It was decided to start the amphitheater restoration work with the restoration of the façade.
An experimental phase on one of the most severely damaged sections, section 49,
would be followed by the restoration of sections 50 to 53.
Level 1: Cleaning of facing stone using very low pressure microabrasion. Verification of the "joints" and of rainwater evacuation.
Level 2: Resurfacing to ensure that rainwater is evacuated effectively--any cavities are filled in that may be responsible for the accumulation of water
Level 3: Removal of any superficial damage. Cracks are examined and analyzed. Attachment of any sheets of stone threatening to fall apart.
Level 4: Removal of any damage in progress. Assessment of the stability of the stone, repairs by attaching sheets with dowels, cracks are filled in or grafts replace old stone with new stone.
Level 5: The stone is too damaged, which threatens the stability of the edifice. Replacing it seems to be indispensable for the preservation of the monument and for maintaining the greatest number of original stones. On a case by case basis, a decision may be made to keep the healthy part of the stone.
