Floor dip

[phatboy]

Hi all,

In our dining room, the floor is partly concrete (an old outside step), and the rest suspended timber. Where these 2 meet, 1 part has developed a dip. It would have been caused by me simply popping some mortar where a gap was showing after replacing the original floorboards, and that slipping (Silly me!).

The issue is, the floor is lino, that is glued down all over. And there is a storage heater in that corner.

I need a solution to fill the small void that can be felt under foot, without lifting the lino. I am thinking some sort of resin, injected into the gap with a huge needle? Or cutting a small slit on a line and pushing resin in.

Any thoughts? I've been meaning to deal with this for ages, but as most other lockdown jobs are done, this one now needs seeing to.

Thanks

Can you crawl under the floor?

Can you crawl under the floor?

Not since the lino went down... I put 2 nice hatches for access to either side, but the lino sealed them down!

any genius ideas?

Nothing genius I'm afraid. Is this soft spot where you've got timber boards above a concrete screed? Or is it lino straight onto the concrete? Whichever, if the gap is fairly small you could try injecting Gripfill. Problem with injecting anything is you have no way of cleaning the surfaces which means whatever you chuck down there may not bite properly....did the lino lot not put seams in for your traps? Thought glued lino went down with the Ark Royal anyway, or are we talking vinyl rather than lino (in which case carefully pull it up, do your mend and glue it back down)
