Grouted Wall Tie

This type of remedial wall tie has a deformation at each end, which serves to maximise its grip in resin or cementitious grout. The grouted wall tie is well suited to domestic buildings having inconsistent or suspect quality masonry. Whilst this tie has a low material cost, its installation process demands much more time and care.

A hole having a diameter 2-4mm greater than the diameter of the tie is drilled through the near most leaf and into the subsequent leaf to a depth of 60-75mm.

Debris is cleared from the drill holes using a blast of air from a hand pump or from a compressor.

Resin or non-shrink cementitious grout is pumped via an extension nozzle to fill the hole in the remote leaf.

The resin grouted tie is pushed into a resin or grout-filled hole in the remote leaf, its deformed end providing a key to maximise grip.

Resin or non-shrink cementitious grout is pumped around the section of the tie that is located in the near most leaf to set around and key to its deformation. The hole is then made good.
