ᐅ Constructing a Garage Threshold With or Without Steel Angle Brackets

Hello everyone,

I still have some finishing work left to do on our new build. Unfortunately, there are a few tasks remaining that aren’t straightforward.

We have a screed floor with tiles in the internal garage. Now there is a gap between the asphalt driveway and the garage floor (see pictures). You can still see the concrete slab and the exposed edge of the screed. For insulation, I plan to first lay a thin XPS board over the entire area, followed by screed. Then I want to seal the screed with a tile waterproofing membrane, creating a transition to the existing screed. I was thinking of installing a small threshold as well. For this, I would attach a stainless steel angle profile onto the screed. However, I’m not sure if this is common practice or how exactly it should be fixed (screwed and glued with tile adhesive?). On top of the screed, I would then bond granite slabs. Another option might be to have the slope of the slabs steeper and skip the angle profile altogether.

Is this approach feasible, and how should the angle profile be secured?

Good luck, Martin
