The document discusses stone cladding for building facades. It recommends using corrosion-resistant materials for anchors and fixings. For facade heights, it recommends less than 28m if joints are mortared and less than 18m if not. It specifies diameters and materials for corrosion-resistant ties between 5-6mm depending on stone thickness. It also recommends a minimum 2cm ventilated air space between the stone cladding and building support. Anchors can be fixed in the support by embedding in mortar or with stainless steel wedges compatible with the tie material.

1. STONE CLADDING
Lecture by: Ar. Navdeep shukla

2. All external anchors, dowels and fixings should be of stainless steel or other
corrosion resistant materials. Any metal dowels and fixings securing the
cladding panels should be suitable, permanent and adequately protected
from corrosion.
Height of the façade must be less than 28 m if the joints are filled with mortar
and less than 18 m if the joints are not filled
TIES
Corrosion resistant wire (copper,
brass ,stainless steel or zintane)
DIAMETERS
-5mm for slabs 30 to 40mm thick
-6mm for slabs graeter than 40 mm
thick

3. AIR SPACE
The distance between the back of the stone and the
reference plane of the support or the insulation must be
greater than equal to 2cm
FIXING THE ANCHOR IN THE SUPPORT
-either by embedding the anchor with cement mortar
-or by mechanical means using stainless steel wedge –type compatible
with the metal of the tie

7. cladding
ties
Wall cladding consisting of stone slabs attached to a stable
support by ties, these ties are coated in a plug of mortar ,in a
ventilated air space created between the cladding and the support
