Helical bars in a kit for retrofit brick reinforcement, lintel strengthening, masonry stitching and foundation repair.
This retrofit bed joint reinforcement system utilises 6mm helical bars in the form of high tensile (circa 8kN) stainless steel rods that increase the tensile and flexural strength of masonry. Cold rolled helical bars have a nominal tensile strength that is twice that of rebar, four times that of epoxy glass-fibre rods and seven times that of wound helix plate (Ref: BRE GBG62)
Available in packs of 5 bars, including the complete fixing kit, these 7metre long repair bars are packed in a loop for ease of transportation. Some memory-coil may be retained when the Thorhelical masonry reinforcement is un-coiled.
Download the BRE Report and Load / Span Tables to establish the load bearing capacity of a brick beam/ lintel formed with retrofit bed joint reinforcement using concealled helical bars. These BRE tables relate to geniune second generation patented 6mm helical bars used with WHO-60 grout. Do not use BRE tables if using other types of helibars or grout.
The Helical Bar Kit comprises:
- 1 x Grout-Master applicator with Hi-Flo nozzle
- 1 x Helix mixer paddle & finger trowel / brick jointer
- 2 x 10kg tubs of WHO 60 masonry repair grout (yield=3l)
- 5 x 7m long 6mm helical reinforcement bars in 304 grade stainless steel
