FOSROC RENDEROC RGL — Flowing Repair Micro Concrete for Large Section Structural Concrete Restoration (25 kg)

Large section concrete repairs present challenges that smaller patch repairs do not. When the repair volume is significant — a heavily honeycombed column base, a major section loss on a bridge pier, a large spalled area on an industrial structure support — the repair material needs to be genuinely flowable enough to fill the full formed space without vibration, reach confined corners and reinforcement zones without leaving voids, and deliver consistent compressive strength throughout the repair volume rather than just at accessible surfaces.

FOSROC RENDEROC RGL from Fosroc Chemicals India Pvt. Ltd. is a flowing repair micro concrete engineered for large section structural concrete restoration using formed pour techniques. The flowing consistency of RGL allows it to be poured into formwork around damaged structural elements and flow under its own weight to fill the repair space completely — reaching behind reinforcement bars, filling honeycombed zones, and making full contact with the prepared substrate throughout the repair volume without requiring mechanical consolidation that could disturb the formwork or reinforcement.

The polymer-modified cementitious formulation delivers high compressive strength on curing, strong adhesion to the existing concrete substrate, and low shrinkage to prevent debonding at the repair interface — ensuring the restored section performs as a monolithic unit with the parent concrete under structural load. The dense, low-permeability cured matrix provides durable protection against the carbonation and chloride ingress that caused the original deterioration.

For structural repair and rehabilitation contractors working on large section restoration of columns, beams, bridge piers, retaining walls, industrial structure supports, and any reinforced concrete element requiring a high-volume formed pour repair — FOSROC RENDEROC RGL delivers the flowing repair micro concrete performance that complete, void-free large section restoration demands.

A construction chemical repair solution from Fosroc for large section concrete restoration where flow, fill and strength must all be delivered in a single material — RENDEROC RGL is the flowing repair micro concrete specification for formed pour repairs where partial fill is not an acceptable outcome.
