Micro-Concreting Technology: The Secret to Precision Structural Repairs in Mumbai
Why Standard Concrete Fails in Repairs
In structural repair, 'shrinkage' is the enemy. When you patch a column with standard cement-sand mortar, it shrinks as it dries, leaving a microscopic gap between the old and new sections. In 2026, Micro-Concreting has become the mandatory standard for high-performance repairs at Urban Civil Services.
Key Technical Characteristics:
- Non-Shrink: Contains expansion agents that compensate for plastic shrinkage, ensuring a 100% tight bond.
- High Flowability: Can be poured into narrow shuttering gaps (as thin as 25mm) without requiring mechanical vibration.
- Rapid Strength: Reaches M40 or M60 grade strength within days, allowing for faster project completion.
The Application Process:
For a successful 'Jacketing' or 'Slab Repair,' we follow a strict 2026 protocol:
- Surface Prep: Chipping to sound concrete and treating rusted rebars.
- Watertight Shuttering: Since micro-concrete is highly fluid, shuttering must be leak-proof.
- The Pour: Poured continuously from one side to avoid air pockets.
Frequently Asked Questions (FAQ)
Standard repair grades typically achieve 25-30 MPa in 3 days and over 50-60 MPa in 28 days.
No, it requires precise water-to-powder ratios (usually 0.12 to 0.15) to maintain its non-shrink properties.
Yes, its high density makes it much more resistant to water ingress than traditional concrete.
