CemTie
Grouted stainless steel tie for stabilising solid masonry
CemTie is the solution to the problem of stabilising solid masonry. Cut from shorter lengths of HeliBar, CemTies provide a fully grouted reinforcement tie suitable for use in a variety of situations, including: bonding wall junctions, restraining separated or leaning walls, stabilising masonry arches and securing bulging solid or rubble-filled walls.
CemTie installation comprises the bonding of cut lengths of HeliBar into clearance holes drilled directly into the affected masonry with HeliBond cementitious grout.
Applications
- Stabilising solid or rubble-filled walls
- Lintel repairs
- Securing multi-layer brick rings in bridges, tunnels and arches
- Reconnecting separated internal and external building walls
- Securing delaminated masonry
- Repairing and securing parapets, cornices and decorative fascias
Features
- Austenitic stainless steel tie up to 1200mm long as standard
- Stress-free by accommodating normal structural movement
Benefits
- Quick and easy installation
- Tie and grout installed simultaneously
- Ideal for overhead installations
- Highly cost-effective masonry repair technique
- Much quicker and simpler than alternative methods
- Minimal disturbance to building fabric for sympathetic repairs
- CemTie plus HeliBond grout produces great tensile strength while retaining rotational flexibility
Bonding Agent
- HeliBond cementitious grout

Installation
Example Application: Repairing a rubble-filled wall using CemTies (Reference: ANZ-RF01)
-
Drill a clearance hole (typically 14-16mm diameter) to the required depth and flush clean.
-
Wind the CemTie fully into the grout-filled pinning nozzle of the pointing gun and insert the nozzle to the back of the hole. (Alternatively, fill the hole with grout and then wind the tie into the grout-filled hole.)
-
Pump the pointing gun to inject the grout while slowly withdrawing the nozzle. The CemTie will be carried out with the HeliBond grout as it is forced through the nozzle.
-
Back pressure will help push the nozzle out of hole to leave a fully grouted tie.
Caution: Always locate, identify and isolate any electrical, water or gas services which may be present in the wall or the wall cavities and can pose a safety risk before drilling or cutting. Always take the necessary safety precautions. Use electrical safety gloves and wear appropriate footwear and eyewear. OHS Reference: Helifix Remedial Wall and Pinning Safe Installation Guide.
