Conbextra UW

Formulated anti-wash out, specialist grout for underwater grouting applications.

Description

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 the ‘washing-out’ of the cement phase when placed in
stationary or moving water.

Conbextra UW is a blend of cement and 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 0.3mm.

Uses

Conbextra UW is used for free-flow or pumped grouting
applications underwater or in tidal zones. There will be no
significant ‘wash-out’ of the cement phase. Applications
include bridge columns, quay pillars, concrete piling, slipways
and dams.

Advantages

• No risk of significant ‘wash-out’ of the cement phase when
  placed underwater
• Displaces water effectively
• Gaseous expansion system compensates for shrinkage
  and settlement in the plastic state
• High early and ultimate strength
• Chloride-free
• Pre-packaged, needing only on-site addition of water
