Concrete Shafts

Concrete shafts are typically a finished product that is used for access to a deep tunnel or as a sewer or watermain chamber. Technicore has used freezing technology to allow the installation of a lighter primary shaft lining (typically steel ribs and timber lagging) prior to the pouring of the concrete lining which is done while the freeze is still in place.

Technicore is utilizing the data collected from the four shafts constructed by freezing to date to develop a system to pour the finished concrete lining directly against frozen soil thereby eliminating the need for an expensive primary lining completely.
