New market adoption of jacked pre-cast caisson shaft construction methodologies. An overview of the jacked caisson methodology and its' application to varying ground conditions; the ability to deliver water-tight, rationalised structures through soft rock, non-cohesive and cohesive ground. Paired with underpinned, under-reamed and corbeled segments, sprayed concrete linings and concreting under-water, this is a safe, versatile, quick construction methodology that can be designed for near surface infrastructure up to 70 m deep. Pre-cast caisson methodology can also minimise the need for wet process applications on site and assist in reducing site waste streams due to its' predominantly pre-cast system components.
