The demands that are placed on bridge waterproofing with bituminous membranes differ in some respects from those used for roofing. It is essential that the bituminous roofing sheets are connected frictionless with the bridge structure. This is done through a primer (with epoxy resin molding) and a full-faced 1st bitumen waterproofing layer. Also, the asphalt protective layer is homogeneously connected with the bridge sealing.

Bridge waterproofing with polymer bitumen membranes withstand the extreme loads (mechanical, thermal and chemical effects) that are placed on bridge structures permanently.

Therefore, the scope of bridge structures has been extended to parking levels in car parks, underground car parks and tunnels in open construction (waterproofing of the tunnel tray). This has been well-established now for decades protecting building constructions permanently and effectively against damage caused by moisture.

Capping Sheets-Bridge

The capping sheets (top layer) for bridges and parking levels have plastomer bitumen coating. This sort of bitumen is high-temperature-resistant to the installation temperatures of rolling or mastic asphalt.

Intermediate Layer Sheet-Bridge (mopping method)

Intermediate waterproofing layer sheets for bridge and parking level have a elastomer bitumen coating. The processing of these waterproofing sheets is done with a mopping method in which bitumen heat bonded mass is used for submerging. Through this process a 100% homogeneous connection with the ground is produced.

Intermediate Layer Sheet- Bridge (torching method)

Intermediate waterproofing layer sheeet for bridge and parking levels have a elastomer bitumen coating. The processing of these waterproofing sheets is done through a torching method ensuring that it is fully bonded with the ground.
