Ive got a dilemma I have a sewer main built underneath
my driveway all the way up my property however it is 7" feet to 8" feet
below the ground and im well aware of the proceedure that I have to concrete
encase the pipe but I have an access manhole behind where I want to build,
do I need to encase? as there is only a slab for a garage going over it so it isnt
going to affect the sewer main.
