Wykamol Waterguard Drainage Channel

Wykamol Waterguard Perimeter Drainage Channel is a PVC Drainage conduit specifically designed for the control of water ingress in below ground situations.

It is installed at the vulnerable wall / floor junction to the soil retaining walls or, around the perimeter of the floor slab to be used in most waterproofing situations, and is particularly suited for use in conjunction with Wykamol Cavity Drain Membrane Systems.

Water entering the building through the walls is controlled behind the Wykamol Membrane and diverted to the perimeter channel at the base of the wall. The water enters the perimeter channel through predrilled drainage holes and must then be diverted to a suitable drainage point, either natural or mechanical, the perimeter drainage is set dead level and not to falls.


  • Quick and easy to install

  • Pre-drilled drainage holes.

  • Can detail around corners using the Waterguard Ancillary Products.

  • Tough and durable.

  • Part of a complete Type C cavity drain membrane system for waterproofing below-ground structures in line with BS8102:2009


Application Method:

Form a trough 130mm deep x 130mm wide in the floor at the wall/floor junction.

Apply the Wykamol Cavity Drain Membrane to the wall and finish 100mm minimum below existing floor level.

Lay a shallow bed of 20mm stone into the trough. Place the Wykamol Waterguard Drainage Channel onto the stone with the upstand to the top and flat against the waterproofing / cavity drain membrane to the wall.

Lengths of Waterguard Drainage Channel are butt jointed on straight runs using the Waterguard Jointing Sections.

The Waterguard Swept Corner Piece is used to join lengths of Waterguard Channel conduit at corners.

The Waterguard T-Piece can be used for 'teeing off' of the channel to dissect the floor or to discharge to a centrally located sump. Wykamol Floor Drain Channel should be used in conjunction when channelling across the floor.

Fit the Waterguard 50mm Channel Outlet into the Waterguard Channel at the appropriate location. The Waterguard 50mm Channel Outlet is used to take water from the Waterguard Channel or Floor Drain Systems into a sump chamber or through a wall on a sloping site to a gully.

Use Waterguard End Caps to 'cap-off' any ends of the Waterguard Channel.

Infill the remaining gap between the Waterguard Channel and the side of the trough with 20mm stone and finish flush with the flat surface of the Waterguard Channel.

When installing a membrane over the floor, make good the remaining area with 20mm stone. Lay the membrane over the floor area and seal to the wall membrane using Wykamol Corner Strip / Overtape.

When the Cavity Drain Membrane is not going to be installed over the floor, make good the remaining area with approximately 50mm screed.


It is recommended that the Waterguard Channel be jet washed via the Flexible Jetting Eye or Extended Jetting Eye, which should be incorporated in the channel system, at least once every six months.

This should be carried out by the installing contractor (under a maintenance contract) or by the property owner. During this cleaning process the pumps (if installed) should also be run with water out of the sump chamber to ensure they are fully operational and that the sump chamber be cleaned of any sludge / silt that may have accumulated.

In addition to this, the high water level battery alarm box and alarm sensor should also checked for working order.
