Volume
The design gives a void ratio of 96%. One module holds a total of 480 litres of water.
Design
Robust design delivers outstanding load performance, capable of handling heavy traffic (SLW 60).
Stackable
Stackable modules offer large load volumes, 260–380 m³ depending on trailer or vehicle. One pallet holds 11 m³.
Simplicity
Smart design minimises the number of components. Simple assembly thanks to rotatable modules and integrated clips.
Sustainability
Made from recycled PP with good UV and chemical resistance; combined with 100% renewable energy, it has a minimal carbon footprint. Designed to last for over 50 years.
Compatibility
Compatible with our other stormwater attenuation systems. Smart combinations of variants give you a cost-effective overall solution for your needs.
PiVoid XL – Your attractive choice!
Product information
Fully flushable and inspectable with access in all directions for easy maintenance and inspection.
Unique flushing and sediment channels – both open and fully enclosed – effectively capture unwanted sediment and reduce how often flushing is needed.
Smart combinations of variants give you a cost-effective overall solution for your needs.

Accessories
Locking plug
Locking plug in "Double" or "Single" are used when joining modules in height and width respectively.
Cover plate
Cover plate with pre-marked connection sizes. Can be connected downwards or upwards (180 degrees) depending on the desired inlet height.
Corner protector
Corner protector in a robust design that gives extended support for the geotextile and any liner. Clips into the module.
Side plates
For heavy loads (SLW 60) in combination with a system height exceeding 1.5 m, side plates with a thickness of 25 mm are offered. The plates are easily assembled into a complete ”wall” and then connected with ease via clips.
For extreme loads > 60 tonnes/m² and system heights exceeding 1.5 m, our Side Plates (reinforced) with thicknesses of 50 and 100 mm respectively can be connected in a similar way. This provides durability far beyond the ordinary! The side plates naturally also contribute to increased system volume.
Inspection tunnel
Our efficient AIC inspection tunnel is another effective tool that allows full inspection of the storage system, with good access for cameras and similar equipment. It is built to the same height as the system and opens up entirely new possibilities.
Riser pipes
Riser pipes in the required diameter connect easily at the top and above the flush and sediment channel. The most common sizes are 400 mm and 600 mm. Adapters are available for all common manufacturers on the market. This gives full access down to the base of the system. Note: with a 1200 mm riser pipe, access can be arranged so that you can climb down into the system.
