What is GreenStorm?

Excavator supported by GreenStorm blocks

Figure 1: A live demonstration featured a CAT 345 excavator standing freely on 10 GreenStorm blocks, with 5 supporting each track. The excavator, weighing as much as approximately 20 half-ton pickup trucks, remained in this configuration for about 45 days. The conclusion of the demonstration saw the excavator safely brought down, leaving both GreenStorm and its surroundings undamaged

GreenStorm, an innovative stormwater management solution exclusively produced and distributed by Stormcon for the North American market, originates from Germany and boasts a successful track record of over 30 years across Europe. What sets GreenStorm apart from other solutions is its remarkable ability to withstand up to 27 tonnes of vertical loading, while being composed of up to 70% recycled polypropylene plastic. Despite its robust construction, it remains exceptionally lightweight, facilitating easy handling in the field.

With a 100% inspectable design and a 96% void ratio, GreenStorm maximizes water storage efficiency. Engineered to meet CL-625-ONT Live Load requirements, it complies with Canadian Highway Bridge Design Code standards, adheres to ISO Standard 4981, and is an approved stormwater management product through The Road Authority agency. GreenStorm can be stacked up to 5 layers high (3.30 m) and comes with accessories such as Access Shafts, which allows for surface access without the need for human entry. Typically installed beneath roads, parking lots, and green spaces, GreenStorm combines durability, sustainability, and practicality in stormwater management.
