Which leveling compound

[Derbyboy]

I have a gutter in front of a sliding door where I lack flooring. The sliding door is on the foundation wall, but the door is not as deep as the foundation wall. The question is what should I fill in the gutter between the sliding door and the flooring. The gutter is maybe 4 cm deep, 6 meters long, and the height to be filled should be about 20-22mm.

Expanding foam? I've solved my similar problems with that, you're not going to walk there anyway.

 

[Derbyboy]

Yes, foam might be an option, though it is more difficult to work with than some form of cement-based product.

Thinking it would be easy to first tape so that the groove is sealed (today there are some gaps where the floor joists are embedded in the foundation wall) and then pour on self-leveling compound.

It probably works well

 

[Derbyboy]

It seems a bit unnecessary to reinforce, but on, for example, Byggmax self-leveling compound, it says that it must be reinforced.

 

[Andreas_kalmar]

Is there fiber-reinforced filler

 

[Derbyboy]

Yes, that's what I read on the Byggmax site. Their fiberdörstärka required reinforcement.

The best would have been some pu foam but hard to find as a private person but as mentioned expanding foam reads most things.

But it's probably only when you need to reinforce the flooring, before tiling.

But strips of floor chipboard then if it needs to go up 22mm?

But that's probably only when you're reinforcing a floor structure, before tiling.

But strips of floor chipboard then if it needs to be raised 22mm?

Unfortunately, I have nothing to attach to. Just a foundation wall (concrete hollow blocks) as the base. Although I do have floor joists at 60 cm centers where I could drive a screw in, but that probably won't work well.

The question is which self-leveling compound should I use?

Fiber-reinforced of course, but then what.....

 

[Andreas_kalmar]

Cm 700 at Bauhaus if it is nearby

 

[Derbyboy]

It's nearby

 

[Andreas_kalmar]

Fiber-reinforced, however, floats worse so you know

 

[Derbyboy]

Thanks, I'm thinking of pouring it out with a type of measuring jug with a spout. I walk along the gutter and pour.

It's only 4x2x600 cm, i.e., 4800 cm3, which is only about 5 liters.
