Water reservoirs are one of the main driving forces of the economy: drinking water supply for the cities, crops irrigation, floods control and electricity production in hydroelectric plants. Construction of dams is a well-known old Spanish tradition. Since Roman times, many infrastructures were built, including important technical milestones like the arch-gravity dam of Almansa, the oldest operative dam in Europe (1584).
Because of this experience, more than a third of operating dams in Spain are over 50 years old. Hence, a strong research and development of products and systems was done to conserve and rehabilitate this important social heritage according to more modern requirements.

2. Waterproofing of upstream face including injection of rubber resin.
3. Preparation of expansion joints between the dam wall and the lower edge of the coating, at the bottom of the upstream face.
