Fosroc Conbextra Uw 20kg

Fosroc Conbextra UW is a specially formulated, underwater-grade, shrinkage-compensated, cementitious grout designed for use in static or moving water conditions. Supplied as a ready-to-use dry powder, it requires only the addition of clean water on-site to produce a free-flowing, non-washout grout. Its advanced formulation ensures excellent stability and resistance to segregation and wash-out, even when placed underwater.

Uses

• Underwater grouting for:

  • Bridge columns and piles

  • Marine structures and jetties

  • Sheet piling and underwater anchors

  • Concrete repair and void filling below waterline

Key Features and Benefits

• Non-washout formulation – prevents loss of cement phase during underwater placement

• Effectively displaces water for complete grout contact

• Gaseous expansion system – compensates for plastic shrinkage and settlement

• High early and long-term compressive strength

• Chloride-free – safe for use with reinforced concrete

• Pre-blended – requires only water for consistent, easy on-site use

• Fine aggregate grading (max 0.3mm) – enhances flow, minimises segregation and bleeding

• Suitable for pouring or pumping into underwater voids
