BENEFITS
PERMEABLE CONCRETE BENEFITS
+ REDUCES RAINFALL RUNOFF
With a runoff coefficient of 0.3, Permcon eases pressure on stormwater systems.
+ RECHARGES GROUNDWATER
Water filters through the slab and returns to the aquifer, just like in a natural landscape.
– CONTROLS PEAK STORMWATER FLOWS
Detains water in the base layer and releases it slowly.
+ IMPROVES WATER QUALITY
Filters out up to 70% of heavy metals, hydrocarbons, organic debris and suspended solids.
+ PROTECTS SOIL HEALTH
Allows water, air and nutrients to pass through to the underlying soil, maintaining the conditions needed for life to thrive below the surface.
– REDUCES SIZE OF RETENTION STRUCTURES
Stores water within the pavement system, freeing up usable land.
– REDUCES RUNOFF TEMPERATURE
Helps protect rivers, streams and aquatic ecosystems from temperature spikes.
+ MAXIMISES SITE USAGE
In passive systems, Permcon may be considered equivalent to grass for design purposes.
