The company specializes in the implementation of continuous paving, Arteco del Vallés, has carried out the work

The project of reimpermeabilización of the outer covering of the supermarket Mercadona in Figueres (Girona) needed a waterproof and stretchy system that solved all the problems of water leaks that were suffering so far. The technicians of Sika and Vallés Arteco noted that, without rain, water leaks were produced from the deck to the lower floor, which is the commercial surface itself.

Also, there were also areas in which the lining was not attached to the support, and once withdrawn, found how the water was encharcated, and subsequently filtered. In addition, the entire surface of the spaces was patched, very impaired and it needed a comprehensive reimpermeabilización. Arteco del Vallés, specialized in the implementation of continuous paving, has finally solved all the problems that Mercadona was having for more than half a year through the application of elastic and waterproof system of Sika: the Car Park Deck system. This solution stands out for the great adherence support; the good capacity of capacitance of cracks even at low temperatures (- 20 ° C); the waterproof; and it is mechanically resistant when saturated with arid.

Aspect of the soil of the Figueres Mercadona before its renovation with the Car Park Deck of Sika system.

The application of the primer epoxy of two components, low viscosity with great power of penetration and adhesion, favours the Union between the concrete and materials apply. The layer based on polyurethane, which uses the Sikafloor-350 N Elastic product, serves to waterproof the entire surface of the deck and then apply a layer of taxiway, which provides the necessary mechanical resistance systemto support the transit of vehicles. This layer of rolling is performed by applying Sikafloor-355 N Elastic amassed with barren quartz, Sikadur-502, and later I sprinkling of arid until saturation with a larger grain size quartz sand as Sikadur-510. As a final layer of sealing, uses a polyurethane coating of two components, with good mechanical and chemical behaviour of easy application and great stability to scratching, due to his tenacity and ultraviolet radiation.

The spaces to the outside has an approximate area of 1,000-1,200 square meters and includes a ramp of exit of the same, which also had to deal with. The implementation of this ramp does not imply additional problem, given that the layer of Raceway which is applied on top of the waterproofing, avoids that the product pick up, and can be placed both horizontally and on surfaces with a slope.

The application could perform in a time record, including the work of elimination of the existing pavement, using only five days, for its complete finish.
