selection of appropriate repair technique

Having assessed the likely progress and course of corrosion using the Carbonation and/or Chloride tools.  This needs to be put into context with the total service life required for the structure. 

Please note that corrosion may be triggered by a combination of factors which may include carbonation and chlorides.


If the assessment indicates that the degree of corrosion of the steel reinforcement will allow the set 'maximum level of permissible corrosion' to be reached before the end of the desired service life, an intervention and/or repair and protection strategy will need to be established.

Through a single or more likely a series of planned interventions, the corrosion can be controlled such that the time at which damaging corrosion (maximum permissible) of the steel is reached after the total life of the structure has been achieved.

Activate the Recommendation tool by clicking the highlighted link.

The main inputs expected within the recommendation tool are the 'Year of Corrosion Initiationdeduced from the Time to Corrosion Initiation analysis,  the 'Year of End of Service Life' from the project details and checking of either Carbonation or Chloride depending on which analysis the year of corrosion initiation is associated with.

The first three inputs 'Structure Name, Year of Construction & Year of Survey' are essential if you require a record of the recommendation for a report or future reference.

Based on the inputs submitted to the tool, a report is presented to the user detailing the most appropriate repair techniques.

The recommendation may be as simple as providing a new coating every 5 years or may involve a combination of different repair techniques e.g. patch repair, coatings and cathodic protection.

The text produced within the Recommendation text area can be copied and pasted within a report or a document for future reference.
