Often, yes. If the pipe under the slab is still round and continuous, a liner goes in through a cleanout and cures into a new pipe. No jackhammering. If the section under the slab has collapsed or sagged badly, it needs tunneling or cutting the floor instead.
Traditional under-slab repair means breaking up the floor inside the house, or tunneling under the foundation from outside, to reach the pipe. Lining skips both. Our crew clears the line, measures it with a camera, pulls in a resin-saturated liner, and cures it in place. The finished liner seals cracks and joints along the full lined length, and the floor above stays untouched.
Most DFW homes sit on concrete slab foundations, and the sewer line often runs under the slab before it leaves the house. Expansive Metroplex clay heaves and settles with the seasons, which cracks cast iron and pulls joints apart right under the floor. Trenchless pipe lining starts at $3,500+. Final cost depends on length, access, and inspection findings.
Lining has a hard limit under a slab. The same soil movement that cracks the pipe can create a belly, a low spot where waste settles. A liner follows the old pipe’s shape, so it seals the belly but does not level it. A camera inspection shows whether the line is round, aligned, and properly sloped before anyone quotes lining.
