Helical Bars

Helical Bars for Masonry Strengthening and Repair

Helical bars are stainless steel reinforcement rods designed to strengthen unreinforced masonry walls, reducing cracking and structural failure. Their unique twisted helix shape improves grip in mortar, making them ideal for bed joint reinforcement and various masonry repairs.

Common uses include stitching cracked walls by spanning bars 500mm on either side of fractures, creating retrofit brick lintels over openings for load transfer, and hoop-iron reinforcement to stabilize weakened walls. Twistfix helical bars are a superior upgrade to earlier models, offering consistent quality and compliance with BS EN 845:1 standards. They resist tension loads of 8 kN and are stocked in multiple diameters and lengths.

For best results, pair Twistfix helical bars with WHO 60 masonry repair grout—avoiding brittle resins—to provide a fast, effective, and cost-efficient solution for strengthening existing buildings. Contact us for expert advice and support.
