Thor Helical manufactures a selection of replacement wall ties for existing buildings. The cavity-ties are ideal for a range of renovation tasks, including wall tie replacement projects, pinning brick arches, and securing rubble-filled walls.
Independent test results show the hammer-in, self-tapping masonry ties conform to EN845-1:2013 and meet UKCA and CE marking conditions when installed into a broad range of common building materials.
The ties work by corkscrewing into brick, block and concrete, delivering a mechanical fix that grips each wall layer. A small pilot hole is required for installation into all masonry substrates apart from aerated concrete.
The unique tying system offers many benefits over alternative helical wall tie systems, the improvement being the subject of three international patents.
- Precise pitch engineering. A novel manufacturing process produces ties to tolerances that traditional production methods cannot achieve. The result delivers a two-start self-tapping helical tie that that cuts highly accurate threads in the building material. The precise interlock connection delivers unequalled product performance.
- Tie configuration. A unique drive-shank formation on one end of the tie eases use, offers safer working conditions and reduces overall system costs.
- Small diameter drive adapter. A setting tool having an axial recess that confines the drive-shank end of the replacement wall ties. The SDS drive-tool enables the tie to be aligned, driven and recessed in one simple process, without using cumbersome, costly and unreliable telescopic tools.
