The Product

Thor Helical bars are highly deformed reinforcement rods that are generally used for stitching cracks in walls. The crack stitching process delivers an effective and durable masonry repair by introducing into the wall fully concealed tension straps, which strengthen fractured masonry and brickwork. The helical bar together with WHO-60 grout enhances the tensile, shear and flexural capacity of masonry walls. Once installed it progressively accumulates building loads, dispersing them back into the structure to strengthen cracked walls and provide resilience against further cracking

    Features and Advantages

    • Structural integrity.Helical design distributes loads uniformly over a large surface area and reinforces the masonry construction
    • Cost effective and easy to install. Installs into the mortar fully concealed, and preserves the appearance of the structure
    • Corrosion Resistant bars.Type 304 or 316 Stainless Steel offers superior corrosion resistance and it more reliable than crack injection methods
    • Patented manufacturing process results in consistent uniform helix configuration (U.S. Patent 7,269,987)
    • Identification of product source.“Thor” name printed on each tie for easy identification and inspection
    • Preservation of building design. Permanent solution that restores the original aesthetics of the building and reduces likelihood of further cracking nearby.
    • Environmentally friendly. It is a sustainable solution preferred by Architects and Engineers that prevents disruptive taking down and rebuilding.
