New to the site and looking for a little guidance.
We have just moved in and there is a drainage channel (see photo hopefully) that has been built between the walls of the garage door entrance. The door closes on top of this so that the channel is visible inside. Is this correct and is it also right than the channel doesn’t drain into anything, it’s just a long channel?
I would have thought that it should be outside the garage walls and that it should have a pipe that leads into the drainpipe drainage?
The house builder has told me this is not a defect?
