These are photos of work, carried out in about 2007, that I had nothing to do with.

But they show how bad unsupervised concreting can be.

It really does seem as if the contractor covered up the leaking concrete with drainage membrane having done nothing to improve the terrible work or reduce the leaks.

The drainage membrane over the floor is still down, as well as any insulation and the floor screed over it.

So this area is leaking, probably worse lower down, over an area over a foot high.

This is a concrete pile that was not covered over, as no doubt it should have been.
