Dry walls are made of stones of various types and sizes, laid without mortar binding them or bound only in certain places.: these stones should have at least two flat surfaces (supporting), approximately parallel to each other. The third face should be perpendicular to them, which allows you to create an even plane of the face of the wall. For the construction of dry walls, rounded stones of glacial and river origin and unsorted crushed stone are not suitable..
Dry walls It is usually made of untreated stones, usually split in layers. Stone for the construction of a dry wall can also be processed. The machining can apply to the shape of the solid and the surface of the side that forms the face. After treatment, the stone can have the following types of surfaces: raw (natural break), split (layered), chair (traces of smaller chipping with sharp tools), grated (leveled with tools with intermeshing blades), chiseled (fine furrows after leveling with chisels), ribbed, sawn, ground etc..

Building a dry wall requires adherence to the principle of proper stone binding, by placing them with an appropriate offset in relation to the stones of the lower layer. This prevents the formation of vertical joints in the wall. According to this rule, flat stones should not be placed vertically. In order to secure. the surface of the low wall in front of, water running down its outer surface, all stones should be placed with a slight slope towards the wall.
