Durability & Maintenance

Resistance to freeze / thaw

Effectively designed water management systems incorporating Permaflow offer excellent resistance to damage caused by the ‘freeze thaw’ effect. This is achieved by the efficient movement of water through the system to lower layer management. Should water be able to settle within the Permaflow material and freeze, the open, interconnected void matrix will overcome any risk of damage from expansive forces caused by freeze thaw.


To ensure the flow characteristics of Permaflow continue to perform effectively, a regular inspection and cleaning programme should be established to prevent the void matrix becoming blocked. Light pressure washing and suction cleaning may be used. Environmental factors local to the product will determine frequency of this maintenance programme.
