Travertine wetroom by Craig Bills

Craig Bills is a master tiler and has been installing wet-rooms using Lewis Deck and concrete for over 20 years, he is a passionate advocate for the Lewis Deck system in wet-rooms and bathrooms as it give an opportunity for the floor to be 1 piece of waterproofed concrete. This makes a very robust and easy to build wet-room floor and is suitable for the most fragile of tiles including stone, porcelain, marble, ceramic or in this case Travertine without the danger of the floor deflecting under the load of either the bath or the occupants, etc and the tiles cracking.

Installing a wet-room floor using the Lewis Deck is a simple case of installing a drain onto the top of the deck ahead of installing a semi-dry concrete mix. A semi-dry mix will allow the falls to be laid in the surface of the concrete down to the drain. It is then a simple task to tank or seal the edge of the floor to the wall and apply a liquid waterproofing agent to the surface of the concrete. Tiles are then laid in the usual way over the top.
