Precision engineered solutions
Our construction ties and fixings are precision engineered from stainless steel and to a unique helical Hi-Fin design that combines great strength with flexibility, durability and holding power. All ties are corrosion resistant and flexible to accommodate normal building movements. All remedial wall ties are easy to install and test within the building under repair, leaving nothing to chance.
Material. Helifix remedial ties are manufactured from austenitic stainless steel, Grades 316 as standard. Indicative material data for our 6.0mm, 8.0mm and 10.0mm diameter stainless steel HeliBar are listed below...View table »
Precision engineering. Helifix ties and fixings are precision engineered to carefully monitored, exacting standards in our own UK-based factory and to our own unique helical Hi-Fin design. The Helifix design combines the required strength with flexibility and durability and provides great holding power in all commonly used building materials.
Strength and flexibility. The Helifix Hi-Fin design strikes a precision engineered balance between strength and flexibility.
All ties and fixings are rolled under tension from single stainless steel rods to give a unique helical Hi-Fin profile that provides stiffness compression and impressive and reliable tensile strength. Exceptionally strong, the Helifix design nevertheless ensures that the diameter of the core of each tie is kept to a minimum to ensure the flexibility necessary to accommodate normal structural movement including differential in-plane movement between connected elements.
Quality assurance. Helifix manufactures its ties under the ISO9001:2000 quality assurance scheme. Products are manufactured under tensile loads to ensure that any material flaws that may be present in the base material can be exposed and eliminated at the point of manufacture, and so that the quality and reliability of each final product can be guaranteed. All ties have been fully tested and approved by appropriate independent authorities and building materials manufacturers...Learn more »

Security of fixing. The Helifix Hi-Fin design ensures exceptional security of fixing whether used to achieve a dry or wet fix connection and provides multiple drip points to prevent cross-cavity water transfer when used in cross-cavity tying situations. The Helifix design incorporates two hardened stainless steel fins wrapped around a slim central core. The Hi-Fin design maximises the area of the fins relative to the core and the opportunity for each tie to form a strong and reliable connection with timber and masonry substrates.
In the dry fix setting (as applies with the BowTie, DryFix, RetroTie, StarTie and PatchPin systems) the helical fins allow each tie to cut a self-tapping path into even very hard materials, including reinforced concrete, and to form an exceptionally strong and reliable mechanical connection.
In the wet fixed setting (as applies with the installation of BowTies, CemTies, HeliBars, ResiTies, RetroTies, StarTies and PatchPins) the pronounced helical fins provide large clearance spaces around the central core material so that these can become fully surrounded with grout or resin without workmanship difficulties and so that an exceptional chemical anchoring can form.
