Recently, the construction industry has started using fibre composites in the repair and rehabilitation projects of commercial, industrial, residential, and transportation structures. Locally, the currently most commonly used fibre composites are single- and multi-ply composites made of uni- or bi-directional carbon or glass fibre mats and epoxy resins. Where properly used, they can add significant strength to structural elements at a very small weight penalty.
Applications range from small-scale strengthening of masonry walls in heritage buildings, to seismic upgrades of commercial and industrial structures, to strengthening of highway bridges. Metro provides quality assurance, quality control, and testing services related to fibre composite installations. These services include: materials consulting, specifications, installation monitoring, in-situ bond testing, witness panel testing (determining of tensile strength, modulus, and elongation-to-rupture to ASTM D3039) and trouble shooting.
