Schlüter®-DITRA 25

Unrivalled in its position as a worldwide leading product for over 25 years, Schlüter®-DITRA 25 is the unsurpassed uncoupling membrane for tile and natural stone installations and continues to be the only product of its kind to work through its patented design and geometric movement capability.

What makes it different?
Schlüter®-DITRA 25 is a polyethylene membrane with a grid structure of square cavities, each cut back in a dovetail configuration and an anchoring fleece laminated to its underside. The tile adhesive mechanically locks into cut-back indentations on the topside of the matting, eliminating the need for further anchoring mesh. This mechanical lock of the adhesive in the square cavities means that the adhesive does not adhere to the mat so no direct bond is formed, allowing for independent movement.

How it works?
The geometry of Schlüter®-DITRA 25 allows for the absorption of lateral movement in each direction. Through its unique 2 layer design Schlüter®-DITRA 25 truly separates the substrate and tile covering by creating essential free space between the layers in which the matting can move safely reacting to the movement of the substrate and surface independently of each other.

By nature single part and 3 part mats cannot function in the same way due to the fact they rely on a direct bond with the screed and surface covering. By definition these products fail to separate and rely in some instances in debonding of layers to cope with movement, leading to long term issues with loose tiles and weakened grout joints and ultimately a cracked surface covering.

Where can it be used?
What makes Schlüter®-DITRA 25 such a success is its ability to be used in a variety of applications, even on problematic substrates. Regardless of its size or purpose, whether indoor or outdoor, Schlüter®-DITRA 25 can be found functioning all over the world from domestic homes, leisure facilities, shopping centres and airports.

Schlüter®-DITRA 25 has chosen by tilers, contractors and specified by architects for over 25 years due to its unparalleled success in installations, along with the support and guarantee that comes from working with the market leader in essential solutions for tile and stone, Schlüter-Systems.

Schlüter®-DITRA 25 – the reference point for the industry
A reference point is something you can always look back to, measure quality by and ensure you’re on the right track. Schlüter®-DITRA 25 is the reference point for industry professionals thanks to its five main functions:

• Uncoupling – neutralises tensions between surfaces
• Crack Bridging – prevents movement and debonding
• Waterproofing – CE marked waterproofing system
• Vapour Management – interconnected air channels to help moisture evaporate
• Load Distribution – provides high resistance
