Hi!
I'm looking to build my front extension - unfortunately due to a pesky public drain my footings need to be 1.7m deep (150mm below invert within 3m)!. I have received a quote from a ground worker for £6k to do the work including concrete fill and muck away. The footings are approx. 0.6mm wide x 1.7m deep x 10m long.
I hand dug the footings at the rear (0.6m wide x1.2m deep x15m long) mainly due to poor access so I'm considering doing it again out the front.
Has anyone hand dug such deep footings?
Am I mad?
How can I do it safely - is it even worth it? OSB boards with supports between? I'm guessing it will be hard work throwing clay out of a deep trench...
Does the groundworkers price seem OK - I'm happy to delay works until next year to see if prices drop a little (although they may not!?)
Thanks...
