Conbextra UW 25kg

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
