evenin, I'm building a porch about 2m x 2.1m and have dug the trenches for the foundations - we're at a depth of more than 2m as the BCO wanted us to go to same depth as the house foundations. Problem is we've uncovered a main foul water drain which has been encased in a large amount of concrete by the original builders. This would be OK if the drain was crossing through the middle of one the new porch walls, we'd just lintel over it somehow (I'm assuming we can't build directly off this concrete). Problem is the drain crosses the new porch precisely in one of its corners. The only way I can see of supporting the new porch at this corner is to dig away alot more ground and put in a diagonal lintel. If that's what the BCO wants then we'll have to do it, but I'm looking for a better/quicker/cheaper solution. Any ideas folks? TIA,
Nick
