The drywall is a typical construction system made ​​up of stone elements properly shaped and fastened together without the use of a binder. Throughout the centuries this building technique has been used by many people, scattered in different continents, with works of different size, such as pyramids in Sardinia, as well as for the ancient walls of the city or the boundaries of places. Based on the characteristics and complexity of these artifacts, the stones could be placed with the edges perfectly coincident, or with sides just outlined.

Nowadays this type of construction has no use of structural features but is relegated to purely aesthetic. An example of this activity is present in the Province in part goes back to an old tradition marked by rural zoning of agricultural land in a web of dry stone walls in places demarcation of the different properties. The most frequent examples of using this type of building relate to the situations naturalistic gardens with ornamental composition of terraces, seating, pathways boundaries, which are a magnificent demonstration in the park of the Castle of Conjugation in Ragusa, built in the style of Garden Landscape. The concept takes an artistic movement born in England between 1750 and 1790, which is the fall of the antithesis between traditional garden and Architecture on the one hand, Natural landscape and on the other, that is drawn between nature and wild.


Besides this stylistic model, the typical processing and position of the stone has been widely used for the enclosure walls and in combination with other materials such as iron railings, covers in terracotta, concrete elements face view, etc. It is evident that, the association with elements of a different nature, lose the characteristic of originality over that encroaching, in certain cases, in architectural structures of taste kitch. Aside this assessment, the type of construction of dry stone walls, can be used to cover masonry walls of buildings. In this case, you use the ashlar stone mandolin and composing in various sizes, and placing it directly with a layer of mortar on the masonry. This procedure, which sortie l ‘ effect of drywall, has the objective limits and that relate to the weight of the coating. Indeed, since for machining requirements is not possible to use elements with thicknesses less than cm 10/15, it is evident l ‘ opportunity to raise the curtain wall directly on the plan of campaign.
