Facility maintenance is carried out by specialised staff which guarantees optimal functioning and lengthens their lifespan. In addition we carry out, by our own means, hydraulic works (water supply and sanitation, pumps…) and we can coordinate any other type of facility under the supervision of a technician responsible for each area. We can give advice about the use of new technologies and the appropriate materials for each facility. Proper maintenance will lengthen the facilities’ lifespan, making them more cost-effective for the company that depends on them. We also bear in mind the energy efficiency of the facilities with the intention of improving every project.
