The Marina Coastal Expressway, which opened in 2013, is part of Singapore's motorway network. Construction of the tunnel, which is approximately five kilometres long, took a total of five years. For around half a kilometre, parts of the tunnel are below sea level.

To guarantee a reliable and above all long-lasting seal, our partner, J&P Building Systems Singapore, supplied our tried-and-tested PENTAFLEX KB® seam sheets.
