Product Description

The ProTank module system is very versitile and can be utilised for leech drains (from a septic tank), soakwells (for stormwater management) or as an underground tank.

Features and Benefits

  • Strong structural design - can be installed under driveways, carparks and other trafficable areas therefore increasing the use of valuable land.
  • Infiltration - large permeable area including sides and ends.
  • Detention - Alleviates onsite/downstream flooding.
  • Retention - Can be used as a retention tank so that it is easy to collect, store and reuse precious rainwater.
  • Larger volumes with fewer modules - projects require fewer modules resulting in less assembly time.
  • Chemically inert - the units will not be affected by harmful chemicals, therefore increasing the product life.
  • 90mm and 150mm Cut Out Guides for DWV - Allows for simple pipe connection therefore less time is taken for installation.
  • UV Stablised - for increased product life.
  • 100% Recycled Polypropolene - Environmentally freindly.
  • Modular - The units interlock vertically and position horizontally to create any size and shape required.
  • Lightweight - easy to handle. No crane required.
  • Flat Pack Form - Easy to transport and save on bulky transport expenses.
