Hello,
we have the problem that the joints on our terrace were washed out during cleaning with a Kärcher and surface nozzle. We would like to re-grout the joints and this time use something that lasts permanently.
It does not have to be water-permeable because we have a drainage channel at the end of the terrace. We have concrete terrace slabs, part of which are laid in gravel and the extension in a sand/cement mixture.
What can we use to grout the joints of the terrace permanently so that it hardens in the end and stays in place?
