Grovedale drain relining

A local plumber we do some work for called the other day, he had removed a toilet to repace it as part of a renovation. When he looked down the sewer  pipe about 1 meter under the slab the sewer drain had come apart and there was a significant entry of roots.  Options where take up tiles , jack hammer up slab to replace section of pipe , or reline damaged section of drain. We cut roots out with the water jet and installed section of relining 4 hours later no mess no fuss, slab and tiles intact. Job Done.
