Floor level drain Wiper Invisible 1100 mm is stainless steel shower gully without vertical frame, which gives it flexibility to be installed under any finish material. It is most commonly used to be in vinyl, marble, stone, exotic wood or glass floorings. Entire drain including the grating should be covered with your finish material so only channels for water to flow are visible after installation. It comes with insulating flange and sealing membrane which allow to achieve 100% waterproof seal.

Wet room drains Invisible have included grate 80 mm wide and total width with flange is 140 mm. Cover is 1094 mm long and drain 1160 mm long in total. It should be covered entirely with floor finish material, best if it's edges could be properly adapted to leave sufficient amount of space for gaps for water to flow. Fabric for cleaning purposes before sticking finish material to cover is included.

Convenient siphon trap with 26 l /min draining speed and 20 mm tall water seal is the last element always included to every drain. Made of PVC is very flexible as it can be rotated and pipe's height can be adjusted, making installation easier. It is McAlpine product so should be suitable for any wet room pipework. It can be opened even after installation is over for easy cleaning.

Tanking kit

The tanking kit is a ready-mixed, under-tile tanking system to protect water sensitive substrates from exposure to water. Suitable for wet areas such as bathrooms, showers in residential buildings, hotels, old people's homes and hospitals. Should not be used in places exposed to pressurised water, for an instance swimming pools. Ready to use, no mixing required and easy to apply with a roller. The kit includes a high performance joint reinforcing tape to protect against movement in floor joins and corners etc. The contents are all INSIDE the bucket and the contents are protected in the bucket with polystyrene infill's to stop transit damage.The instructions are printed on the rear of the tanking kit.

For anti-moisture insulation systems in wet rooms and rooms intended for human residence. The tanking liquid is a ready-to-use singlecomponent, solvent-free sealant composed of polymer dispersion, fillers and modifying additives. When applied to the surface, upon binding it creates a flexible and water-insulating layer.

Tanking kit contains:
  • 4kg Tanking Liquid
  • 1l Primer
  • 10 Metres flexible Sealing Tape
  • 2 Flexible Pipe Collars
  • 2 Corners
Features:
  • Consumption to 1,2kg/m²
  • Solvent free
  • Drying time: 2h
Tanking liquid and primer
Tanking liquid
Tanking liquid

The tanking liquid is a ready to use, single component, solvent-free sealant mass, consisting of polymer dispersion, fillers and additives. When applied to a substrate and cured, it forms a flexible waterproofing coating. The product is intended for use inside places intended for human residence, especially in humid areas (such as bathrooms, kitchens, laundries), to perform insulation against moisture under linings and coverings, such as ceramic tiles, glazed tiles, terracotta, wooden floors and panels, and synthetic carpets.

The product is intended for priming absorbent and porous surfaces, inside and outside buildings. It is especially recommended for cement - limestone plaster, gas concrete, plaster-carton boards and cement plaster. The primer has a high penetration ability, is deeply absorbed into the substrate, thus strengthening it, while allowing for „breathing”. These benefits improve the structure of the substrates, which, due to the passage of time, have lost their appropriate parameters. The priming solution improves adhesion to the surface of other materials that will be used on the primed substrate. By reducing the absorbency of the substrate, the wear of the applied coating materials, emulsion paints, glues, mineral putties reduces as well. The solution, due to the content of the biocide and fungicide, protects the primed substrate against the formation of mold and bacteria in the product.

Sealing mat

ISOL-ONE Sealing collar
The ISOL-ONE sealing mat is made from a polyethylene film coated with a special non-woven fabric on both sides, so that it bonds with the glue layer. Its installation is recommended in all areas that require sealing. The mat is resistant to the cracking of the substrate, ensures the seal up of the entire surface, reduces installation time, allowing to lay the tiles immediately after gluing the mat.

Adjustable legs

Adjustable legs
Adjustable feet are two small metal parts that can be connected to each channel end. They allow you to precisely set the unit height and level. Thanks to the red caps you can anchor the drain to the floor. They are part of unit, included in price and always added to each drain.

Linear drains fitting instructions

Please read the instructions carefully before installation.

  1. Set the level of the finished shower floor surface and mark it on the wall in the area where the channel will be fitted (allow for the slope of the shower surface).
  2. Connect the channel to the drainage system and set the height using the adjustable legs (optional additional payment) so that the upper edge of the frame is approximately 1mm below the finished surface level of the shower.
  3. Fill the space under and around the channel with screed or a similar product to the level of the flange.
  4. Cover the flange and the surrounding area with an insulating foil in a liquid form.
  5. Apply the sealing membrane in position on the freshly applied liquid foil.
  6. Apply a second coat of the liquid foil to the whole surface of the shower area and the sealing membrane.
  7. Once the liquid foil is completely dry as per the manufacturer's instructions, the shower can be tiled (eg ceramic tiles or granite). Seal the gap between the tiles and the channel frame with flexible sanitary silicone compatible with the tile and grout colour.
  • The diagram shows various parts of the channel and their dimensions can be found on the More info tab.
  • We recommend that you do not remove the protective foil from the grating until the installation is complete
  • The instructions refer to the correct installation of the channel only and do not include information regarding insulation or other elements of the shower cabin such as sealing connections between the shower walls and floor as well as water proofing.
  • The channel should be installed together with the siphon trap and then the adjustable legs should be glued in the places shown.

1 Product review for Linear drain Wiper 1100 mm Invisible

works with marble
It's not a clamp drain as I thought. The sealing membrane and your finish material has to be glued to the steel flange. It cannot go inside the drain under the grating cause it will stop water from flowing. But it works fine with thicker material like stone or marble.
