Threshold Drains | Threshold Drainage | Drainage Channels

Threshold drainage solutions are an essential aspect of modern construction, offering efficient water management around doorways and other threshold areas. In this category, we focus on a variety of threshold drainage products, each designed to cater to different needs and environments.

Domestic Drainage Channels

Domestic Drainage Channels are a key product in this category. Available with various grating options like Heel Safe Polypropylene and Pave Slot Galvanised Steel, these channels ensure safe and effective water drainage in residential areas. They are typically one metre in length, ideal for standard applications. The Heel Safe grating is particularly beneficial in areas with foot traffic, as it prevents heel traps.

Industrial Drainage Channels

For more demanding environments, Industrial Drain U100 Channels made of Polymer Concrete with D400 Steel Grating are offered. These are designed to withstand heavy loads and high traffic, making them suitable for industrial areas or places with heavy vehicles.

Corner Pieces and Adaptors

Corner Pieces for domestic drains, available with Polypropylene or Galvanised Steel Grating, facilitate seamless drainage around corners. Additionally, the Domestic Drain Pave Slot Corner Adaptor provides versatility in connecting and adapting the drainage system layout to fit specific site requirements.

Accessories

Complementing the main drainage channels are various accessories, such as the Domestic Drain Accessory Pack, End Cap Outlet, and others. These accessories are crucial for the complete installation and functionality of the drainage system, ensuring a watertight and efficient setup.
