I have been digging trenches for foundations. They are getting flooded as there is water coming in from a small localised area. This area is beneath next doors extension so I am guessing there is burst pipe somewhere beneath their extension. The problem is the house is let and the owner basically doesnt give a toss as long as it doesnt effect his house which it doesnt seem to be. I can pump it out but what is the building inspector going to say, will he allow me to continue or is there sometihng additional I will have to add to the foundations where the water comes in ?
