Skilled Services and Processes used in construction projects:

Shotcrete: A process where concrete is conveyed through a hose and pneumatically projected at high velocity onto a surface, as a construction technique. Shotcrete undergoes placement and compaction at the same time due to the force with which it is projected from the nozzle. It can be impacted onto any type or shape of surface, including vertical or overhead areas.

Rock Bolting: the installation of a threaded bar or a tendon drilled into a whole into rock to bolt a loose piece rock onto stable substrate.

Soil Nailing: the reinforcement of the soil by drilling holes and installing a tendon commonly a threaded bar or a cable and then fastened onto the these sure surface and the tension soil surface under tension

Micro-piling: Micro piles can typically be installed using small scale piling rigs able to work in limited access or for low headroom piling. It can be used for foundation upgrades, refurbishment works, temporary and permanent piling applications for both tension and compression loading and are well suited to a wide variety of ground conditions. They can be installed with small piling rigs and can be raked or angled

Micro-fine Cement Injection: Cement grouts suitable for pressurised soil permeation injection. There are many different types of permeation cement grouts and manufacturers. Some are designed for varying types of void filling; others are designed for differing degrees of soil permeation

Grout Compaction: Compaction grouting uses low mobility grouts to rapidly improve discrete zones of soft or loose soils. The method provides a low cost, low risk solution for underpinning, liquefaction mitigation and re-levelling of buildings back to their original elevation. It can be used on large projects using high capacity plant as well as with hand tools, allowing improvement to be carried out in the most restricted locations.
