EX Method is a PVC trenchless structural lining system manufactured in Australia under factory-controlled quality standards. It is a ‘Fold and Form’ renewal method.

The material of choice for new sewer pipes is PVC: an EX liner provides the same strength, durability and long life of a new PVC pipe without the need for costly excavation. Entry to access chambers is generally not required by personnel during the process of installation.

The benefits of the EX Method lining system include:


  • Installation of multiple liners each day;
  • The finished liner is joint free along its length with smooth transitions at offsets and bends;
  • Proven track record of success, having been installed in Australia since 1993;
  • Improvements in flow capacity of up to 40%;
  • Australian-made.
