Helical Bars

Helical bars strengthen unreinforced masonry walls. Use them to make brickwork more robust and less prone to cracking or failure under stress.

What are Helical Bars?

Helical bars are stainless steel reinforcing rods. Power rollers squeeze the rod to alter its shape. The shaped rod twists through a die to form a helix. The cold working doubles the rod's tensile strength. The twisting makes the bar more ductile.

What are Helical Bars used for?

The helix shape rod is excellent for bed joint reinforcement. The helix's peaks and troughs boost the bar's grip in mortar. Helical bars are helpful for various masonry repairs.

Use the bars to Stitch Cracked Walls. Insert a series of bars across a fracture at even intervals. Each bar must run 500 mm on each side of the crack. The bars absorb local stresses and release them over a wider area.

Use rods to form Retrofit Brick Lintels. Fit the reinforcement into two separate rows. Put a pair of helical bars in each. The bars must overhang each side of an opening by 500 mm. The spiral rods work with the adjoining brickwork to form brick beams and lintels. The lintels span window and door openings. They transfer load paths to areas of sound support.

Use the helical beams as Hoop-Iron Reinforcement. Bend the bars around corners to strap brickwork together. Helical bars help stabilise and strengthen walls that have lost some load-bearing capacity.

What makes Twistfix Helical Bars the Best?

  • They are the designers' upgrade of his earlier Helifix helibar product.
  • A unique twisting method gives our range of helical bars consistent attributes.
  • Our UKCA and CE Mark bars comply with BS EN 845:1 for strengthening masonry. The reinforcement resists tension loads of at least 8 kN.
  • The BRE publishes load tables for our bar and grout lintel system.

Twistfix keeps five diameters of spiral bars in stock. The bars are available to buy in various lengths. For best results, use the bars with WHO 60 masonry repair grout. Avoid using brittle resins as a bonding agent. The system provides a quick, easy and cost-effective means of reinforcing existing buildings. Call us for expert advice on helical bars.
