Problem with newly laid concrete floor

[Lujay]

hi all,

I'm new to this site and I was after some opinions on the floor in a newly built ground floor extension.

The builders who built the extension screeded the floor but have left some brick exposed all along where the bifold doors are fitted. Hopefully you can see it in the photo in my album. It runs about three metres across by the bi-folds.

Another builder we know (didn't use as he was too expensive!) said these exposed bricks will cause damp problems and will ruin the oak wood floor we plan to install. He said we should ask the builders to remove the top layer of brick and apply a membrane before re-screeding the area.

We put this to the builder we have used and he said he thinks it's enough just to out a membrane down underneath the floor underlay.

Any opinions on who to believe?

Many thanks,

Lujay

Is there a DP membrane beneath the bricks?
If not I would not be too pleased!

Hilarious.

As said these bricks should have been chopped off, a membrane put down in the trough and screeded right up to the door sill.

There will be no DPC beneath these bricks because what you are looking at is actually DPC level.

Thank you for your help guys. Spoke to builder and he has promised to apply a plastic membrane over the bricks, a metre into the room. He said they're engineering bricks so "nothing should get through them anyway." We can only hope...

and yet you still put a dpm ontop of engineering bricks when a wall is built,
