Waterproof sliding door glued to shed slab?
(aussie.zone)
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!
When I used to install these we would put down a thick silicone or construction adhesive base then set the door on top of it.
What does the concrete slab look like? It's not running back towards the house is it?
Yeah, I put lots of silicone underneath the track / frame too. The slab was meant to slope away but that got lost in translation with the concreter and as a result has been poured dead flat / level, which doesn’t help of course…
I was thinking I could cut a grout like drain channel 2-3cm away from the door to lead some of that water away from the door.
