Fosroc provides solutions to strengthen, protect and waterproof a variety of marine installations including wharfs, bridge pilings, locks, desalination conduits and seawalls. In Hong Kong, for example, we work alongside colleagues in the Water Solutions division for the Highways Department on a giant submersible tunnel project along the northern waterfront of the island.

Even in extremes conditions, Fosroc products and solutions protect concrete against water penetration, cracking and other damage, preventing the corrosion of the reinforcing steel.

Our marine solutions include:

  • A range of high performance and technically superior admixtures for concrete
  • A fully integrated range of highly durable waterproofing solutions for below and above ground waterproofing
  • Protection of concrete structure from weathering, abrasion and chloride ingress
  • Precision-engineered grouts to create a complete support for bases and crane rails.
  • A full range of innovative solutions for sealing expansion and construction joints
  • High performance mortars tested to EN 1504, for structural and non-structural repairs
  • Cathodic protection of marine piles
  • Underwater concreting, grouting and repair materials
