Why do bridges need strengthening?
If the existing steel reinforcement is reduced in capacity due to corrosion, if the traffic loads are increased (i.e. permissible axle weights), or if the structural design or seismic resistance needs improvement, then reinforced concrete bridges have to be strengthened, or strengthening systems to be applied.
- High tensile resistance to reinforce and upgrade structurally deficient beams, slabs etc
- Easy to install
- Fast application
