Mechanical Wall Ties

Mechanical remedial wall ties use a 304 grade stainless steel rod which is threaded and has special expanders on each end, installed simply by drilling 10mm holes at the specified intervals, insert the remedial wall tie. Fixing the wall tie simply requires the use of a cordless drill to spin the nut on the end as this tightens it allows the bar to rotate and the inner expander to engage with and tighten onto the inner wall leaf. At the correct pre-designed torque the in-built resistance offered by the special nut and bar combination is overcome, allowing the nut to rotate down the bar and tighten the outer expander to similarly engage with and tighten onto the outer wall leaf.
