Repair strategy

Based on the results of the inspection and material research, we develop technical proposals tailored to the client's needs. This advice includes targeted measures for repair and renovation, aiming to extend the structure's lifespan and prevent further damage. This applies both to durability (halting damage mechanisms) and stability (strengthening the structure).

Advice for repair

Based on the investigation, certain hypotheses regarding underlying damage phenomena are examined in more detail, with the aim of identifying the root cause. The repair advice is specifically designed to directly address the cause of the damage. For concrete repairs, recommendations are made in accordance with the principles of NBN EN 1504-9, and the following repair methods may be considered:

  • Application of coatings to protect against the penetration of harmful substances and/or moisture
  • Conventional concrete repair, where contaminated concrete is removed and replaced with suitable repair mortars
  • Cathodic protection, using either sacrificial anodes or impressed current cathodic protection (ICCP)
  • Bonded reinforcement using carbon fiber strips or steel plates

Repair Strategy

Depending on the complexity and budgetary constraints of a project, we develop various scenarios for the repair or protection of the structure. In doing so, we assess the economic impact, including the initial investment cost, the total cost of ownership for the intended maintenance-free service life of the structure, as well as the advantages and risks associated with each repair option.

Technical Execution File

Once a specific scenario has been selected, Sanacon prepares a comprehensive technical execution file, including a work description, execution plans, and cost estimation. This dossier can then be used to launch a tender for qualified contractors.

Supervision Until Completion

After awarding the contract to a contractor, Sanacon can also be involved in monitoring the execution of the works. During site inspections, we specifically verify whether the work is carried out according to best practices and whether all techniques and materials meet the required quality standards.
