Traction reinforcements in elements subject to bending such as beams, joists, slabs.
Removing supporting elements (walls, columns...).
Opening of gaps in slabs for installations, stairs, etc.
Changes in use:
Due to increases in service loads.
Installing heavy machinery in buildings.
Increase in traffic on bridges.
Appearance of vibrations in the structure, earthquake reinforcements.
Structural deterioration or damage in service:
Ageing of the materials making up the structure.
Reduction of the rebar sections due to corrosion.
Reduction of arrows and deformations.
Controlling, reducing and stitching structural cracks and fissures.
It improves the structure’s behaviour against fatigue.
Execution or project errors:
Insufficient rebar or poorly fixed.
Drop in the envisaged concrete strength.
Cutting resistant elements and rebars with a drill.
