The presence of other sulfates such as sodium, and magnesium, contributed to its deterioration, and the action of important magnesium chloride, sea water is to be used at certain times of execution.

Actions: Among the initial issues are: slabs supported on four edges, and two business addresses, whose main reinforcement in two directions, the steel used is 12 mm, not appreciated if the whole lower reaches reinforcement supports, if there any part where the steel is cut or have bayonets as landslides are occurring at third light. The bars can be saved by cleaning it with metal wire brushes, and there is presence of poor quality concrete stones appreciate settled on the lower level due to lack of fixed large divestitures. Arrows are not present, or bends in the existing slabs, nor bending moment, or failure supports.

The roof deck enrajonado based, and soldering with very bad state of conservation, flooding in some areas, absence of primers and pending for disposal. The boards have between racillas erosion problems, and problems of waterproofing parapet walls, and no rain gutter mesh protection.

So you must submit to demolish all the enrajonado and soldering, as this cause has affected all the structural elements.

Rehabilitation: Is necessary to remove all coatings that are loose or detached from the whole area of the slab which is porous and cleaning the steel wire brush and hammer (in our case does not exceed 20% or slabs, or the stairs.)

Using on the roofs of slabs balconaduras antacid antacid and mortar joints.

Must get up all the cover and clean the concrete, level it, put a layer of felt, a layer of asphalt impregnated felt, place a layer of asphalt mortar, mortar place racilla, and then place the racilla with a good melt.

Loose concrete should be covered with chicken mesh and give such berths or steel welding in sight, and then apply a layer of products like SIKA, oy applying a mortar with a projection (genito-shatconcrete), large density, using resistant cement and is not possible to use soluble glass, applying hot or cold with a brush in several layers on the concrete surface to be protected.
