SikaWrap-231 C IN
India-grade high-strength unidirectional carbon fabric for dry lay-up strengthening
Product Overview
SikaWrap-231 C IN is an India-grade, unidirectional woven carbon fibre fabric engineered for the Sika dry lay-up strengthening system. Its warp is built from high-strength carbon filaments aligned at 0 degrees, with a heat-set glass fibre weft that keeps the sheet square and easy to position. Applied with Sikadur-330 IN, which acts as both primer and laminating resin, it cures into a stiff carbon laminate that raises axial, flexural and shear capacity, confines columns and corrects design or construction shortfalls. It is widely specified for seismic upgrades of buildings, bridges, silos and water structures. Locally optimised packaging suits Indian site logistics. Space Arc Engineering, an authorized Sika distributor, stocks SikaWrap-231 C IN together with Sikadur-330 IN for strengthening contractors throughout India.
Features & Benefits
- High-strength carbon fibres deliver about 4,900 N/mm2 tensile strength and a 250,000 N/mm2 modulus
- Heat-set glass weft locks fibre alignment for crease-free, accurate placement
- Single-product dry system with Sikadur-330 IN simplifies on-site application
- India-grade format and packaging matched to local project conditions
- Conforms tightly to beams, columns, walls and silos of varied geometry
- Non-corroding, low-weight substitute for added steel reinforcement
Technical Highlights
| Coverage | Sikadur-330 IN consumption is roughly 0.8 to 1.2 kg/m2 for the first layer and 0.5 to 0.8 kg/m2 for each following layer. |
| Strength | Carbon fibre tensile strength of about 4,900 N/mm2 with a tensile modulus near 250,000 N/mm2 and elongation at break around 2.1%. |
| Performance | Forms a thin 0.127 mm structural laminate (about 127 mm2 cross-section per metre width) for high tensile reinforcement, refer to TDS for design values. |
| Application Conditions | Apply to a clean, laitance-free, open-textured substrate of at least 1.0 N/mm2 tensile strength; observe Sikadur-330 IN temperature limits, refer to TDS. |
| Packaging | Supplied as one roll per carton, 500 mm wide and 50 m or more in length. |
Applications
- Seismic retrofitting of columns and beam-column joints in multi-storey buildings
- Flexural and shear upgrading of RC bridge and flyover members on infrastructure works
- Strengthening industrial silos, chimneys and process structures against added loads
- Repairing under-designed or defective elements in commercial construction
- Wrapping residential columns and slabs during structural rehabilitation

Frequently Asked Questions
What is the difference between SikaWrap-231 C IN and SikaWrap-230 C?
SikaWrap-231 C IN is the India-grade version using high-strength carbon fibres rated near 4,900 N/mm2 with a glass-fibre weft, optimised for the dry lay-up method with Sikadur-330 IN and locally suited packaging.
Is SikaWrap-231 C IN applied wet or dry?
It is designed for the dry application process, where Sikadur-330 IN is first applied to the prepared substrate and the fabric is then pressed in and over-coated with the same resin.
Where can SikaWrap-231 C IN be used?
It strengthens reinforced concrete, masonry, brickwork and timber – increasing axial, flexural and shear capacity, confining columns and improving seismic performance for buildings, bridges and industrial structures.
What roll size does SikaWrap-231 C IN come in?
It is supplied as a single roll per carton, 500 mm wide and 50 m or longer, which suits column wrapping and continuous beam strengthening.
