Underwater Concrete

Heidelberg Materials, in partnership with Sika, has developed an innovative underwater concrete specifically designed to allow pouring through water.

Available from all 174 of our static and mobile production plants, this cutting-edge solution has been successfully utilised in prestigious projects such as Leeds Train Station, Canary Wharf, and the Eden Viaduct.

Watertight concrete is essential for installations below the waterline, offering the same hardening time as in dry conditions due to its high density. To ensure optimal performance, it is crucial to minimise disruption during installation to prevent the washout of fines and cement materials, especially in flowing water.

Our waterproof concrete incorporates advanced anti-washout properties to mitigate these risks effectively.

Explore our full range of underwater concrete mixes below.

Suggested applications

The addition of Sika’s UCS pack allows for easier placement of concrete under water. As such, our Underwater Concrete solution can be used for the following applications:

  • Marine construction
  • Bridges - for underwater elements
  • Water industry structures
  • Any project which requires concrete to be used under water

Benefits of Underwater Concrete

  • Rapid setting to avoid tidal washout
  • Improved cohesion under water
  • Superior anti-washout properties
  • Conforms to the requirements of BS 8443

Sustainable concrete solutions

Heidelberg Materials concrete can incorporate a proportion of Regen, a cement replacement material that generates a much lower level of embodied CO2 emissions than ordinary cement, minimising environmental impact. Recycled aggregates can also be incorporated subject to local availability and mix design.
