Drainwell soakwells are only 440mm high which makes them an ideal high water table soakage solution.

What Are Soakwells?

Soakwells are underground structures that collect and release unwanted water, in particular, excess stormwater. The collected stormwater seeps back into the ground, as a result, it merges with the local groundwater. Read More...

A soak well forms a void just below the surface of the ground. The soakwell is connected by stormwater pipes which are connected to either a series of downpipes or a downpipe from gutters or surface drains.

Stormwater pipes discharge stormwater into the void within the soakwell. Water then infiltrates back into the ground.

The rate of seepage back into the ground is determined by the open area inside the soakwell.

The infiltration rate of a soakwell also depends on the absorption rate of the surrounding earth. Geotechnical engineers can perform soil tests to obtain this information, if required.

Drainwell Soakwells have a very effective infiltration surface area. For this reason, the stormwater can soak away into the ground at a faster rate than other types of soak wells.  In addition, Drainwell Soakwells are wrapped in geo filter wrap which prevents sand from entering the soak wells.

Polypropylene DIY Soakwells

Drainwell Plastic Soakwells are supplied in a flat-pack kit form, hence the term DIY soakwells. Plastic Soakwells consist of panels which are simply clipped together by hand. The plastic stormwater crates are light weight.  Furthermore, soakaway crates do not require a concrete paving slab or concrete soakwell lid above them.

Our quick guide below will show you how to install polypropylene soakwells.

How to install Plastic Soakwells

  1. Dig a hole to the size required.
  2. Level the base of the pit and compact.
  3. Backfill the pit with approx 100mm of coarse sand, and compact.
  4. Line the base and walls of the pit with Geotextile, ensuring the seams have a minimum 200mm overlap. Seal the joints with adhesive PVC tape. Allow sufficient Geotextile length to cover the surface of the Drainwell modules once positioned in pit.
  5. Once assembled, place Drainwell modules into position, on top of the Geotextile, inside the pit. Furthermore, ensure modules are placed with 440mm side in the upright position.
  6. If required, secure Drainwell modules together with clips or heavy duty cable ties.
  7. Cut holes in the correct position for inlet and outlet pipes. The outlet would usually be positioned lower than inlet.
  8. Tightly cover the sides and top of modules with Geotextile. Ensure overlaps and inlet/outlet areas are sealed with adhesive PVC tape.
  9. Backfill around the sides and top of the modules with a minimum of 100mm clean coarse sand and compact according to engineers specifications.
  10. Finally, backfill a minimum 600mm of clean fill on top of the modules and compact according to engineers specifications.

Polypropylene vs Concrete Soakwells

Polypropylene Soakwells usually cost less to install than concrete soakwells. Concrete soakwells are heavy and difficult to install. When polypropylene soakwells have been installed, it is easy to access them again. As a result they are easier to maintain.

Drainwell Soakwells can be installed under concrete slabs, as well as under driveways, and under car parking areas.

There is a cut out guide which is used to insert a 90mm PVC pipe into the side or the top of the Drainwell Plastic Soakwell.
