Structural Strengthening

REASONS FOR EXTENDING THE FUNCTIONAL SERVICE LIFE OF A STRUCTURE

The use of a building or civil engineering structure may change throughout the course of its service life:

  • Its whole function can change
  • Loads can increase
  • Higher building standards are required
  • Layout may change

 

COMPATIBLE PRODUCTS AND INTEGRATED SYSTEMS TO SUIT EVERY PROJECT

Whether increasing the bending, shear or impact resistance, tested and proven Sika systems are available for use on:

  • Reinforced concrete
  • Steel
  • Wood
  • Masonry load-bearing structures

 

TYPICAL APPLICATION

  • Flexural strengthening for negative and positive moments
  • Column strengthening
  • Beam and slab strengthening
  • Pre-stressed strengthening
  • Seismic upgrading/earthquake damage repair
  • Increasing impact resistance
  • Crack prevention/reduction

Strengthening Systems

Prefabricated CFRP Plates

For strengthening of concrete substrates, prefabricated Carbon Fibre Reinforced Polymer (CFRP) plates can be externally bonded or near surface mounted. Sika offers a wide range of CFRP plates in different dimensions and E-moduli.

FRP L-shape Plates

Shear capacity of concrete beams can be increased by externally applied CFRP strengthening systems. Sika provides unique L-shape CFRP plates for effective anchorage of stirrup forces in concrete compressive zone.

FRP Fabrics

Externally applied fabrics can be used to increase flexural, shear, axial or seismic resistance of structures. Sika offers various fabrics systems, based on different type of materials for specific needs and cost optimized strengthening.

CFRP Post-tensioning Systems

Post-tensioned systems are effective for control of structural cracks and deflections and to increase fatigue resistance and seismic resistance. Sika provides an unique system based on post-tensioned CFRP plates.
