Case story

Lach Huyen Bridge Work Platforms

Vietnam, Haiphong

More than 27 km of Geotube® units were installed to reclaim the 4.1 km × 26 m work platforms and to construct the 600,000 m³ dredged sediment containment facility for the construction of Lach Huyen Bridge in Vietnam.

The construction methodology needed to overcome soft soil conditions, withstand typhoons, and avoid disruptions to construction activities by the large daily tidal ranges, so that the bridge could be completed within the targeted project duration. Locally available sand was also used to replace rock for the reclamation and containment dike construction to reduce construction costs and time.

Geotube® became a proven solution when the tubes survived a direct hit by Typhoon Kalmaegi during construction in September 2014.
