We are highly experienced in pneumatic stowing to provide positive void filling. In 85 years of work we have filled vaious sizes and types of underground mine entries, shafts, aguer holes and washout cavities. We have placed thousands of cubic yards of aggregate and grout of all sizes. We can help your company with a solution to fill any type of void, even in remote and limited access situations. Through pumping, conveying, or stowing, Gunite provides cavity filling at a fraction of the cost of excavation. Our patented methods of mixing and placing material have a minimal impact on surrounding jobsite environments.
