Description

Conbextra UW is supplied as a ready to use dry 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 Portland cements, graded fillers and chemical additives. The aggregate grading minimises segregation and bleeding whilst assisting flow characteristics.

Uses

Conbextra UW is a free flow or pumped non-shrink, cementitious grout for use underwater or in tidal zones where “wash out” would be a problem with conventional grouts. Recommended applications include:

•  Stanchion baseplates
•  Bridge columns
•  Quay pillars
•  Concrete piling
•  Slipways

Advantages

•  No risk of significant “wash-out” of cement phase when placed under water
•  Displaces water effectively
•  Gaseous expansion system compensates for shrinkage and settlement in the plastic state
•  High early and ultimate strength
•  Exceptional resistance to freeze thaw – ensures durability
•  Chloride free
•  Prepackaged needing only on-site addition of water
