Window Lintel Repair Kits | Retrofit helical wire lintel for cracked brickwork

Can Helical Wire Replace Window Lintels? Yes, helical wire can effectively replace traditional window lintels.

By installing a system of four helical wires within the mortar bed joint and bonding them with either Strucsol HS Grout or a high-strength epoxy acrylate resin, you can create a composite girder masonry beam. This approach enhances both the tensile and horizontal shear strength of the masonry, making it a viable alternative to conventional lintels.

Key Considerations

When evaluating this option, it’s essential to understand the specific loads acting on the masonry. In most cases, particularly when structural window frames in cavity walls are replaced with non-structural uPVC frames, the lintel only needs to support the outer leaf of masonry directly above the window opening. If the brickwork is properly coursed, much of the load above the opening is naturally supported through corbel action. As a result, the area requiring lintel support is typically limited to a triangular section of brickwork immediately above the opening.

For solid 9-inch brick walls supported by a brick arch, a helical wire lintel may be necessary to support both the inner and outer leaf of the wall, as well as any floor joists above. In these scenarios, careful attention to design and load calculations is critical.
