Meet the demands of the ever-increasing storm water regulations. Permavoid is a multifunctional storm water storage and conservation system.
With a 92-95% void ratio, you can store 3 times as much stormwater as drainage stone. Its ultra-shallow profile forms a monolithic stormwater control structure that reduces the impact of urban development. By reintegrating on-site water management in urban planning, just like in nature, cities become more resilient and are able to absorb the effects of changing weather patterns, preventing economic and ecological damage while protecting human health and well-being.
Protect mature trees, minimize subgrade and maximize the performance of permeable surfaces, creating ideal environments to promote healthy tree growth.
Lower excavation costs, avoid surface bedrock, contaminated subgrades and high water tables, increase stormwater attenuation, eliminate large diameter deep pipes, reduce flood risks, and store water under permeable surfaces.
Achieve a classic look and feel without costly irrigation, maximize LID performance by reducing storm water discharge through evapotranspiration, reduce run off and use it for irrigation.
Maximize shallow storage, add aesthetically pleasing green space, mimic predevelopment stormwater behaviour, minimize liability by controlling exposed surface water elevations, and maximize bio-remediation by storing excess run-off.
Rainfall storage on the roof allows larger building footprints while meeting LID criteria. High strength and light weight Permavoid minimize dead loads allowing structures to carry larger volumes of water and maximize plant diversity.
Eliminates collector pipe excavation and materials while increasing stormwater source control. Protects expensive synthetic infill turf fields by maximizing permeability and water storage. Eliminates settlement concerns through high strength interconnected units and load distribution. Provides the ideal base for precision graded athletic fields for all levels of play.
