Product Overview

Renderoc CF is a controlled-flow repair mortar from Fosroc designed for formed (shuttered) repairs to structural concrete elements where hand-applied mortars like Renderoc HB2 cannot be used due to the geometry, depth, or inaccessibility of the repair area. In formed repairs, the mortar is mixed to a flowing consistency and poured or pumped into formwork erected around the repair area, where it flows to fill the shuttered void without requiring extensive manual compaction. This approach is used for repair of concrete columns, piers, piles, beams, and soffits where the deterioration is deep, covers a large area, or where access for hand application is restricted. Renderoc CF is fibre-reinforced to control plastic shrinkage cracking, which is particularly important in formed repairs that are encased in formwork and cannot be finished or retrowelled as they set. The product is pre-bagged as a single-component mortar requiring only the addition of clean water — ensuring consistent quality and eliminating the need for site mixing of multiple components. Renderoc CF achieves high compressive and tensile bond strength, is compatible with the reinforcing steel environment, and can be finished to a surface that matches the parent concrete in colour and texture. Space Arc Engineering distributes Renderoc CF for bridge, infrastructure, and building repair and rehabilitation projects across Delhi NCR, Ghaziabad, and Northern India.

Applications

• Formed repairs to deteriorated bridge columns and piers
• Shuttered repairs to building columns and wall panels
• Poured repairs to deteriorated piles and exposed foundations
• Soffit repairs using stay-in-place or conventional formwork
• Deep section repairs where hand-application mortar is not practical
• Encapsulation repairs to corroding reinforcement in large concrete members

Key Advantages

• Controlled flow consistency — pourable into formwork without excessive compaction
• Fibre reinforcement for plastic shrinkage crack resistance
• Single-component — just add water for consistent site mixing
• High bond strength to existing concrete and reinforcing steel
• Chloride-free and low permeability for durable repairs
• Compatible with all Fosroc Renderoc primers and coatings
