Formulated anti-wash out specialist grout for underwater grouting applications.
Conbextra UW is supplied as a ready to use powder. The addition of a controlled amount of clean water produces a free flowing grout. The grout exhibits exceptional resistance to 'washing-out' of the cement phase when placed in stationary or moving water. Conbextra UW is a blend of cement, graded fine aggregate and chemical additives which impart controlled expansion, water reduction and non wash-out characteristics. The aggregate grading minimises segregation and bleeding whilst assisting the flow characteristics. Maximum aggregate size for pumping is 0.3 mm.
