Black Sandstone Steps and Travertine
Black sandstone steps and travertine are sedimentary rocks with:
Low strength
High water absorption
Poor weather resistance
These characteristics make them less ideal for stone curtain wall panels. However, their unique texture, color, and style make them a favorite choice among architects.
Application in Stone Curtain Walls:
For glue-injected board seams:
Waterproofing should only be applied to the outer surface of the stone slab.
For open board seams:
The stone slab should be waterproofed on all six sides.
Due to their physical properties, careful selection of these stone panels is crucial to ensuring maximum safety in construction.
