Applications
Stainless steel helical pin for providing a strong mechanical key when patch repairing reinforced concrete
Additional Advice
- Pin spacing and position may be varied to suit site conditions
- Pins are to be installed approx. 50mm from the edge of the patched area
- Intermediate pins should be at 150-200mm centres. Extra pins may be used at the discretion of the site management or the engineer in charge
- Pins should be applied at not less than two pins per patch
Installation
Step 1.
Remove all loose concrete from the area to be patched. Hammer tap the area to establish if any hollows are present and break back to sound concrete. Remove any dust and debris with a stiff wire brush. Clean and treat any exposed embedded steel rebar with a suitable epoxy coating.
Step 2.
Drill pilot holes, vertically or at an angle of up to 45°, to the correct diameter and spacing into the concrete (using an SDS rotary hammer drill).
Step 3.
Fit the Helifix PatchPin support tool over the drill bit and insert the Helifix PatchPin into the tool. Install the Helifix PatchPin into the pilot hole with the SDS rotary hammer drill set to hammer only. Ensure that the outer end of the pin will be below the face of the concrete patch – the pin can be bent, if required
Step 4.
Apply the patching mortar, as required, in accordance with the Manufacturer’s instructions. Fill all gaps and make good the surface.
