Drainage channels

Prefabricated drainage channels are used to direct surface water away from structures, pavements, and landscaped areas. In modern construction, they're commonly installed along driveways, patios, and pedestrian zones to prevent pooling and surface erosion. Builders fit them to external concrete slabs and paved areas, often using a linear drainage channel with a pre-cast or polymer concrete base. Channel and grate drains are also used to protect thresholds and garage entrances from water ingress.

Historically, similar systems made of stone or brick have been used to manage run-off from courtyards and roads. While materials and specs have evolved, the function remains the same: controlling water flow to reduce damage and maintain usability. Many installations need a drainage channel grate to prevent blockages and maintain access. Some projects need channels rated for heavier loads, especially in commercial or trafficked areas. You’ll find versions with galvanised or stainless steel grates, depending on the site and usage.
