A stone wall can be clad with similar constructions as a concrete wall. When attaching the panel, the techniques differ. Natural hard rocks are difficult to work. Soft rocks do not always carry the fairing safely. Specific properties are taken into account by fitting.
mounted or directly attached
In order to change the appearance and beautification of an old stone wall, a cladding can be applied over the entire surface of the stones or fastened with a substructure. For cladding applied directly to the masonry
For both types of installation, the type of stone and the method of construction determine the possible and suitable fixings. For direct cladding such as plastering on the stone surfaces, the joints must be veneered or filled. Primers ensure a uniform absorption of the stones and form a bonding layer.
Simple cladding or reworking
Two versions are possible for mounted cladding:
1. The cladding is attached to a substructure without further processing
2. The cladding itself forms the substructure for further processing
Classic "finished" cladding consists of the materials Wood, prefabricated panels, stone tiles or plates and plastics. Facade panels made of composite materials are also suitable for cladding a stone wall. Alternatively, multipurpose panels can be mounted, which are then drained or plastered.
Types of fastening and substructure systems
In principle, ventilated cladding with a few centimeters distance to the masonry is the structurally "healthiest" choice. To fix wall panels in slab or board form, the substructure must provide the required attachment points. Cross-shaped wooden slats or metal poles fulfill this function. L The slats or poles can be fixed to the stone wall in several ways:
Handrails or anchors are inserted into the joints
- Holes in the stones form dowel holes
- Special glue connects stone surfaces and support frame by spacers
- A grid serves as a screw-on support
- For hard to drill Hard rock is recommended for joint anchoring. Even in dry stone, anchorable waterproof cement mortars can be added later. When drilling into stones, minimum distances to the stone edges are required to minimize the risk of breakage.
Crumbly limestone and sandstones are usually unsuitable for use as well carriers. Here are also free "floating" substructure systems possible. They are anchored in the ground in front of the stone wall with a stable foundation such as a strip foundation. At the top of the wall a conclusion forms the counter bearing.
