Masonry reinforcement plays an important role in repairing and stabilising brick, block and stone structures. From cracked brickwork to separated cavity walls, different forms of damage require different reinforcement products and installation methods.
HeliMate Australia supplies a range of products designed for masonry reinforcement and structural repair applications, including helical bars, remedial wall ties, helical coils, grout, anchoring epoxy and brick stitching equipment. The company serves customers across Australia and New Zealand.
Understanding how these products are used can help builders, contractors and property professionals identify suitable options for individual projects.
Helical Bars for Crack Stitching
Helical bars are commonly associated with crack stitching, a technique used to reinforce cracked masonry. The bars are installed into prepared mortar joints across a crack and secured with grout or another specified bonding material.
The reinforcement creates a connection across the affected section of wall and can help control the spread of cracking where the surrounding masonry remains suitable for repair.
HeliMate supplies 6mm and 8mm helical bars manufactured from cold-pressed stainless steel 316L. Standard bars are available at 1,000mm lengths, while 6mm and 8mm helical coils are available in 10-metre lengths.
These products are intended for a range of masonry and reinforcement applications, including brick crack repair.
Remedial Wall Ties
Wall ties have a different function from crack-stitching bars. They connect masonry leaves or sections within cavity-wall construction and can become particularly relevant when existing ties have deteriorated or when masonry sections have become separated.
HeliMate supplies remedial brick ties and CD wall ties in multiple lengths. The company's wall-tie range uses cold-pressed stainless steel 316L and includes sizes from 155mm through to longer options exceeding 300mm.
The company's guidance states that remedial ties can be used for brick, block and stone applications, depending on the specific repair requirements.
Epoxy and Grout
Reinforcement depends on suitable bonding and fixing materials. HeliMate supplies EzyBond anchoring epoxy and EzyGrout cementitious grout alongside its steel reinforcement products.
EzyGrout is listed in 5-litre, 10-litre and 20-litre formats. EzyBond anchoring epoxy is available individually and in multipacks.
These complementary products allow contractors to source several components of a masonry reinforcement system from the same supplier.
Why Stainless Steel Matters
Masonry reinforcement can remain within a wall for many years, making material durability an important consideration. HeliMate's helical bars and remedial wall ties use stainless steel 316L, which the company specifies as a corrosion-resistant material for its reinforcement products.
The choice of reinforcement material should reflect the environment and requirements of the project. Exposure conditions, moisture, masonry type and expected service conditions can all influence material selection.
Applications Across Different Masonry Types
Masonry reinforcement is used across residential, commercial and heritage projects. Brickwork may require crack stitching, while cavity construction can require remedial wall ties where connections between masonry leaves have deteriorated.
HeliMate's helical wall-tie guidance identifies applications including separated or bulging brickwork, cracked or unstable walls and connections between new and existing masonry.
Stone and block masonry can also require reinforcement, although the repair method must account for the characteristics of the particular wall.
Heritage Masonry
Older buildings require careful consideration during repair because existing materials, finishes and architectural details may need to be retained.
HeliMate's heritage brick repair guidance identifies crack reinforcement, remedial wall ties and structural tie bars as options for different forms of damage. The company also highlights the use of epoxy anchors and grout for suitable cracks and weak areas.
The appropriate method depends on the building and the condition of its masonry. Heritage work should be planned with appropriate conservation and structural considerations.
Selecting the Right Product
The correct reinforcement product depends on the nature of the repair. A crack running through brickwork may require a different solution from a separated cavity wall. Likewise, a localised masonry repair may have different requirements from a larger stabilisation project.
Before ordering products, contractors should establish the masonry type, repair location, dimensions, expected loads and installation requirements.
HeliMate offers different helical-bar diameters, coil lengths, remedial wall-tie lengths and complementary installation products, allowing projects to be specified around different repair requirements.
Installation Planning
Product selection is only one part of a successful reinforcement project. Installation should follow the requirements of the repair design and relevant professional specifications.
For crack stitching, this generally involves identifying suitable mortar joints, preparing slots, cleaning the repair area, installing reinforcement and securing it with the specified grout or bonding material. HeliMate's published information describes brick stitching as a process involving reinforcement bars installed within mortar joints and secured with grout.
Professional assessment is particularly important when cracking is extensive, recurring or associated with movement.
Combining Reinforcement Products
Some projects require more than one type of reinforcement. For example, a building may have cracked masonry alongside deteriorated cavity-wall ties.
In such circumstances, helical bars can address suitable cracking while remedial wall ties can restore connections between masonry leaves. Epoxy and grout can support the installation requirements of the selected system.
The products should be specified according to the engineering and installation requirements rather than simply combined as a standard package.
HeliMate Australia for Masonry Repair
HeliMate's Australian product range covers several areas of masonry reinforcement, from helical crack-stitching bars to remedial wall ties and supporting installation materials. The company's website describes its products as serving structural repair and brickwork reinforcement projects throughout Australia and New Zealand.
For builders, engineers, contractors and repair professionals, having access to purpose-designed reinforcement components can make project preparation and procurement more straightforward.
Masonry repair is ultimately project-specific. The most appropriate system depends on the wall, the damage, the cause of movement and the required performance of the repair. With suitable assessment and installation, modern reinforcement products can form an important part of long-term masonry repair and stabilisation work.
