Deja vu.

I have blipped an image very similar to this before when Stu first checked the drains were ok. Tonight he has had to start digging again as we need to move some pipes and put in new drains. The ground was a bit tougher this time as there were bits of rubble and concrete from when the extension was done. Stu dug a bit too well though uncovering an open sewer we didn't realise was there, so a bit more investigation needs to be done.
I have mopped the bathroom and bedroom floor to get rid of some of the dust and started scraping up more dried plaster from the floor. I'm not sure we will ever get things clean again!
