Marine environments can pose significant challenges to construction, repair and maintenance of buildings, structures and civil engineering works, for instance, reservoirs and coastal defence systems.

Significant issues to take into account include:

  • Frequent freeze-thaw cycles in cold climates
  • Frequent wet-dry cycles
  • Long-term immersion in water
  • Tidal flow of water
  • Impacts from waves and other materials such as rocks carried by the waves in marine sites
  • Erosion
  • Salt-water
  • Increased corrosion of steel reinforcement bars, accelerated by salt absorbed by the concrete

While our qualified team assess the work at hand all these variables are taken into account when applicable and more, for such categories as:

  • Water towers
  • Water and sewage treatment works
  • Zoo seal aquaria
  • Reservoirs
  • Coastal Defence and many more.
