Wall Tie Installation
Remedial stainless-steel wall ties to re-connect the outer and inner leaves of failing cavity walls — restoring structural stability before movement worsens.
Cavity-wall properties rely on metal wall ties to bond the outer and inner leaves together so they act as a single structural unit. Older mild-steel ties corrode and expand over time, cracking mortar joints and, in serious cases, causing the outer leaf to bulge, lean or separate from the inner wall.
Remedial wall tie installation replaces the failed ties with modern stainless-steel equivalents that are drilled and mechanically or resin-fixed through the wall from the outside. It's a proven, non-disruptive way to restore structural integrity without dismantling the wall, and it stops progressive damage before it becomes a much larger repair.
We survey the property to establish the extent of tie failure — typically using a metal detector and borescope inspection of the cavity — and specify the correct type, length and spacing of ties to current working standards.
