Guidelines for Sandstone Patio and Travertine in Curtain Wall Engineering

When using sandstone or travertine for curtain wall engineering, the stone must first pass basic material property tests to ensure it meets the necessary conditions. Only then can it be processed into panel plates for construction.

Basic Requirements for Sandstone Patio Panels

1. Panel Thickness

• The flexural strength of a thicker slab is generally lower than a thinner one. However, because the load-bearing capacity increases proportionally to the square of thickness, thicker slabs are still more durable.
• Minimum thickness requirements based on flexural strength (fk):
  • fk ≥ 8.0 MPa → Minimum thickness: 35mm
  • 4.0 ≤ fk < 8.0 MPa → Minimum thickness: 40mm
• The standard deviation method should be used to determine the minimum flexural strength.
• Thickness tolerance: +2mm / -0mm (no negative deviation allowed).

2. Panel Size

• Due to the low strength of sandstone and travertine, panel size should not exceed 1.0m².
• Avoid using long, slender slabs, as they are prone to breakage during transport and installation.
• Best side ratio: 1:2, but should not exceed 1:3.

3. Surface Treatment

• Waterproofing is essential since sandstone and travertine absorb water.
• Use water-repellent coatings with organic fluorine or silicone-based paints to reduce water absorption below 1%.
• Waterproofing application:
  • For glued board seams → Waterproof only the outer surface.
  • For open board seams → Waterproof all six sides.
• Large or excessive holes in travertine should be sealed before use.
• Apply waterproof treatment only after all grooves and holes have been machined, cleaned, and dried.

4. Back Composite Layer

• Sandstone and travertine are fragile and not highly weather-resistant.
• To prevent breakage and ensure safety, apply a back layer of fiberglass cloth or composite materials.

Handling Special Cases

In some cases, unqualified stone is purchased and installed due to lack of technical assessment. This poses serious risks.

For example, an Australian yellow sandstone was used for a 40m-high, 7000m² curtain wall without proper testing. Many slabs broke during transportation and were still installed after being bonded with epoxy glue. Eventually, the installed slabs cracked and tests showed:

• Minimum flexural strength = 2N/mm² (far below standard).
• Water absorption = like a red brick (excessively high).
• The stone did not meet curtain wall safety requirements.

To prevent catastrophe, the following remedial measures were taken:
✅ Remove all improperly installed panels.
✅ Eliminate all loose, damaged, or epoxy-glued slabs.
✅ Apply six-sided waterproof coating.
✅ Reinforce slabs with a 1mm thick fiberglass-resin composite layer.
✅ Attach aluminum framing to each slab with screws.
✅ Modify long slabs for better support & add aluminum pillars.
✅ Ongoing inspection for future cracks or damage.

These corrective actions significantly increased costs but were necessary to ensure safety.

Conclusion

When using sandstone patio panels and travertine in curtain walls, safety must always come first. Key steps include:
🔹 Conduct thorough technical feasibility studies before selecting stone.
🔹 Understand material properties and limitations.
🔹 Minimize panel sizes & avoid long slabs.
🔹 Use machinery for precise hole & groove cutting.
🔹 Ensure proper transport & installation techniques.
🔹 Apply waterproofing & reinforcement where needed.

Preventative measures are always better than costly repairs. Proper planning and adherence to safety standards will avoid major risks and ensure long-term structural integrity.
