Masonry ties are 450mm long drive pins that are exclusively available from Thorhelical. The patented stainless steel Airtwist ties corkscrew into brick, block, concrete and masonry when driven into an undersized pilot bore.
The helical ties are ideal for tying solid façade walls back to party walls without the need for grout. Simply drill the pilot holes at 300mm vertical centres. This dry-pinning system is at least 50% cheaper in material cost to traditional resin or cement grouted fixings and at least 10 times as fast to install.
Use these versatile self-tapping fixings to pin up brick arches, tie masonry soldier course lintels and pin down coping stones on parapet walls. The drive pins come in a kits containing:
- Pack of long masonry ties – 9mm x 450mm Ties – Select from a pack of 18 or 36
- A long series SDS tungsten carbide masonry drill bit for use in forming the pilot holes
- A remedial wall tie setting tool that fits an SDS drill for use in hammering the tie into pre-piloted masonry
Try using the long masonry ties as dry-fixed dowels in existing floor slabs prior to the pour of adjacent concrete slabs.
