RMX UW

Underwater Concrete

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.
