Levelling garage floor with very little drop...

Hi folks.

Planning to turn my concrete garage floor (pictures A, B, C & D) into a flatter surface, so it can be more of a functional space. This isn't a conversion.

Garage is three internal walls, and cr*ppy wooden external double doors.

Moisture levels are below 14% throughout, and generally around 2%.

I don't believe there's a DPC/M, but - despite this - it's generally very dry in there and no sign of damp whatsoever.

The problem: there's only a 2cm drop between the garage floor and the internal floor (picture E), for me to work with.

What's the best way to level it, so I can lay 10mm engineered wood flooring? Here's what I plan, so far...

I plan to floor-grind and then clean the whole area.

Screed with either self-leveling latex or self-levelling acrylic.

Then lay the underlay and 10mm thin flooring.

Also, at the front of the garage, where the doors are, I assume I just build some wooden battens against the ground to stop the SLC from flowing against the doors?

Thanks in advance for any tips!!

 

Don't know.
But is there some kind of epoxy paint/floor leveller that will be a combined DPM?

When we did a garage conversion at a mate's we roughly levelled a floor to remove links, then used a bitumen paint. we laid a strong poly DPM over that and built the floor floating on rock wool. You have almost no room for insulation. The floor could be really cold.

 

Thanks for your reply

It will be cold, and if I was doing a full conversion I'd obviously pull the existing floor up and check for/lay a DPM and full insulation.

But it's rather to make it look better and be a bit more functional.

I think I can get away with it, but just wanted to check.

 

So will you have 2cm between the existing floor and the underneath of the lording? Or is that top to top?

 

I've currently got only 2cm between the level of the internal house floor and the level of the garage concrete (you step from one to the other via a doorway).

I figure a 5-10mm SLC and then 10mm thin wood panels applied to the garage concrete should equal (and hopefully not exceed) the 20mm I've got to play with.

 

Not a builder.
A liquid epoxy dpm then latex screed. Sounds thin

 

Could u tile it? Even use wood effect tiles.

 

Yeah I could tile it happily. I assume it's best to still level it with an SLC before though?

 

Cheers. Hadn't considered liquid DPM beneath the latex screed

 

Yeah, but depends how far out of level it is. If its only a few mil here n there, u should be able to sort it with adhesive. U should also put a piece of rubber mat down for a few days. Then check under it after say a week. If there is patch, then you've got moisture in your floor and no type of flooring will last long.

 

Cheers, I'll get on that today
