Sovereign has successfully completed numerous Tunnel and Shaft Grouting projects across 5 continents over the past 4 decades.
The Sovereign Group is the leading grout group approved by major parastatals throughout the world and Tunnel and Shaft Grouting has been undertaken on many major projects.

Tunnel and Shaft Grouting has been performed in the way of pre-grouting in advance of the excavation by curtain grouting and/or reactive grouting during or following tunnel and shaft construction.

Shaft grouting is undertaken so that lining repairs in the form of shotcrete, concrete and steel linings/tubbing’s can be installed.
