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 that may be used 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.
The CemTie system involves bonding cut lengths of HeliBar into clearance holes drilled directly into the affected masonry with high performance HeliBond 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
- Grade 316 stainless steel tie up to 1m long as standard.
- Wide range of applications.
- Stress-free by accommodating normal structural movement.
- Quick and easy installation.
- Tie and grout installed simultaneously.
- Ideal for overhead installations.
BENEFITS
- 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.

INSTALLATION
Example Application
-
Drill a clearance hole (typically 14-16mm diameter) to the required depth and flush clean.
-
Push 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.
