There are a few options when dealing with laterals. Measuring and cutting the line will work very efficiently in a pull-in place system vs an inversion where stretch is very present. However, lining a LMC T or Y Liner can be an option as well as using a Picote cutter that we distribute. Give us a call at 1-888-337-6764 to discuss this, it'll be a pleasure.

TheUntubed Thanks for the comment and questions. The first step towards installing Formadrain is cleaning and inspecting. After we do that, we can tell if we are able to repair the pipes without excavation. Some restrictions in size and configuration apply, but in general the answer is yes, we can repair old pipes under a slab without breaking the floor open. The resulting repair is 100% structural and watertight, no digging required!
