The Helifix Terracotta Tie secures fragile terracotta facings and delicate decorations and features which have become loose or are suffering from stress fractures.
1. Drill a small pilot hole through the terracotta and into the backup material using a rotary percussion drill (3-jaw-chuck- type).
2. Load the tie into the insertion tool fitted to an electric hammer drill (SDS type).
3. The tie is power driven into position (with SDS hammer drill) until the outer end of the tie is automatically recessed below the face of the terracotta. Make good the entry hole with matching materials. In thin walled terracotta, the tie may need to be left flush with the surface.
