IMPTREX™ DRAINCELL is a light weight, high strength modular drainage cell designed primarily for sub-surface drainage. It is manufactured from high strength recycled polypropylene and used in the construction of roof gardens, plaza decks, basements, concealed drains, planter boxes and sportfields.

It is designed to withstand heavy loads imposed by mechanical equipments.

Available in 20mm and 30mm high modules. IMPTREX™ DRAINCELL modules interlock in the same plane and at right angles to one another.

IMPTREX™ DRAINCELL drainage cells are used for sub-soil drainage and to form tanks for underground water filtration in:

  • Landscape decks and planter boxes.
  • Plaza decks, balconies and pool sides.
  • Sportfields and gold courses.
  • Roof gardens.
  • Road edged drains.
  • Concealed drains.
  • Retaining / basement walls.
  • Storm drains.
  • Sub-surfaced drainage systems.
  • Ground water management.
  • Water sensitive urban designs (WSUD).
  • Interlocking cellular drainage modules.
  • Compressive strength of atleast 120 tonnes/m2.
  • Can accommodate both static and dynamic loads during and after installation.
  • Good resistance to petroleum based chemicals and naturally occuring soil chemicals.
  • Manufactured from recycled plastics hence eco-friendly.
  • Light weight @ ±3kg/m2 compared to 250 kg/m2 of gravel for the same effective drainage and can reduce slab loads.
  • No need for use of heavy machinery or skilled labour as it is light and simple to handle and install.
  • Maintains actual void size for effective drainage after backfill and compaction.
  • Creates an parch water table, providing air flow for ideal moist conditions for plant growth.
  • Cells can easily to cut to required size.
