All remedial wall tie installation must be tested. Here, our technicians demonstrate the on site random testing of Helifix remedial cavity wall ties. The system is based on Helifix remedial wall ties because these are perfect for this application. Here they are resin bonded in the exposed inner leaf. This is due to the outer skin of the stone wall collapsing in high winds.

The new system is installed and then random ties are cut back for tension testing. The ties are in effect pulled to 1100N using a calibrated tension rig. Note the corks placed on the sharpened ends of the ties – this is to protect the bricklayers from harm when the outer skin is re-built. They simply remove the corks as work proceeds.
