Impermeable Membranes For Attenuation
A popular use of our soakaway crates is attenuation, where rainwater is collected and held in a tank made from soakaway crates and then discharged at controlled rate. Local authorities can avoid downstream flooding and waterway erosion by making use of the slow rate of discharge.
Impermeable membrane liner is a core component of an attenuation tank and is required to ensure that water is held in the soakaway crates and does not infiltrate out into the soil.
