Description
The Line Drainage Channel Sump 500mm (Slot Top Galv Steel) is a compact brickslot-style sump designed to discreetly collect debris and surface water from paved areas. Featuring a centre-aligned slot-top inlet, it blends seamlessly with brickwork, flags or paving, making it ideal for domestic or commercial hardscapes.
This B125-rated sump includes a galvanised steel slot-top grate and a removable silt bucket, allowing for easy sediment removal during routine maintenance. With a narrow centre slot aligned to sit directly between paving joints, it offers subtle surface drainage while the body remains concealed below.
Measuring 500mm in length and 100mm in width, the sump integrates directly into standard 100mm wide B125 drainage channels. A 110mm base outlet allows for straightforward connection to underground pipe systems.
Built from polymer concrete, the body is durable, corrosion-resistant and suitable for driveways, paved courtyards and pedestrianised access routes. The load rating of B125 means it can handle light vehicle traffic such as domestic cars and vans.
This centre-slot design is best used where symmetrical paving lines or central drainage access is required. It fits neatly at midpoints or ends of a drainage run, capturing silt and debris while maintaining visual simplicity.
