Coatings or claddings of natural stone are elements that have a decorative function or isolation, but not a bearing function.

Traditional masonry has been increasingly expanded with the evolution of fastening techniques.

Facade installation with mortar and tile adhesive is critical work of professionals, as they must determine the thickness of the cladding on the climate to support and take into account the use of stainless steel anchors.


Natural stone is used in many buildings to line the exterior walls, giving them a finished hardness and quality.

The outer cladding enhances the visible image of the building and provides a number of qualities that relate to sobriety, elegance and durability.


There are three fundamental aspects to be taken into account when deciding upon the outer covering of the building with stone facing. First, the choice of material, which should be rock hard and resistant to the action of water, wind and environmental pollutants to which it is exposed.


It preferably has a polished finish to impede the accumulation of scar tissue on the surface of dirt, which also serve to support the action of microorganisms that have just lichens and fissuring or destroying the stone.



The second aspect to consider is the joining or supporting of front plates, which can be done by mortars, resin-based or anchors or metal studs for attachment to the factories or walls.



Particularly important is the case with parts located at the front of the floor and on the ledges of balconies and terraces. In them, the danger of loss is compounded by the oxidation of the frames or bands perimeter of the floor or the improper design of the waterproofing or isolation of these bodies flown.

Finally, it should be considered that the materials expand and shrink due to the action of heat or cold, so it is never advisable to have the pieces too close together, must always leave a gap between them so they can absorb small variations of size.



If the tiles or flooring panels vertically outwardly exceed 9 meters it is recommended to have an interim board, preferably coinciding with the bottom line of the floor or deck plant. The vertical joints should coincide with the holes, and in no case be located at distances of greater than 6 meters.

Hitting the choice of cladding material, conveniently and regularly hold operations required maintenance and upkeep will ensure durability and safety for building users and pedestrians.


Placing without inner tubes

This is commonly used in low-rise cloth, not more than 5 or 6 m, although it is advisable not to exceed 3 m.

Between the cladding and support, a space of about 3 cm is left, which is filled with mortar.

As a safety measure, staples should be used. These are received with mortar and anchored to the wall of brick or concrete.

Particular attention should be paid to the nature of the support, because if this is concrete, it is enough to create a rough surface (pitting) and for adequate adhesion.

This type of veneer does not ventilate the stone, so its use should be limited to special situations.

The inner tube placement with

Establishing an air chamber between the cladding and the wall of the building which makes a very good ventilation of the stone.

The camera typically has a minimum width of two and a half times the thickness of the plate.

Anchors should preferably be of stainless steel, galvanized elements regardless of whose durability is much smaller.

In contaminated areas and coastal areas, this recommendation is mandatory.

For the choice of a model of anchoring one must follow the instructions of the manufacturer, who usually finds the right information through trade catalogs.


The natural stone tile

Where the cladding is carried out without a cavity thickness of the pieces is generally lower than when there is air chamber.

Calculating the thickness can be performed from wind efforts lead to different moments between the anchor points.

This is a theoretical thickness which in practice is normally exceeded for reasons of safety, and concluded practice in most of the rock, using a thickness of 3 cm, when the anchor bolt is.

Also the thickness may be increased, for reasons of durability, frost or contaminated areas, where the material degrades more easily.
