Precast concrete can offer durable and resilient systems to intercept and collect stormwater runoff. Where a durable maintenance-free permeable surface cannot be employed, engineered collection systems such as gullies and slot drains, usually feeding stormwater to an underground attenuation/ storage tank, a wetland or a detention basin, can be used.
Road gullies
Receives stormwater runoff from paved areas. Offers gravity separation of siltHigh capacity road gullies
Increase capacity road gullies to receive runoff from surfaces prone to flooding
Slot drains
Receives surface runoff and has integrated gasket joints and excellent flow characteristics
