We lined a sewer from an overhead stack clean out in the basement 70’ out stoping just before the second overhead tie in from the house sealing off the sewer where heavy tree roots would grow in through the joints and sealing a break in the 4” cast near the foundation wall where sewer water would seep back in/ towards house
Lined the sewer from an open hole near the city side walk out to the city main in the middle of the street which is about 20’ deep! Leaving the pipe like new pvc within the old clay tile pipe, with out needing to trench through the side walk or road saving a lot of restoration cost for the home owner.
Televised sewer for installation of liner.
Look at under slab ducts, getting water into basement where duct go through wall. Recommend lowing water table under slab.
