SikaWrap®-230 C

Woven unidirectional carbon fibre fabric, designed for structural strengthening applications as part of the Sika® strengthening system

SikaWrap®-230 C is a unidirectional woven carbon fibre fabric with mid-range strength, designed for installation using the dry or wet application process. Suitable for use in hot and tropical climatic conditions.

  • Manufacturedwith heat-set weft fibres to keep the fabric stable
  • Multifunctional fabric for use in many different strengthening applications
  • Flexible and accommodating of different surface planes and geometry (beams, columns, chimneys, piles, walls, soffits, silos etc.)
  • Available in different widths for optimum utilisation
  • Low density for minimal additional weight
  • Extremely cost effective in comparison to traditional strengthening techniques

Usage

Structural strengthening of reinforced concrete, masonry, brickwork and timber elements or structures, to increase flexural and shear loading capacity for:
  • Improved seismic performance of masonry walls
  • Replacing missing steel reinforcement
  • Increasing the strength and ductility of columns
  • Increasing the loading capacity of structural elements
  • Enabling changes in use / alterations and refurbishment
  • Correcting structural design and / or construction defects
  • Increasing resistance to seismic movement
  • Improving service life and durability
  • Structural upgrading to comply with current standards
