Screed pouring

[saveasteading]

For anyone who hasn't seen it, pumped screed is incredibly fluid and that's why we have to seal all possible escape routes.

The reality is that, although it looks almost like water, this material is mostly cementitious and gritty. Nearly all the water is absorbed in chemical reaction and it is solid-ish within an hour.

But any gap can be disastrous. 

This went well.

A few dribbles of water emerged through plasterboard below but that's OK.

They often set the levels with several small tripods and work to them.  That way they don't need the laser level and staff/receiver while they are pouring.

I prefer to see that.

These people used neither laser nor tripods ( I like to call them triffids) for the ground floor and just a stick to measure minimum thickness. Hence it simply followed the lumps and shapes above the pir layer. We wrongly assumed they understood levels.

 

On the first floor, as shown, they had to use the laser as they had messed up the underlayer: we have a 5mm acoustic mat and they chose to lap the edges in some places. The downside of letting people work unsupervised at the weekend.

So we pointed this out but that raising it all to the highest point would compromise our door frame heights. Hence it's not all one level, but to several zones.

They aren't used to being checked on and managed I feel.
