Professional brickwork restoration
The fischer Group of Companies, Germany, expands its assortment for the restoration of two shell brickwork according to DIN 1053-1 with the mechanical cladding restoration tie VBS-M. The VBS-M is approved for application in the brick center as well in the mortar joints of the brickwork. It is especially suitable for restoration in which the insulation system is post applied to the brickwork.
Two shell brickwork comprises of a non-load bearing cladding and a load bearing inside shell. Between the shells there is in most cases an air layer with or without insulation. The cladding brickwork is tension and pressure connected by wire anchors to the loadbearing shell in order to protect the façade from wind loads.
Above all, old buildings that were constructed using zinc galvanized wire anchors which have been weakened or totally rusted. Therefore the stand safety of the cladding brickwork is no longer guaranteed and has lead in many cases to drastic accidents where parts or even complete walls have collapsed. These buildings need to been renovated by which the static safety and the artistic aspect have to be taken into consideration. Therefore in many cases the cladding brickwork in listed buildings has to be renovated. In other cases the building has to be energetically modernized and an insulation system has to be applied. The fixings specialist fischer therefore now offers 2 restoration systems.

The restoration cladding tie VB 8 is based on an expansion pressure free injection technique that consists of a profiled wire anchor made of stainless steel, a nylon sleeve and the injection mortar. The restoration cladding tie VBS 8 can bridge a wall shell distance of up to 150 mm. The building inspection approval of the German institute for construction technology regulated the application in concrete, solid brick, perforated bricks, sand-lime brick and perforated sand-lime brick.
New on the market is the fischer mechanical restoration cladding tie VBS-M, that offers a secure hold due to its double expansion zones. It consists of a multi zone nylon sleeve with 2 expansion zones and a water drip spiral in the middle. The special screw available in stainless steel A4 or zinc galvanized consists of a thread, shaft, fiberglass strengthened plastic coating and the screw head. The small plug collar and screw head enables a level surface assembly, i.e. flush finish.
The water drip spiral on the nylon sleeve prevents the run of condense water into the loadbearing shell and therefore avoiding frost and possible corrosion damage. The 2 expansion zones that are anchored in the loadbearing shell and in the cladding brickwork provides a secure hold.
The general building inspection approved fixing in brick and in the joints of the cladding brickwork provides a high degree of flexibility and safety. The low embedment depth of only 50 mm allows a quick and economical assembly. The restoration cladding tie VBS-M can bridge brick shell distances of up to 140 mm.
The VBS 8 is an expansion free fixing and offers higher pullout loads with worse brickwork joint quality. The new VBS-M is the professional when the cladding brickwork has to be restored and then insulated.
