Infiltration
Infiltration is the preferred method of managing stormwater in permeable soils when a downstream discharge network is not present or permitted. A soakaway will allow water to soak from the system into a gravel sub-base which will temporarily hold water before allowing it to seep into the ground.
For this application our Rainsmart soakaway crates are wrapped in needle punched non-woven geotextile before being buried in porous permeable soil. A pre-filter such as a silt trap or catchpit is also recommended for upstream debris removal.
Modern soakaway crates are a far better option than traditional gravel and pipe-based systems. Our Rainsmart crates have a 95% void ratio compared to 30% in traditional gravel and pipe-based systems. This means that you’ll need a smaller footprint for the same storage volume which will significantly save on installation costs while causing minimal site disruption.
