Slide Welcome to the Southern African Society for Trenchless Technology

The Southern African Society for Trenchless Technology was founded to help inform the public, as well as any interested parties, on the workings and benefits Trenchless Technologies bring to our ever-expanding communities and the role it plays in the development of our country.

What is trenchless technology?

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.”

What are the Benefits of Trenchless Technology?

Environmentally Friendly

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.

Minimal Disturbance to Surroundings

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.

Decreased Rehabilitation Time

Because trenchless construction methods require little digging, the time to rehabilitate the work area to as-found or better condition is decreased.

Saves Time

With decreased disturbance, projects using trenchless methods take less time to complete. Less time means less inconvenience associated with a construction project.

No Dig 2019

We are looking forward to a full-house. Neil Van Rooyen will deliver his paper on Unlocking Economic Gro SA using Trenchless Technology, indicating how we can create 100,000’s of new jobs as well as 100’s of new embracing this technology at a national and local government level.

No Dig 2018

The International No Dig conference was held in Cape Town, South Africa from 8-9 October 2018 and was hosted by the local organising branch, the Southern African Society for Trenchless Technology (SASTT).
