Description

Product Information

This 50mm shallow drainage channel is a lightweight surface water drainage system that clears standing water from paved outdoor areas. It's 1m long, 125mm wide and 50mm deep, with an internal height of 29mm and a 2.75 litre capacity per metre. This plastic drainage channel comes fitted with a grey, twin-slotted, anti-slip grate that clips securely into the channel body. It's rated to carry pedestrians and light vehicles, and has been independently tested to take loads of up to 3 tonnes, so it holds up well under everyday domestic use.

Use & Application

This 50mm drainage channel clears surface water from hard-standing areas around the home.

  • Driveways and parking areas: Lay this driveway drainage channel at the edge to catch water before it reaches the garage.
  • Patios and garden paths: This patio drainage channel clears surface water from patios, garden paths and garage thresholds.
  • New-build and refurbishment: Works with block paving, paving slabs, tarmac and concrete.
  • Modular lengths: Each 1m drainage channel section slots together, so runs of any length are simple to build.
  • Corners and junctions: Forms L, T and C-shaped runs using pre-formed cutting points along the channel.
  • 110mm and 32mm outlets: Connects to underground drainage via a 110mm soil pipe adaptor or a 32mm end cap outlet.

For other underground and surface water drainage products, explore our Drain Channels range.

Installation: Install on a 100mm concrete base with a minimum strength class of C25, with concrete haunching to support the channel side walls. Seal joints with a suitable sealant and position the top of the channel 3–5mm below the finished paving level. Follow the manufacturer’s installation guide.

Benefits

A 1m shallow channel drain that clears surface water from driveways, patios and paths.

  • Shallow dig profile: As a 50mm deep drainage channel, it needs less excavation than deeper systems.
  • Handles domestic vehicles: Strong enough for cars and vans to cross daily without damaging the channel or grate.
  • Faster installation: Built-in corner and T-junction connections cut both installation time and material costs.
  • Strong flow rate: A 21,736mm² free flow area and a 4.2 litre-per-second, per-metre flow rate keep water moving.
  • Removable grate: The plastic grate clips out for easy cleaning and maintenance.
