Brett Martin channel drain should be fitted as completelengths if possible. The channels have male and femaleends and these should be used in sequence along thelength of the channel drain. Mechanical joints are usedto link the channels and to connect the end cap andend outlets. Waterproof mastic can be used to sealthese joints.
If it is necessary to cut a length of channel thesemechanical joints are lost. A cut should be made at theend of the line and an end cap or outlet can be bondedin position with waterproof mastic. The location lugs willhelp to retain the end plate in position.
Excavate a trench sufficiently sized to allow a 50mmdeep compacted sand base and wide enough for aminimum of 100mm backfill of concrete on each side ofthe channel.
Fix a string line for alignment of the channel setting theheight such that the grate will be set 2 or 3mm belowthe final surface level.
Set a gradient if the installation will allow it. Any gradientwill assist the flow of water through the channel.
An end cap should be used at the end at the highestpoint in the drain.
The lowest end of the channel drain should beconnected to a 110mm OD drainage pipe to BS EN1401 using either the end outlet or one of thepreformed channel bottom outlets. This pipe willneed connecting to the existing surface waterdrainage system.
The channel will need to be weighted down to stopfloatation when the concrete is backfilled around thechannel. If the grate is removed for this purpose thenthe following procedure should be followed. A largeflat bladed screwdriver is inserted into one of the slotsat the end of the channel. The blade is twisted whilstthe grate is pulled upwards. The latch will disengage.This process is repeated along the length of thechannel. Where locking bars are used with metalgrates then these will need unscrewing.
The channel drain should be installed with the gratefitted. Tape should be applied along the grate to keep itclean during the concrete pour.
Concrete is poured to a suitable level. Either to a level2 or 3mm above the channel or to a level that willallow block paving to achieve the same level. Allow sufficient time for the concrete to cure beforevehicles are allowed over the channel or before thegrates are removed.
