BAL Flexbone – the architect’s choice for fast track floor tiling on any substrate

When specifying floor tiling, products that save time and ensure the project is fail-safe are always valued.

Providing fast-track project completion and protection against lateral movement, new BAL Flexbone uncoupling solutions provide architects and designers with all the answers.

Uncoupling mats provide a protective layer between substrates which have the potential to contract or expand such as concrete, sand and cement, anhydrite (calcium sulphate) screeds or heated screeds.

Failure to protect against this lateral movement can cause tiles to either fracture, or de-bond from the background.

Following the launch of the award-winning BAL Rapid-Mat in 2014, the Flexbone range offers two very different solutions to the UK market with the launch of Flexbone 2Easy and Flexbone VAried.

Unique to the UK, BAL Flexbone 2Easy is a floating mat system – this means that no adhesive is required underneath the mat i.e. the mat is truly uncoupled!

Because no adhesive is required, as long as the floors are level and solid, preparation of the substrate is reduced to a quick sweep of the floor. No removal or residue, no removal of laitance and no priming of the surface is needed. This means that contaminated and stained floors, wooden floors, cracked screeds and mixed substrates can be tiled immediately.

As well as time savings from the lack of preparation, materials costs are also significantly reduced with no need for primers, plus a massive adhesive saving of 2kg/m², when compared to laying bonded cavity mat systems.

Time trials indicate the removal of subfloor preparation for installations provides a circa 50 per cent time saving!

Lengthy waiting times on new screeds are avoided as Flexbone 2Easy can be laid on new sand:cement screeds when they are ready to be walked on, or new anhydrite screeds that aren’t fully cured (up to 1.5 per cent CM residual moisture). This means no more projects on hold for weeks on end waiting for the screed to dry!

Fast-track installation is possible as any residual moisture in the substrate is distributed evenly through a system of perforations and channels in the mat, meaning the screed can fully cure under the tiling with no issues.

Because BAL Flexbone 2Easy is laid loose as a floating system, it is perfect for heritage projects where it is necessary to protect historic, sensitive substrates, or rental properties where tenants cannot alter the original décor, plus areas where the ability to change the floor fairly regularly can be a requirement – e.g. retail stores.

BAL Flexbone VAried is a bonded mat system, with the same installation process as other fixed cavity mat systems in the market. 

Unique to BAL Flexbone is the patented GripLock Technology and unique bone structure.

The patented design has been independently tested to provide the highest shear strength (providing more accommodation of higher levels of lateral movement) and the highest tensile strength (to stops tiles ‘popping-off’, or cracking under pressure). These highly flexible and deformable properties ensure all tile installations are protected from lateral movement and pressures, while a special fleece provides for vapour pressure compensation.

As well as providing long-term benefits in terms of strength and flexibility, the unique bone structure also makes for significantly faster installations as the design ensures the trowelling-out of adhesive on the surface layer is fast and easy.

Fixer trials have shown that the unique bone-shaped cavities are much easier and faster to fill with adhesive than the conventional square or round cavities.

Less adhesive is required, and trials indicate areas can be completed circa. 30 per cent faster.

BAL Flexbone VAried can be used anywhere – for a varied number of installation environments!

BAL Flexbone VAried provides a waterproof layer, meaning no tanking is needed in wet areas such as bathrooms, showers and wetrooms when BAL Flexbone VAried is installed.

The bonded mat is perfect for high load-bearing and commercial areas such as shopping malls, airports, car showrooms, office building and hospitals, as well as light or medium traffic areas.

Both mats are available in 20m rolls or easy to install 2x1m sheets and are suitable for use with all tile types, including natural stone.

As with all BAL products, BAL Flexbone uncoupling mats come with the manufacturer’s unique 25-year guarantee – unlike other cavity mats available.

When used with BAL adhesives, grouts, and sealants, this provides a fully guaranteed tiling system.
