Renderoc LA Xtra – High-Performance, Free-Flow, Low-Aggregate Repair Micro-Concrete
Renderoc LA Xtra is an enhanced version of Fosroc’s Renderoc LA, specially engineered with improved flow characteristics, superior shrinkage control, and extended durability for large-volume structural repairs. This high-strength, cementitious micro-concrete is designed for precision pouring or pumping into complex or congested reinforced sections where conventional repair mortars may not be suitable.
Formulated with advanced additives and carefully selected aggregates, Renderoc LA Xtra ensures excellent workability without segregation or bleeding. It exhibits high early and ultimate strength development while minimizing thermal cracking and long-term shrinkage.
Typical applications include repair and reinstatement of large concrete sections in bridges, piers, columns, decks, tunnels, and industrial structures, particularly where access is limited or reinforcement density is high.
Key Benefits:
-
Improved flowability for easy placement and pumping
-
Enhanced shrinkage control reduces cracking risk
