Cementitious grout for underwater applications

SikaGrout-UW is a ready to use, class A cement-based grout for applications underwater.  The grout, when properly mixed, will have no significant ‘wash out’ of the cement phase.  SikaGrout-UW is a blend of Portland cement, carefully selected and graded aggregates and Sika admixtures enabling it to achieve excellent flow, non wash-out characteristics and high compressive strength.


SikaGrout-UW can be used individually for underwater grouting or as a system in conjunction with Sika Pile Jacket systems or other confinement jacket repair systems for rehabilitation of concrete, steel and timber piles in marine applications.
