HeliTie Bar - Part 1

The HeliTie™ Bar is an austenitic helical shaped stainless steel reinforcing
material.  Being rolled form round wire the fins are work-hardened to a very high level whilst the core remains relatively soft giving the bar its unique property of being flexible yet extremely strong. The tensile strength of the base
material is more than doubled during the
manufacturing process.  The deformation of the fins makes the bonding characteristics of the HeliTie™ Bar far superior to alternative standard reinforcing materials.
The 6mm HeliTie™  Bar is used for the reinforcing of
existing masonry structures. Combined with HeliGrout 25 it can be installed into existing masonry with very little disturbance.
The University of Darmstadt, the prestigious testing body for the European Union, has performed
independent tests on the HeliTie™ Bar to ascertain its tensile and shear loadings.

HeliTie Bar - Part 2

HeliGrout 25 is a non-shrink, pumpable, high performance, cement-based grout suitable for injection with the aid of a
 HeliGrout Gun
The low liquid to powder ratio also ensures a thixotropic grout which develops its
compressive strength rapidly. When mixed, HeliGrout 25 expands slightly helping to fill all the voids into which it is
injected.
 HeliGrout 25 is suitable for bonding metal components into most masonry substrates including concrete, brick, stone, blocks etc.
 HeliGrout 25 has been found to be a much better
alternative product to polyester and epoxy resin and is
particularly useful when fire risks are an issue.
