On bridge decks, waterproofing systems that use prefabricated asphalt sheets provide uniformity and quality to the deck. They ensure the complete sealing of the deck. In order to achieve this there are different requests:

• Total grip between the waterproof membrane, the support base and the protecting layer.

• The waterproofing system’s capacity to withstand the dynamic action of the vehicles.

• Membrane resistance movements in case of surface’s craks.

• Membrane- protection layers Compatibility.

• Membrane resistance to extension and compaction of the surface.

Composan Puentes y Obra Civil meet all these requirements in every waterproofing systems they perform, that use a prefabricated bituminous or elastomeric layer, a waterproofed membrane (obtained from one or several prefabricated asphalt sheets) and a protection layer.

Waterproofing is important on decks, but is more important on rail boards. Here, a non-successful waterproofing could cause damages, but the necessity of a re-waterproofing could cause more difficulties: traffic can be diverted or closed on a road and a bridge, but a railway closing is much more complicated.

Being aware of this problem, Composan Puentes y Obra Civil requires than the selection of products (of great prestige) and system (the best guarantee of stability and functionality) is accurate and meticulous, and it always use the latest and best options provided by technology.

If waterproofing is important carters boards, much more so is the rail boards. Not so much for the damage suffered structure in the case of an incorrect waterproofing (the same as in the previous case) but by the difficulties of re-waterproofing. A road can always divert to temporarily close to traffic a bridge and proceed to the rehabilitation work on it. But for a railway, closure of a traffic board is much more complicated.

Being aware of this problem Composan Puentes y Obra Civil requires both the selection of products to use (of great prestige) as a system to apply (the highest guarantee of durability and functionality) is as rigorous and demanding, attending the best options that current technology offers.
