Channel Drainage

The Channel Drain Should be Fitted in complete lengths if possible. The Channels have Male and Female ends these should be used in sequence along the length of the channel drain. Mechanical joints are used to link the channels and to connect the end cap and end outlets. Waterproof mastic can be used to seal these joints. If it is necessary to cut a length of channel these mechanical joints are lost- the cut should be made at the end of the line and an end cap or outlet bonded at this point with waterproof mastic. The Location Lugs will help to retain the end cap / outlet in position.

  1. Excavate a Trench Sized to allow a 50mm deep compacted sand base and wide enough to allow 100mm of  backfill of concrete on either side
  2. Fix a String Line for alingment of the channel, setting the height so the grate will be 2-3mm below the final surface level
  3. A 5mm per Length Gradient will assist water flow (Set Gradient if possible)
  4. An End Cap Should Be used at the Start/End/ Highest Point of the Channel 
  5. The End/ Lowest Point of the Channel should be connected to 110mm Underground Drainage to allow the water to drain away or connected to one of the outlets
  6. Install Channel with the grate Fitted The Channel should not need weighing down provided the concrete is tamped during the pouring process. Checks should be made to make sure no flotation takes place. Tape should be applied along the grate to keep it clean
  7. Allow Sufficiant time for the Concrete to cure/ set before allowing vehicles over the channel
