Introduction to Stone Anchor Fixing Systems

Fixing systems need to accommodate all types of structural substrate whether they are wood walls, concrete walls, block work & masonry walls or steel structures. The following points must be taken into consideration when designing a fixing system for natural stone installation:

  • Stone dimensions
  • Structural wall backing
  • Cavity structure: depth, projection, insulation
  • Application type: horiz/vert joint installation
  • Joint size
  • Height of facade
  • Relevant dynamic loads – wind, seismic, etc.
  • Design criteria of the project
  • Jurisdictional building codes US / Can

Fixing to Various Substrates

Fixing to structural wood framing using lag screws. Insulation is typically within the stud cavity.

Bottom_of_Wall

Fixing to concrete with bolt anchors using expansion bolts. Insulation is cut at each anchoring point.

Bottom_of_Wall_2

Fixing to concrete with bolt anchors using expansion bolts. Insulation is cut at each anchoring point.

Bottom_of_Wall_3

Fixing to sub channel structure supported to load bearing beams. Insulation is cut at each anchoring point.
