Making and Lining a 6 foot deep manhole pit:

There are tree roots in the main drain from the house,
the drain engineer suggested inserting a new access point
to clear the roots, and maybe insert a plastic liner.

I guess the hole needs to be about 6 feet deep,
and have a possible loan of a digger and driver.

But how big to make the hole,
and how to line it?
Blocks or concrete how thick?
or newfangled plastic ?

Oh just get bog (sic!) standard plastic sections

6 foot doesnt need a digger for a man hole. Just a day with a delving iron.


Make it about 1 ft bigger than the manhole so there's a 6 " gap all
round and bed in on pea shingle

Is it old clay pipe?

Frankly unless you realy want to play drains a good groundworker or two
will do this in a day or max 2 days for |£3-500 I'd guess.
