Building a swimming pool on the edge of a cliff can be an exciting and challenging project, especially when using shotcrete as the main building material. Shotcrete is chosen for its strength, durability, and ability to create complex shapes, which is essential for a pool in such a unique location.
SOUTH EAST ASIA JUNGLE TRACK AUCKLAND ZOO
Aqua-Environs Construction was subcontracted to provide shotcrete installations as a part of our broader scope of work: construction services to create a naturalistically themed terrestrial and aquatic habitats for Auckland Zoo’s new South East Asia Jungle Track (SEAJT), the Zoo’s most ambitious project in its 99-year history. Our company utilized shotcrete to help create natural, realistic animal habitat areas as well as public spaces to achieve engaging natural environments for animals and fish in the zoo’s care and for the zoo’s visitors.
SHOTCRETE AT MT PLEASANT STATION
Multi-million dollar underground stations are currently under construction on Metro and LRT lines in Toronto, Ontario, Canada. Traditionally, the thick, heavily reinforced structural concrete station walls have been constructed using the conventional form-and-pour concrete construction method. This construction method, while widely used, is not without its challenges.
Many of the underground station sites are in congested urban areas with limited spaces for laydown of concrete formwork, and crane access time for handling and installation of formwork is often on a critical path for completion of station construction.

The Jetcreter – The First Continuous-Feed, Dry-Mix Gun
During the summer of 1970, on my 18th birthday, my father woke me up and told me they needed me on a job. I drove out that morning in July to the Crucible Specialty Steel plant in Midland, PA. It was my first experience working on a Gunite job. We were gunning refractory in a vessel, and I was throwing 100 lb (46 kg) bags of pre-packaged refractory into a paddle mixer to pre-dampen the material. We emptied the paddle mixer on sheets of plywood and shoveled the pre-dampened refractory material into the dry-mix shotcrete gun’s hopper. The Jetcreter was a continuous-feed gun, and it was tough for us to keep up with it. It was a very long day for me because it took 15 hours to complete the gunning. I left the house that morning in the dark and returned home in the dark. That was my introduction to “Gunite” (now referred to as dry-mix shotcrete).
Shotcrete’s many advantages are seen in creative construction around the world. Shotcrete’s adaptability to local materials, environmental elements, and climates further illustrates shotcrete’s ability to serve on any project. Shotcrete Nozzleman certification is also a respected credential around the world, and more and more countries recognize the American Shotcrete Association’s role in raising the standards for education and application to ensure quality projects.
