Trenchless technology is a type of subsurface construction work that requires few trenches or no continuous trenches. It is a rapidly growing sector of the construction and civil engineering industry. It can be defined as “a family of methods, materials, and equipment capable of being used for the installation of new or replacement or rehabilitation of existing underground infrastructure with minimal disruption to surface traffic, business, and other activities.”
Using specialized equipment underground infrastructure is installed, repaired or replaced with minimal ecological disturbance. Infrastructure can be installed under buildings, under forests, under wetlands and bodies of water.
No one likes their home, business or morning commute to be affected by construction. The footprint for a trenchless construction zone is smaller and often times done in an existing right of way.
Because trenchless construction methods require little digging, the time to rehabilitate the work area to as-found or better condition is decreased.
With decreased disturbance, projects using trenchless methods take less time to complete. Less time means less inconvenience associated with a construction project.
ISTT’s 36th Annual International No-Dig Conference and Exhibition will be hosted by the Southern African Society for Trenchless Technology (SASTT) and is to be held on the 8-9 October 2018 at the Cape Town International Convention Centre (CTICC), South Africa.
