Channel drainage – modular, easy install and low maintenance


Efficient and effective channel drainage not only prevents potential damage from standing water but also maintains the aesthetic quality of a property and its surrounds. Manthorpe’s channel drainage systems are suitable for use with, patios and paths around the home, and work with all types of paving including block, flagstones, tarmac and concrete.

The modular nature of these channel drainage systems makes them highly adaptable to various scenarios including driveway drains, where efficient drainage can often be overlooked or relegated to an afterthought. The SmartDrain drainage channel is supplied in individual 1m lengths which can be extended by simply clipping on further lengths. Similarly, the sections can be easily cut to size to ensure a precise fit. The four-way junction unit acts as a multi-purpose junction box. The unit can be trimmed on-site to create right-angle, T-junction and crossroads junctions.  The channel and junction units are both heel and child-friendly and available in both silver and black finishes.


Path, patio and driveway drains – discreet solutions

When the spec for a driveway drain or any channel drainage is more stringent and a less conspicuous installation is required, the SlotDrain, once in place, leaves just a 20mm drain visible at the surface. Used in conjunction with the SlotDrain Junction unit as end pieces or at 3m intervals to enable rodding and cleaning, the SlotDrain can be used for patio, path and driveway drains and is not only independently load tested, gaining an A15 load rating but is also particularly suited to part M building regulation thresholds. As with the Smart Drain, the SlotDrain junction unit permits the installation of corners, and 3- and 4-way junctions.

Our channel drainage systems are entirely British manufactured, as are the majority of our products; proudly supporting British manufacturing and minimising risk in the supply chain and in your project schedules.
