Fishing is critical to the economy of Sri Lanka’s coastal villages. Therefore, the construction of the new Dikkowita fishery harbor, South East Asia’s largest, was such an important endeavor.
The Dikkowita fishery port basin spans approximately one kilometer, with two breakwaters and a quay well. The harbor also includes an office building, a fish market, a fishnet repair workshop, a ship chandlery, crew quarters, a ship repair slip and a wastewater treatment plant.
Valued at $44 million, the harbor is located about 10 kilometers north of the capital city of Colombo, and close to the airport and the new central fish market It was designed to accomodate 125 ft. fishing vessels and to facilitate the anchorage for 150 one-day trawlers and 20 multi-day trawlers by establishing 11nos of jetties.
LafargeHolcim provides the right mix for an important port project
Finding the right concrete mix design proved challenging, requiring several trials to meet the project’s specific high early strength requirements. Over the course of the two-year project, LafargeHolcim delivered concrete solutions to cast more than 6,000 Xblocs that were used to construct the harbor’s breakwaters designed by Delta Marine Consultants.
The Xblocs provide a uniquely stable interlocking structure, and were produced using significantly less concrete than traditional methods. Thanks to LafargeHolcim’s special concrete mix, our partners were able achieved the required production rate of Xblocs, i.e two Xblocs per mould per day.
Since its completion in 2011, the Dikkowita fishing harbor has provided fisherman with direct access to the sea and high standard facilities, replacing facilities located along the Negombo lagoon. Local fishermen therefore no longer have to navigate the Hamilton canal to access open waters, and can now take advantage of the harbor’s strategically important location to spur trade and economic growth.
