Channel drains are a simple way of redirecting surface water away from the driveway
This prevents water getting into garages or onto garage areas.
You will need to work out what type of channel drain to install, based on the amount of water which the area experiences. Once you have worked this out, take it into account when planning your driveway.
Make sure you are wearing appropriate safety protection throughout the entire process.
Step 1: Footing
The channel drainage footing is the same for each driveway surface.
There needs to be a depth of 100mm concrete underneath the drain, with haunchings 100mm wide on either side of the channel.
Dig a trench the depth of the channel drain +100mm for the concrete.
Step 2: ‘Levelling’
The channel drain should sit 2mm below the surface of the driveway. Use a mallet to gently press the channel drain into the cement. Ensure that the channel drain is on a slope to the drainage point.
Step 3: Piping
Use piping under the driveway to either connect the channel drain to the sewerage system of the property or to a point where the surface run off will be diverted to an area where it will not cause damage.
Step 4: Driveway
Lay the material of your drive up tight to the channel drain to minimise the visual effect of the drain.
