Wall Ties & Restraints

Wall ties and restraints are essential structural components in cavity wall construction, connecting the inner and outer masonry leaves and securing walls to the building frame. Selecting the right tie for your cavity width and wall type is critical for compliance with building regulations and the long-term stability of the structure.

Our Wall Ties & Restraints Range

McMahons stocks a practical selection of stainless steel wall ties, restraint straps, and fixings from trusted manufacturers to suit the most common cavity wall and timber frame construction scenarios.

• Stainless steel cavity wall ties - grade 304 austenitic stainless steel wire ties available in 225mm, 300mm, and 350mm lengths, with options with or without insulation retaining star clips. With-star versions suit insulated cavities up to 100mm; without-star options extend to 150mm cavity widths. Supplied in bags of 30 or 50.
• Powertie timber frame ties - high-tensile stainless steel ties for masonry outer leaf to timber frame construction, designed for 50-74mm cavities. Fixed through sheathing into structural studs and bedded in mortar. Supplied in packs of 250.
• Straight restraint straps - 900mm galvanised restraint straps in standard and heavy-duty (M305) options for tying walls to floor joists and roof structures, resisting outward movement and lateral loading.
• Herringbone joist struts - 400mm galvanised struts for bracing between floor joists, preventing twisting and improving load distribution across the floor structure.
• Tying wire - 1.6mm 16 gauge galvanised tying wire (2.5kg coil) for securing rebar, mesh, and general site fixing applications.

When selecting wall ties, match the length to your cavity width and confirm whether insulation retaining stars are needed. For timber frame builds, the Powertie system requires fixing into structural studs at the specified spacing - always follow the manufacturer's installation requirements and check current building regulation tie patterns for your wall type.
