Deep concrete technology to support underground projects

From the world's largest underground copper operations in Chile and Australia to gold mines in Canada, United States and Mexico, leading mining companies rely on TYTRO® to reduce their operating costs, minimize excavation downtime, achieve desired technical performance and meet the highest safety standards.

Our world-class field technical specialists combine a deep concrete technology knowledge with strong technical application expertise to offer significant, measurable improvements in cost, performance, quality and safety of shotcrete operations.

Solving coal mine stability problems with De Neef® Organosol grouts

Coal mines sometimes have to deal with very poor top and floor conditions in parts of the mine. These challenges can be solved by stabilizing the gob that accumulates on top to the longwall machine as well as preventing the sloughing off the top directly above the coal face ahead of the shields by injections with De Neef® polyurethane and organo-mineral grouts to fill the voids and re-bond the strata.

Mining projects achieve higher efficiency and productivity with the TYTRO® shotcrete system

Across Australia, North America, Western Europe and Latin America, contractors have used our TYTRO® products on major mining projects.

Adopted in South America's largest hard rock mines, TYTRO® has quickly become the leading solution in both mining and civil construction projects in Latin America. Among the key benefits: significant gains in productivity and cost advantages.

We have deep experience in underground construction, including some of the largest and deepest underground mine projects in Australia, Chile and Canada. Wherever projects take you, our team of world-class field technical specialists can work with you on-site to ensure you get an efficient mix that suits your project needs.

Top mining companies rely on the TYTRO® system in their global underground operations

The underground mines are located in Northern Queensland, Australia. They include one of the world's largest underground copper mines with shafts that reach 1,800 meters underground.

Our regional team of shotcrete experts and support staff worked closely with the mine's ground support operations personnel. Together, the teams developed an optimized mix design with the full TYTRO® admixture system.

By adopting TYTRO®, the mine’s ground support team realized major savings with material costs coming in 10% lower than other options and rebound levels down to single digits while enhancing quality and safety for the site. They also were able to accelerate drilling cycles by one to two hours. The solution? A high-performing, optimized mix design that allowed for the faster early strength value needed to re-enter the excavation face and proceed with bolting operations.
