Description

A free flowing 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, with the aggregate grading minimizing segregation and bleeding whilst assisting flow characteristics. It conforms to the requirements of BS EN 1504-3 Class R4 and is suitable for stanchion base plates, bridge columns, quay pillars, concrete piling and slipway applications.

Features:

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