Recommended Repair Procedure
- Breakout and remove all loose material in the area to be repaired, ensuring that spalled concrete is taken back to the reinforcing steel and coated with QED GalZinc. Structurally inspect the reinforcing steel and replace/reinforce as necessary
- Reinstate the profile of the existing structure using either QED’s Microcrete or Ultrapatch as required.
- Prior to inserting the Margel™ 580, mark out the locations to be drilled on the surface of the structure, with respect to the locations of the reinforcing steel to be protected. Ensure a minimum of 2 cartridges per square metre of surface area are installed. Holes should be drilled to a minimum depth of 55mm using a 20mm diameter drill bit. Insert the Margel™ cartridge, using a small piece of backing-rod (25-30mm diameter) to hold in place.
- Infill the hole flush to the profile with QED’s Microcrete.
- Where applicable use QED’s Skimcoat
- Finally apply either a clear or coloured variant of QED’s Anti-carbonation coating to the entire structure.
