Achieve a discreet, seamless drainage finish with the 4All Black Plastic Brickslot Drainage Channel (Product Code: 30MHCCH5082). This professional solution is designed to sit almost invisibly within your block paving or slab installation, providing effective water management without interrupting the clean lines of your patio or driveway.
Manufactured entirely from durable, recycled polypropylene, this channel is 100% rust-proof and certified to A15 EN1433 standards, making it ideal for pedestrian and light traffic areas.
Key Features:
Discreet 10mm Slot: Features a narrow inlet slot that virtually disappears when installed correctly with paving up to 60mm deep.
A15 EN1433 Certified: Rated for pedestrian traffic, driveways (light domestic use), and patios (max 1.5 tonnes).
Total Corrosion Resistance: The all-plastic build (polypropylene channel and slot top) ensures longevity in all weather conditions.
Easy "Clip-Fit" Installation: High-quality channels clip together for quick and easy on-site fabrication.
Debris Guard: Includes a built-in debris guard to prevent sand and cement ingress during installation, ensuring a clear flow path.

TJ’s Tip:
When installing, ensure the top edge of your paving sits 3-5mm above the slot to guarantee all surface water runs into the drain. You will need the specific 4All Brickslot Access Quad Box at one or both ends of the run to connect to your underground pipes and to allow for maintenance access, as the slot itself is too narrow for cleaning tools.
