OMPT GROUPE recently created a stairwell opening in a reinforced concrete floor, followed by structural reinforcement with carbon fibre plates.

Details of the work:

  1. Creating the opening:
    A precise 170×160 cm cut was made in a 21 cm thick solid slab floor with a diamond circular saw. The rubble was removed immediately to keep the site clean.
  2. Reinforcement with carbon fibre plates:
    To make up for the loss of strength, carbon fibre plates were installed over 6.30 linear metres, bonded to the floor with S&P Resin 220HP adhesive, as specified by the structural engineering office (BET).
  3. Finishing:
    The site was cleaned after the work to ensure a clean, safe environment.

This work effectively strengthened the structure while creating the opening needed for the staircase, safeguarding the building's longevity.
