|   New drains.  They're fine.
 |   Loads of old tat buried in the garden.  Ebay, anyone?
 |   This is the problem: the building inspector isn't happy with the material the ground is made of, these trenches are now over 6 feet deep and we've hit water and need to hire a pump to keep digging.  If the inspector still isn't happy next visit, it might need piling, despite the fact that a detached house has stood on this ground for over 80 years.  Start counting the extra cost...
