Hi all,
When I installed this sliding door, I foolishly put it straight on the slab thinking exterior sealant would be sufficient to keep water out.
Unfortunately it’s not…
Every time it rains heavily I get water creeping underneath it or collecting in the track and then seeping through.
Is there any waterproofing fix you guys can think off, that doesn’t involve taking the door (frame) out, shaving some of the header above it off, adding a sub sill and proper flashing tape underneath the track?
Also, would some concrete crack filler be sufficient to prevent water creeping through the crack in the slab?
Many thanks in advance!
Thank you for all your very useful suggestions!
Do you think cutting a draining channel into the slab just outside the door (instead of sloping the entire slab) could also work?
