Block and beam floors covered in mortar slurry

Hi

I would like to know the reasons why a block and beam floor is covered in a slurry mix?

Many thanks

Maybe it wasn't level? Or wasn't the right level? Is it a real or theoretical floor, if real, whose floor is it, who laid it, and why don't they know?

It's standard practice to grout the floor, as it fills any small gaps between the units.

It's my floor, and it wasn't slurry'd before the DPM went down. So I was trying to establish the reason for slurry and any consequences from it not being done.

Is there any consequences if its not done?

I've never seen it not done(as it's a simple job), so I can't really say what problems there could be. As the units are not bonded together there could be some slight movement.

AFAIK it's just to stop the floor deflecting a lot when you put the screed down. Once the screed's down though, it'll be as solid as a rock, with or without grouting.

I also think it might be to try and prevent damage when block laying inside.

Post back in a years time and let us know.

If you look at your bnb spec it will say it needs grouting, bc also normally look for it. It locks all the blocks together and makes the floor into one big slab.
