Wet room Tanking Systems - Aquaproof

Aquaproof wetroom waterproofing system has been designed specifically to tackle the problem of leakages from tiled wet room areas.

Aquaproof System is independently certified according to the requirements of the European Standard "EGAG 22 - Watertight covering kits for wetroom floors and/or walls." Aquaproof System holds an official Technical Approval Certificate ETA-09/0200. By specifying a fully approved system such as Aqauproof, you can ensure your tanking is fit for purpose and has been rigorously tested to the highest standards.

Aquaproof system can be applied to wooden sheeting, plasterboard, MDF, concrete/screed and most commonly used construction boards including Wedi.

Once applied the Aquaproof waterproofing system can resist normal thermal movement in the room and will not become brittle with age.

With Aquaproof a fully tanked room can be achieved preventing damage to wall and floor substrates and leakages into rooms below.

Level Access Shower Tray Formers

Shower Tray Formers are used to create the Level Access Showers found in wet rooms. These formers are perfect for creating a contemporary showering area and also have the benefit of being suitable for creating walk in showers for people with mobility problems.

We can supply you with both standard and made to measure wet room shower tray formers, for vinyl or tiled floors. For prices and to buy online please click here.

Detailed Information
Easy to install, these patented shower trays are made uniquely from a birch ply and are guaranteed for 25 years. This incredibly strong and versatile wood product is highly resinous and, once tanked, is completely waterproof. Indeed there are companies now making bath tubs from the same material.

For the installer, the ply trays have many advantages over other alternatives: the wood construction means they are lighter and easier to handle and they can be readily shaped, on site, to fit even the most awkwardly shaped or out-of-true rooms Once fitted they can be screwed freely in to position.

There are design benefits too: our level access shower trays are only 24mm thick. Alternatives such as foam building boards are thicker and must be cut into the floor or have a step up into the room, making it more difficult to create a level showering area.

Your budget will also benefit as our shower trays are competitively priced when compared with other types of level access, wet room, shower trays.

Trays are supplied ready to lay on any substrate including timber, screed and floating floors, and are supplied with standard gravity waste.

The product has been tested to BSI standards for a safe working load of more than 60 stone (380kg) and allows conformance with the new DDA regulations and current building regulations to create level access showering for wheelchair users.

The mat is approved for laying directly onto flammable materials such as plywood. It can also be laid on concrete or screed. Thermoflex mat makes application extremely quick and easy, and for awkward areas (eg around toilet or sink pedestals) the cable can easily be separated from the matting and used loose for the desired distance.

Rising Damp Barriers

KÖSTER AQUATECNIC supply products designed to tackle the problem of rising damp in masonry. The products we offer provide long lasting solutions to rising damp but are also safe and easy to apply.

A very high specification synthetic injection resin for sealing against rising damp. KÖSTER Crisin 76 works every time even when the wall has high salt content or very high moisture content. Due to its very low specific gravity and a surface tension that is much lower than that of water, it displaces the water in the capillaries. KÖSTER Crisin 76 remains flexible even after its full cure and does not deteriorate.

From application KÖSTER Crisin 76 resists all conventional aggressive masonry compounds as well as acids, alkalines and salts.

Crack Injection Products
