Marmox Minilay Linear Drain Kit with a Slim Waste

Marmox Minilay Linear Drainage Kit with a Slim Waste transforms any concrete floor into a tileable wetroom floor. The drain is 600mm in length and can be covered with 4 different types stainless steel grates (bought separately). The Slim Waste is just 6cm deep. The stainless steel drainage gulley which has been factory fitted into a height adjustable frame which itself sits within a small rigid board. This small board provides a solid surface immediately around the drain from which the slope of the shower floor can be continued with the screed. The overlapping layer of waterproof fleece fitted to the top of this board would provide a seamless waterproof junction with the screed.

The depth from the board is 60mm.

• Create a hole in the concrete floor to form the sloping area.
• Before fitting the Minilay, line the area with the waterproof fleece running 100mm up the wall past the finished level of the floor.
• Apply the fleece back to the substrate with a thin bed of flexible tile adhesive.
• Where the drain pipe intersects the waterproof fleece, seal with Marmox MSP-360.
• The Minilay should be positioned at a level where the upper board surface is lower than the level of the main floor surrounding it.
• The linear channel drain version for use with the standard gully has feet to ensure that the channel is perfectly flat.
• Solvent weld the gully to a BS40mm pipe.
  
• Before continuing, check that water adequately drains through the unit.
• Mix up a standard screed (1 part cement:4 parts sand) and pack this into the void, using a trowel to create a slope from the edge of the board to the edge of the surrounding floor.
• When fully cured, fix the waterproof fleece overlaps of the Minilay to the sloping screed area using some tile adhesive and continue to tile the area starting from the drain and moving out to the perimeter walls.
