Trenchless technologies make it possible to repair or even replace an entire pipe without digging it up. NASSCO member companies have been at the forefront of this innovation through the development and application of pipe bursting, cured-in-place pipe, grouting, slip lining, spiral sound pipe, concrete and cementitious sprays, and more. Many of these technologies may also be applied to lateral and manhole rehabilitation, providing for holistic rehabilitation of an entire underground system.
