Product Description

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.

It is a blend of Portland cements, graded fillers and chemical additives. The aggregate grading minimises segregation and bleeding whilst assisting flow characteristics.

  • 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
  • Pre-packaged needing only on-site addition of water
