Pavement repair of 2 freezing tunnels

For the repair of the pavements of these 2 -45º freezing tunnels, PROXTREM, PROMSA’s specific concrete especially for pavements subjected to very low temperature conditions and freeze-thaw cycles, was used.

The 2 tunnels with a surface area of 75m2 each, the existing pavement was previously rehabilitated as it had cracked quite badly. Once cleaned up, the PROXTREM pavement was applied by pump with a thickness of about 15-20cm and without joints due to the use of structural polymeric fibres.

In this case, the PROXTREM was coloured in red with a fine finish (in accordance with the floor of the meat cutting plant) at the customer’s request.

The work was carried out in the Osona region (Barcelona province) from Promsa’s plant in Les Masies de Voltregà, near Vic.
