Precast pieces of concrete used mainly for civil work. They are made of extra hard double layer and concrete cores with a resistance to compression superior to 35 N/mm, available in several formats to be adapted to the different needs of work. Elaborated in conformity with UNE EN 1340:2004, they possess the European compulsory guarantee of safety (CE). The whole range belongs to the same resistant family, with a typical resistance to flexure of 6N/mm advisable for conditions of intensive usage (for instance roads or motorways).

Pipes of reinforced or non reinforced concrete, with elastic rubber joint, for water conductions without pressure, used both in Civil Work and in Irrigations. Elaborated in conformity with UNE EN 1916:2003, they possess the European compulsory guarantee of safety (CE).

The riprap of concrete substitutes the natural stone in work. With this piece we manage to cover collectors, dams and etc, in a short time and with absolute safety of placement, logically at very competitive prices. The piece has some studied and calculated dimensions, which for its own weight and its geometry turns into a very stable piece to be placed; since it works as a jigsaw and it is practically impossible to dismantle a single piece. Alternately, it has some bulges with a specific shape in its top part, which avoids slides and generates turbulences in the water, consequently stopping the speed of the water if it is required. This product is Patented by Gilva, S.A.

CANALS Precast Sections for the flow of water. These are specially designed to transport "seen waters" and to give solutions in works that need the incorporation of an aqueduct. They are made of modules 5metres in length. Depending on the anticipated volume of flow, the most suitable model will be chosen.   CATCHPITS It is used when the canals are not manageable because of their enormous dimensions. They have a changeable volume of flow depending on the floor width. It manipulation and assembly is very swift and simple. It presents excellent long-term results, as can be seen in previous works. Completed works: Imperial Canal of Aragon, Civan´s Canal, Canal of Pinyana, small canals for Hydraulic work. el of Civan, Channel of Pinyana, and flumes for hydraulic work among many others.

Mainly we make two different types of distribution boxes. The first type for irrigation, whose mouths are adapted perfectly to our mouth bell pipes up to 120 cm diameter. The second type is used as telephonic station: Adapting to the formats that the customers request us.
