Polypropylene Soakwells Perth
Polypropylene (plastic) soakwells are the modern alternative to concrete. Lightweight, trafficable, and Australian-made — they can be carried by hand, delivered and installed without heavy equipment, and placed under driveways and vehicle access areas.
Our 140 litre Versitank modules interlock on all surfaces to form a rigid, trafficable structure. Each soakwell is wrapped in a woven geotextile fabric that lets water pass freely while keeping fine sand and soil out permanently.
Polypropylene soakwells are not to be confused with plastic PVC soakwells, which are typically non-trafficable and not modular.
Also available: polypropylene leach drains — a linear drainage system approved by the WA Department of Health for greywater and stormwater disposal where soakwells are not suitable.

The soakwells below are our Versitank 140 litre polypropylene soakwells. The animations show the assembly of one, two and three trafficable modules. Unique to this product all surfaces permanently interlock.
What Makes These Soakwells Different
- Strength through interlocking dividers — each module contains rows of internal dividers that lock together on all surfaces. This gives the assembled soakwell its trafficable rating, allowing it to be installed under driveways and vehicle access areas.
- Geotextile wrapped — every soakwell is wrapped in a woven, needle-punched geotextile fabric. The fabric lets water pass through while keeping fine sand and soil out of the soakwell. Unlike organic materials, it will not rot or degrade underground.
- Built to last — polypropylene does not corrode, rust or deteriorate in ground contact, and the geotextile wrap will not degrade underground. Installed correctly, these soakwells are designed to last the life of the building.
Polypropylene (Plastic) vs Concrete Soakwells
- Equivalent strength — most polypropylene soakwells are comparable to Class C trafficable concrete soakwells in strength.
- Superior drainage — for the equivalent volume, polypropylene soakwells have significantly more surface area for drainage.
- Easier to install — able to be installed by hand or with a 1t micro excavator. Concrete soakwells require heavy equipment to lift and place.
- Versatile — polypropylene soakwells have flexibility for more suitable locations due to their modular nature.
- Cheaper — no freight cost, no plant hire, cheaper material cost overall.
How Many Do You Need?
The number of soak wells you need depends on your roof area and suburb. Our calculator uses Perth council drainage formulas to give you a recommendation in under a minute.
