The Resi Flex system of wall tie replacement is available in 4.5mm and 6.0mm diameter. It offers the advantages of a non-expanding resin fix on both near and far leaf through a 10mm rotary-percussion drilled hole - eliminating spalling of the brickwork. Proof testing of the far leaf using a Target Fixings Load Test Unit can be performed randomly as installation proceeds. Because the fixing method employed does not induce additional stresses into the substrate Resi Flex can be used in many and varied materials, and by drilling with a rotary-percussion drill - a three jaw chuck - any spalling of the masonry is minimised thus eliminating the need for cavity clearance.
The design of the Resi Flex remedial tie ensures that any potential for installer error can be minimised. The multiple drip design of each fin allows the Resi Flex to be installed at an angle of up to 25° towards the inner leaf without the possibility of any water transfer across the cavity. It is recommended, however, that each Resi Flex is installed horizontally.
