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.

  basement sump pumping 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 water was coming in so fast that the pump was switching on every 50 seconds. During 8 years and over 5 million pump cycles many pumps broke down and every breakdown flooded the basement in under 10 minutes.

This is a short video of the sump and the pumps that fail from time to time because of the massive workload.

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