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.
You could spray water on it with a gardenhose to see where it's leaking. If it's really coming from under the frame there's this stuff called tixophalte caulk, this is meant to be watertight.
Thanks man! I’ll google and give that a try.
Without a real sill and a slope on the outside your going to have water intrusion. Add a gutter/diverter above the door on the roof. Remove all the sealer you can. Use waterproof concrete sealer/paint on the slab. Fill every gap you can with silicone. Shave down the slab with an angle grinder to add some kind of slope.
If the concrete applier 'forgot' to add a slope to the outside see if they will help with the remedy.
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?
Maybe? When it rains you need to move lots of water fast. It'd need to be a serious channel
Do you have eave troughs there by chance?
No, the gutters and downpipe are on the other side. There is a bit of flashing above the door though.
Do you think water could be leaking from there?
Adding more coverage from above and preventing “puddles” or streams will help whatever solution you end up with on the bottom
