Adaptation, consolidation and musealisation of cultural heritage

Maintenance, cleaning and clearing of vegetation from gardens and archaeological or heritage sites.

How does the process of adaptation, consolidation and museumisation of heritage take place?

The clearing process basically consists of clearing and adapting the area where an archaeological or cultural heritage site is located. In particular, the bushes and weeds that have grown up (both on the surface of the bushes and inside the trees) are removed. The aim of this preliminary work is to prepare and adapt the area, which will later be consolidated and made suitable. In order to guarantee success with less effort, both economic and human, the vegetation layer to be removed is first cleaned with herbicides and then the existing weeds are pulled up. This work will be carried out by archaeological assistants under the supervision of a technical director, who will document the entire process. The manual nature of the work will ensure the preservation of any structural archaeological remains that may be present in the subsoil. To this end, only tools such as hoes, picks, pickaxes, trowels and pruning shears will be used.

The consolidation of structures with reversible materials, the adaptation of spaces and the design of all types of signage, both to preserve the remains and to socialise them and make them accessible to all types of public.

Conservation and restoration work will be carried out according to reversible criteria and will always be supervised by a technical director. Within the framework of these works, especially in view of the precarious or poor state of the site or part of it, the consolidation of walls, the reconstruction of walls and the adaptation of pavements (where remains exist) will be considered, always depending on the type of structures and materials found and their state of conservation. The degree of consolidation and the layer of salvage that will restore the structures will vary according to the state of conservation of the remains (more or less optimal), their solidity and stability; there will be parameters that will only require a small layer of mortar in the stone joints to prevent water seepage, while others will require a salvage layer of several layers, both to protect the structure and to facilitate future understanding.

The protection of the original structures is achieved by reconstructing the walls with a salvage layer, using as much as possible the same fallen stones from the excavations on the site itself. In order to separate and at the same time demarcate the old and new walls, a PVC mesh was installed to separate the original and new levels, after several tests on other sites and on the recommendation of similar architects specialising in heritage. This element was chosen for its characteristics, which do not alter the structures over time, unlike metal mesh, which is more easily affected and deteriorates. In addition, it is a very flexible material that adapts perfectly to the unevenness and gaps that may remain on the surface of the walls.

The stone structures will be treated using the techniques generally used in this type of archaeological work, consisting of consolidating them with a mortar prepared for this purpose using lime mortar (a mixture of slaked lime, fine sand and water in a ratio of 3 to 1, i.e, (a mixture of slaked lime, fine sand and water in a ratio of 3 to 1, i.e. three parts of sand to one part of lime), as it has good properties in terms of strength, adhesion, flexibility and porosity, and does not visually distort excessively with the original parameters (based on stone bound with mud). In order to further minimise this distortion, an attempt should be made to use the same extreme mortar from the site or surrounding area, previously refined with different sediments to obtain a mortar with a more earthy tone. If necessary, this mortar will be sanded with graphite to give it greater consistency and durability without losing its reversibility, imitating the old mortar. This process includes the consolidation of clay structures (wall linings, chimneys, benches, etc.) to minimise their deterioration and exposure to the elements. In this case, a consolidation treatment can be applied using the necessary chemical elements to guarantee their preservation against the inclemency of the weather. A chemical compound that reacts with the silica in the clay to form a three-dimensional network of silica dots that increase water resistance and repel water.

Finally, the process of museumisation and adaptation of archaeological sites goes through several stages. Firstly, geotextile fabric is laid over the natural rock to prevent the possible growth of weeds. Next, it is possible to install or create elements that facilitate the drainage of rainwater along the façade of the building, taking advantage of the natural slope of the terrain to facilitate the circulation of water and avoid possible stagnation in the interior of the areas. In places where the natural rock has a steeper slope, the lower parts could be filled with small stones if necessary. This will facilitate the circulation of water in the event of rainfall and also bridge the existing steep slopes, making it easier to place the surface gravel. Subsequently, fine gravel will be placed in the interior of the areas, imitating to a certain extent the original paving and facilitating the movement of people or visitors in the different areas of the building. The aim of this operation is to make it easier to move around the building, without forgetting the primary objective of maintaining the stability of the structures and minimising the erosive effects of the weather.

The first phase of this adaptation would be the use of signs and beacons. The first phase of this adaptation would be the implementation of signs and beacons, which would include the placement of a descriptive sign. This panel
