Founded in 1986 by Graham Nordsvan, GSC leverages decades of experience in Hard Rock Mining and Tunnelling to create innovative shotcreting solutions, including the industry-leading polyurethane 3-stage nozzle system and Universal and European Mounting pipes. GSC’s standout products, such as the patented Depth Gauge, deliver unmatched precision, efficiency, and cost savings, solidifying its reputation as a leader in shotcrete innovation.
GSC’s Depth Gauge System is a game-changer for the mining and tunnelling industries, offering unmatched precision in shotcrete application. Designed for accuracy and ease of use, the system allows operators and engineers to measure shotcrete thickness in real-time, eliminating guesswork and ensuring compliance with project specifications. The base plate is securely mounted to the wall or rock face, with 25mm extension pieces that lock in place to achieve the required depth.
This modular design allows for flexible adjustments, ensuring optimal material usage while reducing overspray, saving both time and costs.
We specialise in Hard Rock Shotcreting and have designed a three-part Polyurethane Nozzle System that prioritises safety, performance, and quality. This innovative system is cost-effective, lightweight to reduce strain on machinery, easy to install, and simple to clean and maintain.
GSC’s universal mounting pipe is compatible with nearly all shotcrete machines and is available in two types: Universal and European.
Manufactured in Australia, GSC keeps ample stock to ensure rapid delivery, with orders dispatched within 24 hours. Competitors often import products, causing lengthy delays due to low or no stock availability.
GSC’s high-quality, durable nozzles reduce the number required for operations, saving customers significant costs and minimising inventory needs, which lowers associated tax burdens in Australia.
GSC’s advanced nozzles streamline concreting by evenly mixing shotcrete, chemicals, and water, resulting in faster application, reduced chemical wastage, and uniform consistency, while also preventing blockages and ensuring efficient operations.
Made from clear polyurethane, GSC’s nozzles are lightweight, easy to clean, and allow blockages to be quickly identified and resolved. A safety wire prevents loss if the Nozzle detaches, extending nozzle lifespan and improving operator safety.
The three-part nozzle system, designed and patented by GSC, uses less air demand, making it ideal for mines, while its lightweight design reduces strain on machinery and is easier for operators to handle safely.
GSC’s accessories enhance efficiency, extend nozzle life, and improve safety, including a safety lug and stainless steel wire attached directly to the Nozzle that provides better rebound control and helps minimise time and costs during mining operations.
GSC’s patented Depth Gauge System offers significant cost savings by ensuring the precise amount of shotcrete is applied, eliminating overspray and reducing unnecessary material usage.
Unlike competitors that rely on costly laser systems or core drilling, GSC’s Depth Gauge provides quick, accurate, and visual checks of sprayed thickness, both during and after the pour.
The Depth Gauge allows for interchangeable thickness settings in 25mm increments, which can be adjusted on-site to accommodate varying requirements, such as drainage at 75mm and walls at 250mm, using the same base system.
