Flash Flood Defense

One of the most modern cities of the world — a hub for transportation and business alike — Singapore is also one of the most vulnerable cities when it comes to flood waters. Singapore’s renowned central business district, its airport and container ports all lay less than two meters above sea level. This great city is not only exposed to the rising sea levels predicted by many scientists due to global warming, but also to changing rainfall patterns that have resulted in a series of unprecedented flash floods that began in 2010 and continued through 2013.

For these reasons Singapore real estate owners and managers are leading the way in flood mitigation to make sure that valuable assets stay dry and in business.


Located in the prestigious Raffles Place and Marina Bay precincts in Singapore, Ocean Financial Centre was named “World's Best Commercial High-rise Development” at the 2012 International Property Awards in London. Keppel REIT developed this landmark premium Grade A office building and it is with great pride that Presray’s flood control products were chosen to help protect this iconic building from potential floodwaters.

Defense against floods has become an integral part of new building design in Singapore. The goal is to maintain the aesthetic beauty of a new building by integrating flood barriers into the building’s architecture.

The photos (to the right) show pre and post deployment of FastLogs®. A good example of this is a new hotel (to be named) at 176 Tyrwhitt Road, which incorporates special doorjambs with covers made to blend in with the building’s façade and trim detail. Presray’s patented FastLogs® are easily stacked into place once the jamb covers are removed. The number of logs determines the height of protection. No tools are needed for deployment, which can easily be done by one person. FastLogs® are Presray’s number one selling flood-protection product.
