Renderoc BB is a specially formulated concrete reinstatement mortar designed for bearing pad and structural seat applications. Supplied as a ready-to-use dry powder, it only requires the addition of clean water to produce a high-performance mortar with excellent handling, rapid strength gain, and long-term durability.
Based on Portland cement, graded aggregates, and proprietary chemical additives, Renderoc BB offers a low water demand mix that ensures a strong, durable finish. Its coarse aggregate content provides the textured surface required to effectively support structural bearings.
Key Features:
-
Rapid strength development – ideal for time-sensitive structural reinstatement

-
Aggregate grading conforms to RTA B80 Table B80.3
-
Drying shrinkage meets RTA B80 Table B80.7 requirements
-
No expansive admixtures – maintains dimensional stability in plastic and dry states
-
Non-reactive aggregate – tested for AAR using RTA T363 (Accelerated Mortar Bar Test)
Typical Uses:
-
Bearing pad repair and seat reinstatement in bridges and structural supports
-
Concrete repairs where rough finish and coarse aggregate are required for mechanical performance
-
Infrastructure applications requiring compliance with RTA and AS specifications
