The objectives of the Summits are to promote the wider use of Trenchless Technology and to assist the international community with educational and interactive forums. The focus of each Summit is the ISTT Trenchless Masterclass - a program of presentations from international experts Samuel Ariaratnam and Dec Downey. The papers will present in-depth knowledge on many aspects of trenchless installation and repairs. Case study presentations to complement the Masterclass topics will also be included in the program.
