that allow rapid installation and minimise on-site disruption
