Whether you use a low profile drainage channel or a 140mm deep channel drain, installation is a simple process and should take no time whatsoever.

Using either the "LibertyPLAS" shallow channel drain or the "IBRADRAIN" system, both A15 drainage channels can be used to tackle surface water build up on driveways, footpaths, patios - anywhere flooding can occur and needs to be drained! Choosing the type to suit your needs depends on a number of factors. Here we explain what the different terminology means and what choices there are to make.

What does A15 Loading Class mean?

This is a term regularly used to describe drainage channels for domestic use, such as on driveways, decking, patios and footpaths. They can take light transport, cycles and patios but are not recommended for heavy vehicle use. This makes them fine for at home but not really appopriate for areas where HGVs, trucks and lorries will pass over. For that you will need B125 drainage channels.
How to Install Drainage Channels to Combat Surface Water Build Up

Choosing between shallow drainage channels and deep channels

Within the same loading class, both types of channel drain will tolerate the same weight and type of vehicle passing over it. So in terms of choice, the difference is down to what type of excavations you can and are prepared to make. Once a choice has been made, you will need to continue using that same system if you wish to connect or extend, as the two profiles are not interchangable - i.e. you cannot use 10m of IBRADRAIN and connect to 5m of LibertyPLAS, without manual cuts and adjustment.

IBRADRAIN drainage channel carries a larger volume of water per metre but takes more excavation whereas LibertyPLAS is a shallow channel drain that carries less and requires less digging.

All drainage channels should be fixed in place using concrete, to prevent movement and the possibility of cracking. Essentially the concrete acts as reinforcement and the plastic holds and redirects the water, like a waste pipe.

Boltless vs bolt connected channel drain grating

This comes down to the design. Both the IBRADRAIN and LibertyPLAS A15 channel drains have boltless grates which attach to the gullies via pre-moulded fasteners that unclip. There are no bolts and therefore no risk of rusting.

Bolted drainage grates are fastened to a fastener thread connected to the gully directly, pulling the grate and drainage gully tightly together. This security makes sure the grate doesn't move at any given time but makes access to the drain beneath more difficult when trying to clean. Bolts need to be stainless steel or rust resistant by other means otherwise access may be restricted permanently by corroded bolts that won't unfasten.

You need easy access long term to maintain and clean your drains, to prevent long term flooding problems. This is why in our design of IBRADRAIN, the grates unfasten simply with an unclipping mechanism.

Angle your drainage channel towards the mains/run off

This sounds like a very obvious statement but it is an important one to stress. Without a 5 degree angle towards your run off/mains point, the drains will simply act as sumps where the water will collect and stand. Without the angle, you will have simply moved the build up from one location to another. The surround also needs to be angled towards the channels. This only needs to be slightly angled, especially where block paving , concrete or slabbing is concerned.

Connect corners and end caps to save cutting the drains manually

Both systems come with compatible end cap and corner units which slide onto the male-to-female ends in exactly the same way the drain channels connect to each other. All corner units are designed with outlets in all 4 directions, allowing you to create T junctions and X junctions as well as straightforward corners. This makes going around a building easy and straightforward.

End caps are used to stop concrete from pouring back into the drain during setting. They also can be used to prevent water moving in one direction or another, directing it towards the eventual run off point you need.

Simple installation -

We believe IBRADRAIN and LibertyPLAS are the best suited product for use at home, installing new driveways and preventing flooding. While we take great care to explain the differences between these two, it's important to note that the two systems and their respective components are not interchangable: you will need to order the corresponding corner, end cap or sump to match the drain channel you need.
