These are two types of work in two different areas but some of the improvement aspects are common to both areas.

Reinstatement interventions in order to guarantee a security system in tunnels (pedestrian road and train) or, in the case of canals, interventions in order to guarantee the correct quantity of water through the system.

For these interventions appropriate materials are used in order to guarantee resistance to natural elements – special nets – strong dowels – chemical components such as resin, hydrowashing, cavity sealing with polyurethan mastic, injections for strengthening vertical masonry structures, improvements with cement coatings, installation or substitution of valves.

These are only a few examples of products and types of work carried out by us in order to guarantee the safety and efficiency of the interventions.
