Scaling may result from freeze-thaw, but also from salts, corrosion or a weak surface layer. Learn what evidence can help.
Concrete investigation before repair: from inspection to report
Which visual, field and laboratory investigations help before repair, and how should you read the limits of a report?
Repair methods
Choosing a concrete repair method: start with the cause and objective
Compare monitoring, local repair, crack treatment, protection and structural repair. Learn which questions should guide the choice.
Concrete patch repair: when is hand-applied mortar suitable?
Learn when a shallow patch with hand-applied cementitious repair mortar is suitable, how the substrate is prepared and when structural design is needed.
Concrete crack injection: when does it help?
Learn when concrete cracks are injected, how repair purpose, movement and moisture affect material choice, and what to discuss with a specialist.
Concrete repair with shotcrete: when does it fit?
Learn when wet or dry mix shotcrete may suit concrete repair and how preparation, placement and inspection affect quality.
Protecting concrete with coatings or hydrophobic impregnation
Compare film-forming coatings and penetrating water repellents, their functions, limits and pre-application checks.
Cathodic protection of reinforcement in concrete
Compare galvanic anodes and impressed current for corrosion control in reinforced concrete, including monitoring and asset management.

Learn where CFRP may fit, what an engineer assesses and how installation is checked.
Concrete repair with formwork: pouring or pumping?
Compare form-and-pour and form-and-pump repair, and learn how preparation, placement and inspection depend on the cavity.
Removing damaged concrete and preparing the substrate
Learn how assessment, removal and cleaning prepare concrete for repair, and which acceptance checks depend on the project.
Repairing and protecting reinforcement in concrete repairs
Learn what local concrete repair involves when reinforcement is exposed or affected, and which decisions depend on assessment and structural design.
Sealing concrete cracks and joints
Compare surface sealing, routing and flexible joint sealants. Select an approach based on movement, water and function.
