In case these pages carry with them the idea that we are the dream builders previously only guessed at in the history books and these days only occasionally glimpsed in the gloaming or rumoured to be well and speaking German. These two images are amongst our better disasters.
This was a concrete screed we poured in a lower basement flat in Edinburgh.
The screed had to be pumped into the basement because of the access problems associated with working two floors below ground level. The screed was layed over an underfloor heating system.
A hardwood floating floor was to be fitted over the screed and to make things a little more difficult the shadow gapped plastered walls were already in place and the screed had to finsh precisely 85mm below the plaster beads all round the perimeter of the room.
Everything went to plan except that the screed didn't harden - the second image shows a pencil which we pushed into the floor a week or so after the screed was layed. - This was a complete disaster and the screed had to be lifted also destroying the network of pipes within the screed associated with the underfloor heating and the thermal insulation and damp proof membrane below that.
Our concrete supplier (anonymous here) said the fault lay in a computer malfunction at their plant.
