SikaWrap®-930 G

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

SikaWrap®-930 G is a unidirectional woven glass fibre fabric designed for installation using the wet application process.

  • Manufactured with 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.)
  • Low density for minimal additional weight
  • Extremely cost effective in comparison to traditional strengthening techniques
  • Very low electrical conductivity

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
  • Increasing the strength and ductility of columns
  • 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
  • Blast mitigation (accidents or terrorism)
  • Electrical environments that ask for non-conductive material
