New Build HeliBar
Structural reinforcement bar for strengthening new build masonry and creating beams
HeliBars are slim, stainless steel helical bars that can be cut to any length to suit a variety of different new build and remedial applications...Learn more
In new build settings, HeliBars offer an ideal means of cost-effectively providing new masonry structures with reliable, long-term, engineered reinforcement. Bedded into the mortar of new masonry during construction, HeliBars are simple to install and work by bonding with the masonry to form reinforced beams which distribute structural loads.
HeliBars are manufactured from austenitic stainless steel, Grade 316 as standard, for high corrosion resistance, and to a unique, hi-fin helical design that provides a large surface area to cross section for great bonding characteristics.
Cold rolled, under tension, from continuous runs of stainless steel wire, HeliBars exhibit a compact profile that allows for easy transportation and on site manipulation whilst maintaining impressive and reliable tensile strength...Learn more
Typically, HeliBar with a nominal 6mm diameter will be used to provide new masonry with durable, engineered reinforcement. At this diameter, HeliBars can be bedded into the mortar of the new masonry during construction to provide a fully concealed reinforcement solution.
Multiple 6mm HeliBar can be run in parallel in individual bed joints to accommodate a variety of span and load requirements. 4.5mm, 8.0mm and 10.0mm diameter HeliBar sizes are also available to achieve particular construction requirements. New build HeliBar may also be used in combination with StarTies and DryLink connectors.
New build applications
Reinforcing masonry.Commonly, cracks can be expected to develop over time in masonry due to the influence of seismic events and ground movement, building settlement and masonry shrinkage, and as a consequence of changing structural loads. Areas above the corners of openings are particularly prone to cracking. HeliBars installed into the masonry above the corners of openings during construction will cost-effectively help to minimise the likelihood of cracking by tying the new build masonry together and distributing loads.
Reinforcing shallow masonry walls to resist cracking.Shallow masonry walls that do not support large compressive loads, like garden walls and walls constructed below windows, are particularly prone to cracking due to ground movement. HeliBars installed close to the top and bottom of shallow walls will contribute to the formation of masonry beams that distribute stresses and minimise the likelihood of cracking.
Creating load-bearing beams.HeliBars when used for remedial purposes stabilise and reinforce existing masonry by forming beams that distribute loads that are, in many circumstances, largely indeterminate. In new build situations, where loads are able to be defined and the characteristics of the masonry can be predicted and controlled, HeliBars provide similar reinforcement but also allow for the development of new masonry designs. Where appropriate, HeliBars may be used to form a load-bearing concealed lintel. HeliBar technical design data are supported by comprehensive independent laboratory tests.
