Replacing cavity wall ties

Replacing cavity wall ties

Wall tie failure is a major cause of masonry cracking and, if not addressed, can lead to catastrophic collapse of the outer masonry wythe.

DryFix wall ties are power driven directly into both wythes, via a small pilot hole of around 6mm diameter.

OR RetroTies are driven into a 4.5mm pilot hole in the far wythe, via a clearance hole in the near wythe into which they are bonded with PolyPlus resin.

OR ResiTies are resin bonded into a 10mm hole in both wythes.
