Following BS2898:2010 standards for the design and installation of natural stone cladding and lining, Vista stone support systems adhere to building industry regulations and best practice.
Wherever possible the recommendations in BS8298-1,-2,-3,-4:2010 “Code of Practice for the Design and Installation of Natural Stone Cladding and Lining” are used as the basis for our design.
The document discusses recommendations on all aspects of natural stone support ranging from materials to fixing positions and required bearings.
In the case of cast stone units, the fixing options are increased as cast-in fixings may also be considered.
The use of welded serrated pads and punched vertical slots on both the angle and system type brackets offers up to +/- 30mm vertical adjustment.
To specify Vista Stone Support Brackets follow the code as shown. Note:- Cavity will determine whether angle or system is used. Brackets can be supplied with a plain horizontal slot if required.

Example shows stone support bracket fixed back to concrete using an expansion anchor.
The use of a VESB1 type bracket with overbent angle ensures that the base of the stone unit is both supported and restrained with additional ties only required at the head of the unit.
Example shows VESB5 support bracket fixed back to concrete using an expansion anchor. The stone unit is both supported and restrained by the dowel with additional ties only required at the head of the unit.
The soffit stone is suspended using Vista C1 restraint ties fixed back to concrete via 28/15 cast-in channel.
