BAL’s solution for specifying 2cm porcelain paving B
AL – market leaders in full tiling solutions – have a trusted system for the installation of 2cm porcelain slabs direct onto concrete.
This method incorporates the use of BAL Level Out external leveller and BAL XL Floor One large format floor tile adhesive and is most suited when fixing porcelain, pavers, slabs or natural stone (suitable for external use) direct to an existing concrete base which may be rough or impact damaged. This direct fixing method is essentially the same as internal tiling and can be used for patios, terraces or driveways.
The caveat being that expansion joints
need to be incorporated into the subfloor, and falls will need to be added to ensure rainwater drains away fully. An effective DPM should also be incorporated into any direct-to-earth subfloors. If needed, BAL Level Out can be applied
onto concrete pads – as long as they are fully cured, free from efflorescence, laitance, dirt and other loose materials. It can be applied from 2mm to 30mm and is ready to receive tile adhesive after approximately 3 hours.
However, BAL XL Floor One tile adhesive can be used directly onto tampered concrete slabs or BAL Level Out if levelling is needed – with no priming needed.
XL Floor One has been designed specifically for use with large tiles and external 2cm porcelain as it can be built up to 25mm in bed depth. Fully pourable, with a thixotropic nature, BAL XL Floor One provides excellent coverage on the back of the tile or paver – without the need for back buttering on flat

surfaces, saving contractors time and money. BAL XL Floor One has a pot life of 1.5 hours, open time of 1 hour and sets overnight in 6-8 hours for fast-track project completion. This ensures that large slabs can be fixed and maneuvered into place easily, without fear the adhesive will skin over or go off in the bucket.

Rigidity results worthy of a trophy at Wembley Alto apartments
P
art of a winning team at Wembley’s new Alto development, Sapphire has once again won praise for its innovative balcony design and unrivalled ‘end to end’ support.
Sapphire worked with Wates Construction to deliver 372 balconies for this stunning project for Quintain Estates. The Wembley Alto project, had an array of challenges from the long projection of the balconies to the internal fan extraction into the balconies. Other requirements included the need for top down installation to save time, GRC effect on balconies and balcony lighting. Each challenge is what makes Wembley Alto a dynamic residential haven with its four stunning towers. Sapphire’s innovative Glide-On™ connectors enabled a Rigid connection back to the building that far outperforms the British Standards L/180 structural deflection limits. With some of the balconies having a 1,725 mm projection, by BS EN Standards, this would be allowed to deflect by 9.6 mm at
the extent. Sapphire’s Rigidity point load tests showed minimal deflections with an average of 1.25 mm recorded. Using Sapphire’s Counter Balance Lifter (CBL) the client was able to install balconies as the scaffold was struck, saving time on the construction

schedule.
Sapphire’s innovative Cassette® design and simplicity enabled the integration of the extraction fans into the balconies, hiding the often-unpleasant fans from sight.
