Vinylester resin anchor cavity wall tie
Supplier reference for vinylester resin anchor remedial cavity wall ties for masonry facade remediation on Class 2 strata buildings. High-load capacity and reliable cure in damp substrates — specified for zones where helical tie friction is insufficient. Compares Helifix, Thor Helical, Simpson Strong-Tie, and Parchem by resin system, load data, and distribution.
Vinylester resin anchor cavity wall ties
Vinylester resin anchor systems use a Grade 316 stainless tie rod installed into pre-drilled holes with vinylester resin injection for high-load cavity wall tie replacement. Vinylester achieves reliable cure in damp masonry substrates where epoxy is inhibited, and provides higher characteristic bond strengths than grout-in helical systems. They are specified for high-load zones and substrates where helical friction engagement is unreliable. Structural engineer specification is required.

Do not confuse vinylester resin anchor ties with:
- Epoxy resin anchor ties — two-part epoxy anchor systems with higher ultimate strength and zero shrinkage — preferred in dry substrates and high-strength applications — listed on the epoxy resin anchor page
- Proprietary kit systems — complete pre-packaged remedial tie kits (tie + resin + installation tool in one pack) — listed on the proprietary kit system page
- Helical grout-in ties — cementitious grouted helical ties for standard cavity masonry — lower load capacity than resin anchors but simpler installation — listed on the cavity ties — helical page
- Mechanical expansion ties — torque-set expansion anchor ties, no grout or resin — different installation method and failure mode — listed on the cavity ties — mechanical expansion page
- Polyester resin anchor ties — vinylester is often confused with polyester; vinylester has superior chemical and moisture resistance — do not substitute polyester for vinylester in damp or marine conditions
Disclaimer
This page provides general technical information only. Resin anchor tie type, diameter, embedment, and spacing must be confirmed by a structural engineer against project-specific masonry conditions and AS 3700. Resin anchor installation requires hole cleaning per manufacturer TDS — deviations from the installation procedure will reduce bond strength.
