Protecting and Extending the Life of Bridges

Hundreds of thousands of bridges throughout the world are under constant attack from the destructive effects of moisture and chloride-induced corrosion. Left unprotected, concrete cracks and spalls, allowing moisture ingress into the bridge structure and decking. This triggers a downward spiral of oxidizing and expanding steel reinforcement, leading to larger cracks, more spalling, and ultimately, expensive remediation and a shortened lifespan. Xypex Crystalline Technology stands up to the relentless effects of freeze-thaw cycles, de-icing chemicals and sulfide attacks in saltwater and freshwater environments throughout the world.

Specified for waterproofing and protection of new bridges and for rehabilitation of existing structures, Xypex protects and extends the life of concrete bridges of all types in every climate.

Rehabilitation of Road Bridge over Railway

During rehabilitation of the main bridge concrete structures there was used Xypex Admix C-1000NF as a protection against negative effects caused by stray voltage. Xypex was used as dosage 2,0 kg/m3. Total usage was 1040 kg.

Shenyang Changbal Island Sanhao Bridge

Shenyang, Liaoning Province, China

Shenyang Sanhao Bridge, the world’s first steel arch tower cable-stayed bridge, was designed by Dr. Deng Wenzhong, a world-renowned bridge expert. The bridge’s novel design and overall structure has won numerous awards. The steel arch tower is shaped like a lily petal, a visual that has become popularly called ‘the butterfly wings’, as they appear to spread over the Hun River. Xypex Concentrate was used to waterproof and protect approximately 3,000 m2 of the bridge deck.

Wuhan Yangluo Yangtze River Bridge

Wuhan, Hubei Province, China

This bridge is the world’s eighth largest suspension bridge. Groundwater penetration into the south anchor foundation was a primary construction concern, especially for the foundation pits and continuous walls. Both depth and high-water pressure made waterproofing extremely difficult. Applied to the front and rear anchor chambers, Xypex successfully waterproofed, protected and enhanced the long-term durability of this structure.

Chishi Bridge

Yizhang County, China

Xypex applications thus began in April of 2016, with Xypex Concentrate being applied within the interior of the affected box girder, areas of the bridge deck, Pylon P6 and various related concrete components. Through strict process management and control during the treatment of approximately 10,000 square meters of internal and external surfaces, the application of Xypex proved a complete success, ensuring the ‘healing’ of a residual of cracks as well as the restoration of integrity and durability throughout the stress-impacted concretes.

Rod el Farag Axis Bridge

Cairo, Egypt

More than one million cubic meters of concrete was used to build the bridge, which was used in the bridge decking, girders, and six 92 m (302 ft) tall concrete towers that support 160 steel support cables. One of the key challenges for the bridge designers was how to adequately protect the critical concrete structures from the effects of air pollution and the moist riverine environment.
