The Importance of Micro-Concreting in Structural Strengthening
Precision Strength for Old Structures
When a building column loses its load-bearing capacity, Micro-Concreting is the 2026 solution for 'Jacketing.' It is a flowable, non-shrink, high-strength cementitious material designed for tight spaces.
Why Use Micro-Concrete?
- Self-Compacting: It flows into dense reinforcement cages without the need for mechanical vibration, ensuring zero air pockets.
- High Early Strength: Reaches structural grade strength (M40-M60) much faster than traditional concrete, reducing project timelines.
- Excellent Bond: Formulated with polymers that ensure a monolithic bond between the old concrete surface and the new jacket.
Frequently Asked Questions (FAQ)
No. Grouting fills small cracks, while micro-concreting is used to rebuild entire structural sections like columns and beams.
Yes, typically a 'jacket' adds 50mm to 100mm to the column width, but it significantly increases the building's lifespan.
