We have a 1930s suspended floor construction. Pretty much like the construction seen in the attached image.
I laid my new mdpe water pipe in a trench in the front garden, and passed some ducting (110mm soil pipe) under the porch, an v it had to go under the footings of the outside wall. I made a hole just about big enough to pass the soil pipe through.
Do I need a lintel over this pipe, or should it be ok given that it's only 140mm hole. Access would be a knightmare to dig this out properly. From the outside I have to squeeze between the garden path and garden wall where all of drainage, gas, electric and water pipes run, plus having to go underneath the porch which is 1m depth.
From the inside it isn't much better. Would have to pull up all the floor boards and work between joists, digging out 100mm of concrete.
Perhaps I can try and put some concrete between the tiny gap between the top of the pipe and the footings?
