Column Jacketing vs. FRP Carbon Wrapping: Which is Right for You?
Restoring Load-Bearing Capacity
When an audit report flags a column as 'Weak,' you have two choices. Traditional RCC Jacketing involves adding a 75mm-100mm layer of new concrete and steel around the column. While strong, it reduces your carpet area.
Why FRP Wrapping is Trending in 2026:
FRP (Fiber Reinforced Polymer), often called Carbon Wrapping, is only 3mm thick but has a tensile strength higher than steel. It is wrapped around the column like a high-strength bandage.
- No Space Loss: Perfect for internal bedroom columns.
- Corrosion Proof: Carbon fiber does not rust, unlike steel jacketing.
- Speed: A column can be strengthened in 24 hours compared to 7 days for RCC jacketing.
