Makeup Height For new LVP Flooring

Dabz86 · 28 Oct 2025

I'm looking to replace some existing laminate floor with LVP. The existing makeup height is 15mm (7mm laminate + 8mm underlay). The thickest LVP tile I can get is around 6mm with integrated underlay.

The subfloor is concrete on a top floor flat so I won't need a DPM - however at only 6mm there would be a huge 9mm gap under my skirtings, fixed furniture etc.

Most LVP manufacturers advise that the tiles should go directly onto the subfloor - what are my options to add some makeup height to the concrete? Levelling compound is not an option.

Thanks

Save yourself a load of heartbreak and replace with Laminate again. Click LVP is notorious for failing even when subfloors are fully screeded and level, the joints are so thin they are susceptible to breaking easily.

This is the first time I've heard of this. Mostly all the reviews and comparisons I see between the 2 favor LVP. After all, they both use click lock system and the only difference between them being LVP is waterproof due to the core material being PVC. Do you have any examples or links to where LVP has failed?

We have replaced many, many LVP floors the past few years including a 5 plot luxury home development.

You only have to do a search on any floor fitting forum to see the issues attributed to LVP. Not only do subfloors HAVE to be prepared the same as Glue Down LVT, you also have to be very careful about how much weight has been put on top.

We had one LVP manufacturer refuse a warranty claim on a Kitchen that we fitted not because of any issue with the floor prep or fitting, but because a washing machine was in use on the floor!

That's interesting, thanks for the insight. If I was to go down the laminate route, would I be okay to use a cork or rubber acoustic 3-5mm underlay and with 10mm laminate?

Yes that should be fine.

The best laminate floor underlay is Timbermate XL

That's good but I am also considering this as it provides up to 54dB reduction https://sounddeadeninguk.co.uk/prod...ountry=GB&currency=GBP&variant=55617018659202 - I'm assuming this will also be fine?

That will work too.
