Typical applications include around patios, swimming pools, sports courts, and gardens, across driveways, along pathways and retaining walls, in fact any area where surface water collects.

Maximum flexibility

The system's design allows maximum flexibility in length of channels, cornering, and volume of water. You can connect the Reln Surface Water Drainage System to 90mm stormwater pipes. Collection pits can be fitted with Reln Leaf Guards to prevent leaves and other debris clogging pipes, stormwaters, and waterways.

Chemical Resistance Chart

Reln’s products are generally design for use with water. Our website contains chemical compatibility guides from various polymer manufacturers, provided to help customers with most questions in relation to polymers and particular chemicals. These guides in no way provide a guarantee of performance of Reln products with chemicals. For specific chemical compatibility beyond the advice of the polymer suppliers, Reln recommend that customers conduct their own compatibility testing to establish their own suitability of Reln products in contact with chemicals.
