Under-slab drain replacement means taking out the buried cast iron and laying new PVC drain pipe at the correct slope. The crew reaches the pipe by cutting a trench through the floor or by tunneling under the slab from outside the house. Replacement fixes any pipe condition, including collapsed and bellied sections that lining cannot fix.
A full replacement typically takes 11 to 26 days, longer than lining, because the floor or tunnel must be opened, inspected and restored. Many Bradenton jobs replace only the worst run, such as the main drain under the kitchen, and line the sound branches.
Bradenton slabs from the 1950s to the 1970s sit on sandy fill, often close to the water table. Where the drain runs under tile or terrazzo, tunneling from outside can save the floor; where it runs under carpet or a garage, a trench is often faster.
