Crack Stitching – Remedial Wall Ties – Grout Free Wall Anchors – Masonry Reinforcement Bar

Thor Helical – AISI316 Grade Austenitic Stainless Steel Helical Bar


Thor WHO60 Cementitious Grout

A shrink compensated, two-part, thixotropic cementitious grout, suitable for injection with a hand applicator, for use with Thor Remedial Reinforcement and Thor Remedial Wall Ties. Supplied in a sealed tamperproof mixing bucket, the components are mixed on-site with a drill powered mixing paddle, to a smooth creamy consistency. Manufactured in Australia for Australian conditions, (under arrangement), the high strength bonding agent is an integral proprietary component in the Thor Remedial Masonry Reinforcement System.

The combination of Thor Helical reinforcement wire with the Thor WHO60 Grout provides a stabilisation system sympathetic to active structures such as masonry.
The micro-cracking properties of the Thor WHO60 grout allows a degree of flexibility compensating for natural expansion and contraction. Higher strength grouts and polyester/epoxy adhesives may restrict natural masonry movement and induce further cracking within adjacent areas.

The fully cured polymer-modified mortar has enhanced tensile strength, flexural strength, water resistance, and chemical resistance. Additionally the polymer in the mortar helps restrain micro-crack propagation, which improves the overall toughness of the mortar.
