Marine Structures

Proven Protection for Marine Structures

The destructive effects of water and chloride-induced corrosion on reinforced concrete are well-known in the marine world. Marine structures are particularly vulnerable to deterioration when cracks occur. Once the moisture and chlorides reach the steel reinforcement inside the structure, it results in an expansive oxidation cycle, which leads to more cracking and spalling. Without proper protection, the structural integrity of a marine structure can quickly be compromised. Freeze/thaw cycles and extreme weather conditions further accelerate the deterioration process.

That’s why it is important to protect marine structures with waterproofing technology from Xypex. With proven results from marine structures in all types of climates and marine conditions around the world, Xypex Crystalline Technology keeps moisture and chlorides from reaching the reinforcement, extending the life of marine structures.

Lafarge Cement Plant, Volos

Volos, Greece

For this project, Xypex Concentrate was applied in a single layer over 11,200 m2 of surface. With the Xypex Concentrate coating in place, both the existing and new concrete in the piers and girders have reduced chloride permeability resulting in extended time to corrosion and increasing the service life of the structure.

Julian B. Lane Park Expansion

City of Tampa, Florida, USA

This 23-acre expansion of the Julian B. Lane recreation center is a $35 million project in the heart of Tampa – located across the river from the Tampa Bay Riverwalk. Xypex Admix C-1000 NF was used to provide permanent waterproofing and chemical protection of chlorides to the new boat house structure. This project is located next to the river where a membrane application was not an option. Xypex Concentrate and Patch’n Plug were also used for joint and tie hole detail. Xypex was selected to provide sustainability and durability to approximately 2,000 cubic meters of concrete throughout the project. 

Nakilat Ship Repair Yard Phase 5 - Caisson & Quay Area

Ras Laffan, Qatar

Royal Haskoning DHV specified Xypex crystalline products to protect deteriorated concrete in the caisson and quay walls. Before initiating the Xypex coating, all defective concrete areas were repaired by the Xypex Concentrate and Patch’n Plug Dry-Pac system. All internal chambers of the caisson went through water tightness tests and were handed over for operation in harsh marine environment.

Nakilat Ship Repair Yard Phase 5 - Dry Dock and Shipyard

Ras Laffan, Qatar

Royal Haskoning DHV specified the Xypex coating system to protect the concrete structure and enhance durability from the harsh marine environment. The structure is approximately 20 meters below ground level and under severe hydrostatic pressure as well as exposure to severe chloride attack and high salinity. The two-coat application of Xypex Concentrate was initiated after repairing the defective concrete with the Dry-Pac system.

New Hamad Port Project at Qatar

The New Hamad Port project in Qatar is one of the world’s largest ongoing Green Development. The project is located south of Dohan, with a 26.5 square kilometer span and a value of 7.4 billon USD. Xypex was selected by Royal Haskoning DHV and Worley Parsons to provide protection and durability to exposed concrete terminals, deck areas and quay walls. Xypex was used to repair all cracks over 0.2 mm with a Xypex Concentrate and Patch’n Plug solution on the exposed concrete deck areas. For durability and sustainability of the concrete terminal decks on extremely harsh marine environment, Xypex Concentrate was coated throughout the 11 terminal deck areas. Around 90 tons of Xypex Concentrate was used to protect the concrete and enhance durability.
