ᐅ Roller bearings in the sliding doors

Hello,

we were asked if we wanted to have rolling layers (roller screeds) at the patio doors. As far as I know, it’s definitely not a bad idea in terms of water protection. However, I’m not particularly keen on them because we specifically chose a low-profile construction for the patio door. We wanted to avoid a high step, but the rolling layer would create one again. You can find mixed opinions about this online, as is probably the case everywhere.

Has anyone here decided against the rolling layer and could share how they sealed the area later on? Are your patio slabs or paving installed directly up to the door, or is there a drainage channel in between?

So far, several coats of MB 2k from Remmers have been applied.

I would appreciate any tips.

The alternative is a grate in front of the door. I would choose one of the two.

Wooden deck up to the door (without a gravel layer). This way, you also avoid having an unsightly grate in front of it.

My husband insisted on having a channel. However, our research showed that hardly anyone does this, so we decided against it. Due to the slope and the roof overhang, even heavy rainwater doesn’t really reach that area, so a channel wasn’t necessary!

If we had solidly grouted tiles, I probably would have opted for it, but in our case it didn’t make any sense. We realized this only afterward.

Oh, unless the door is completely flush with the floor, then we probably would have installed a trench drain!

That is the OP’s plan.
