Remarking and revalidation

Protecting on site markings is crucial.


If initial markings done by underground infrastructure owners are no longer visible, you must notify them at once.


If your work continues, you will have to revalidate the locate request before the end date of work written on the latter.

Validity of a request

Your request is valid until the end date of the work written on your request. By revalidating the request, you extend its validity until the new end date of work written on the request.

If your request was initially completed 6 months ago, you must place a new locate request.
