Surface Water Drainage

Interlocking channels with plastic or galvanised grids. Domestic use.

FloDrain Domestic Channel Surface Water Drainage
Surface drainage is available with both Plastic Grate (D700) and Galvanized Grate (D701)


The system is available in 1-metre black lengths and the plastic version is manufactured from 100% recycled plastic material and provides a strong and reliable solution for domestic surface water drainage.


The cross-braced design provides added rigidity and the concave shape of the system enables the quick and easy flow of surface water into the drainage system.

FloDrain is designed to withstand the Class A loading of a standard vehicle (15kN) and has been manufactured to meet the BS EN ISO9001 quality standard and conforms to BS EN 1433.

FloDrain has the benefit of a heel guard grate incorporated into the design of the product.  In addition, the grate has a slip-resistant finish that provides additional grip in all weather conditions and reduces the chances of slipping.  Additional features include an easy to use channel-to-channel locking system that allows the user to securely click multiple channels into place for easy assembly and handling.


The channel features three outlet connections underneath the base, together with additional options at each end of the channel.  These five possible outlets for connection allow added flexibility for the user when installing.

FloDrain can be applied around many domestic areas where surface water collects including driveways and pathways. Patios and conservatories. Swimming pools and sports areas. Gardens and water features. Retaining walls.

Benefits include:
Easy to assemble, handle and install with no special tools required.
Recycled material providing environmental benefits (plastic version).
Built-in heel guard and anti-slip system (plastic version).
Simple click into place positive connection.
Innovative, lightweight and durable design.
Concave design for easy water flow.
Low maintenance is required by the user.
Easy access for channel cleaning.
5 outlet option for multiple FloDrain channel connections.
Quad connector for multiple changes of directions.

Domestic Channel Drainage - Easy To Install With Concrete or Paving

Surface water drainage systems with plastic or galvanised grids.

1. Dig a trench for FloDrain, allowing for a 50mm deep compacted sand base and wide enough for a minimum of 100mm backfill of concrete on each side.
2. Fix a string line to the finishing height of the grate 2mm below the final surface level.
3. Allow a fall of approx. 5mm for every 1m length (1:200).
4. Start installation at the lowest point of the run to accommodate any cut lengths which should be installed at the point furthest from the outlet.
5. FloDrain joints and end caps to be sealed with silicone sealant.
6. Use an End Cap at the highest point of FloDrain.
7. Connect the lowest end of FloDrain to a 110mm PVC-U BS EN1401 drainage pipe using either an end outlet or the preformed channel bottom outlet to allow water to drain away. Contact FloPlast for additional coupling details for other connections e.g. clay pipes etc.
8. FloDrain can be cut to length with a hacksaw. Install with a grate fitted.
9. Protect the grate with tape before concrete is poured.
10. Finish concrete 2mm above the level of the grate.
11. Allow 72 hours to cure before vehicle use or removing grates.
12. To remove the grate, simply run a screwdriver along the edge of the grate to dislodge.
13. If installing block paving or paving slabs, haunch around the channel with concrete to a height that allows the depth of the block or slab to finish 2mm above the level of the grate.
All FloDrain Installations must be set in Concrete.
Should additional security be required when installing channel
drainage with the galvanised grate, locking bars D725
( 2per 1 meter length) are required.
