Underfloor Peace of Mind.
The APD StormSlab® is a versatile system for restrictive sites!
StormSlab is an innovative stormwater detention and retention system designed to place storage underneath the building slab. Replacing polystyrene slab formers, our tanks are available in a range of sizes to economically store the required volume with no in-slab connections. StormSlab is ideal for sites where there is a lack of space or minimal fall to public connections.
Complete solutions by APD
The StormSlab system is supplied with a distribution chamber with sealed lid meeting NZBC requirements and preventing ingress of surface water. StormSlab can be configured with the RainWorx rain harvesting and reuse system for retention applications.

- All StormSlabs are 1100mm wide to match standard pod configurations.
- Manufactured from water tank grade PE material suitable for below ground installation.
- Designed and made in New Zealand for local conditions.
- 300mm deep for extra storage.
- 220mm deep to match polystyrene pods.

Benefits
- External connections via a manifold offer better access for inspection, cleaning, or modification of the distribution pipework and control structures compared to fully encased systems
- Reduced Risk: external connections eliminate the risk of leaking or failing under slab connections
- The specially designed distribution chambers integrated silt trap ensures tank contamination is kept to a minimum protecting the life of the asset and minimising maintenance.
- The distribution chambers sealed cast iron lid protects against ground water ingress preventing contamination of the tanks and minimising maintenance.
- Tank volumes quoted are the “useable” volume not the gross volume, ensuring the volume used is the storage volume available to the homeowner.
- The wide tank range allows for simplified slab design providing the designer with greater flexibility
- Cheaper installation: Any certifying drainlayer / plumber can install the tanks and issue the PS3, meaning the installation timing is able to meet the building program not the installers program
- Lower installation cost: No additional onsite inspections as all tanks are tested and passed before leaving our factory providing piece of mind, ensuring the tank is fit for purpose and ready to use when it arrives onsite
- Simple and quick: for under lawn installation, it is as simple as using the recommended quantity of the well-known and proven APD ground anchors. No aggregate or concrete to hold things down
- Easy access: the external connections via a manifold offer better access for inspection, cleaning, or modification of the distribution pipework and control structures compared to fully encased systems
