2. Dry Installation Method Of Natural Stone
Cladding
• Dry installation method
which is also known as
mechanical installation
method uses embedded
metal anchors and ties
for the connection
purpose. The stone
required for this method
must be thick because
the method requires
drilling which could
increase the occurrence
of cracks.

3. Advantages Of Dry Installation Method:
• The dry cladding method is safe and it prevails the stone from falling off for
years.
• This method allow for expansion and contraction of stone in extreme
weather conditions.
• The dry cladding method creates a cleft of around 30 to 45 mm (1”-1.5”) in
between face of the wall and stone covering, providing a layer of air
cushion that acts as a thermal barrier.
• The appearance of stone used in dry cladding work looks spotless and
aesthetically pleasing.
• It is a time saving procedure

4. Advantages Of Dry Installation Method:
• The dry cladding method is safe and chances of stone falling down at a later date is
remote.
• Method allow for expansion and contraction of stone in extreme weather conditions.
• The dry cladding method creates a gap of around 30 to 45 mm in between back wall and
stone lining , providing a layer of air cushion that acts as a thermal barrier.
• The appearance of stone used in dry cladding work looks aesthetically pleasing. The
stone fixed with mortar may change in colour due to absorption of water from back mortar
layer.

5. Disadvantages Of Dry
Installation Method:
There are chances for the occurrence of cracks on
substrate.
It is an expensive method.
Requires perfection and alertness because of the
following
If the holes are not drilled properly then it could waste
material.
While drilling one must be alert otherwise it could be
harmful for you.
It requires high skilled labour

10. Step 2: Site
Preparation
Clean all the dirt from the surface of
the wall.
If the wall is constructed freshly make
sure it is properly dried up and the
surface is not friable so that the pin
could be firmly fixed in the hole
drilled.

11. Step 3:
Installation
Method
Clad Similarly clad the entire wall.
Leave Leave a clear space of at least 2mm between every 2 natural stone.
Place Place the first natural stone and tighten the bolts and pin properly.
Insert Insert the pin in the angle to match the hole in the cladding stone.
Insert Insert the expansion bolt into the hole.
Drill Drill a hole of appropriate depth and thickness according to the size of pin.
Standard dimension of hole can be 80mm – 100mm (3” – 4”)
Start You can start either from the left or the right corner of the wall leaving a
minimum gap of 2mm (0.07”)
Locate Accurately locate the position of the hole

12. 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
.
