How do i fill the gap under my outdoor sliding door and alresco slab?

I’m currently tiling my alfresco slab and wondering how do I fill the gap/void between my outdoor sliding door track and the slab/tile? Is it best to tile under the track or add something underneath it to hold up the track?

Good afternoon @aydenmb21 

 

It was a long time ago and my gap is bigger - but I used a piece of decking and concrete bolts.

For that 'perfect' fit - I had to hand plane it in sections, but it made a really positive effect to the sliding door movement.

Just a post hamburger for lunch thought.

Cheers!

Hi @aydenmb21,

 

Does the track need to be held up, and have you removed any structural support from under it? If not, then the gap is really only cosmetic, and @Noyade has provided a great option. 

 

You could tile under there if you wished, if that's a look you'd like.

 

The gap looks a little too large to fill with Sikaflex 11FC, but you could do so. Regardless, I'd be inclined to run a bead of this across the vertical concrete to seal it off and prevent water ingress under the door. Then, you could use a timber or aluminium profile to cap off the area.

 

Please let us know if you have any questions.
