The construction of a wide range of structures including bridge, dam, canal and river defences has driven the need for underwater concrete.
RMX UW is our specialist underwater concrete; designed combining a range of SIKA admixtures to set almost instantly underwater. The concrete is pumped out like ‘squirty cream’ using a concrete pump or tremie pipe and care must be taken to minimise washout and segregation.
- Rapid setting mix
- Strength/density can be adjusted
- For use in still and flowing water conditions
- Minimised washout
- Easily placed either by concrete pump or tremie pipe
- Reduced risk of contaminating waterways
- Conforms to BS 8443
RMX UW concrete can incorporate a proportion of GGBS, a cement replacement material that generates a much lower level of embodied CO2 emissions than ordinary cement, minimising environmental impact.
