Helical Bars

Helical Bars are typically made of stainless steel and used for high tensile strengthening, reinforcing and stabilising of masonry for a crack stitch repair. The bars can be supplied as part of a Crack Stitching Kit or supplied on their own in a range of sizes.

Crack Stitching Kits usually cost around £100 and include around 10 helical bars and a specially formulated cement grout. Helical bar suppliers include Twistfix, Permagard, Screwfix, Thor Helical, Ancon and Helifix.

Helical Bars can also be used as part of a Timber Resin Splice to strengthen or repair timber joists.

When repairing a crack in a wall or timber with a helical bar it is important to obtain professional advice from a structural engineer to ensure the work being carried out is appropriate.
