Rainstore³ is an innovative stormwater harvesting and storage systems, offering maximum design flexibility to overcome site challenges - high water tables, rocky sub-bases, difficult shapes and slopes. Modular design enables any dimension for medium and large scale commercial and domestic applications.

What is Rainstore Advantage? Rainstore Advantage complements our range of environment enhancing products, delivering major economy of scale for multi megalitre installations for industrial, commercial and recreational applications. Rainstore Advantage is a unique combination of Rainstore modules and internal vertical columns providing a simple construction designed to maximise excavation to storage ratio, maximise storage volume (97% void) and maximise cost effectiveness.

Cost effectiveness with its 97% void for Rainstore³ Advantage and 94% for standard Rainstore³, very low excavation to storage volume ratio and very low installation labour costs. Especially cost effective for very large applications, we have installed 1.5 megalitres in 60 man hours.

Trafficable by any road legal vehicle, both products have been laboratory and field tested to H-20 and HS- 20 bridge loading and can be installed beneath truck and car parking bays, under slabs, roadways, playing fields or parklands.

Grasspave² and Gravelpave² are ideal invisible reinforced porous paving solutions both endorsed for heavy vehicle traffic - fire trucks and maintenance vehicles.

Slopetame² is a permanent, reinforced invisible matrix to control erosion on steep vegetated slopes and river banks. Lightweight, easy to install, three dimensional, interlocking mats of strong, flexible plastic rings keep vegetation in place and allows high permeability for on site water retention.

Draincore² provides permanent, high volume, lateral, hydraulic flow medium, designed specifically for civil drainage works. Broadly applicable for domestic through major construction projects very effective for draining sporting fields as in our Airfield system.
