Working at ever greater depths with potentially unstable strata increases the need for enhanced personnel safety within the mine environment. Master Builders Solutions offers a wide range of rock bolting solutions: the portfolio includes ready-to-use cementitious products and admixtures for OPC based grouts to adjust the behavior in terms of shrinkage compensation, corrosion protection, pumping capacity, and bond improvement. Our new MasterRoc RBA 38X line of pumpable thixotropic resins has been designed to offer significant benefits over traditional bolt fixing methods, saving time and improving mine operator safety during the installation and reducing the risks of bolt failures during their expected lifetime.

High-quality, durable sprayed concrete (shotcrete) has become a vital component of ground support and stabilization in both tunneling and mining. The Master Builders Solutions portfolio provides a wide range of superplasticizers for all needs which improves the pumpability and workability performance of sprayed concrete mixes in the fresh state while reducing permeability and increasing density and long-term strength performance in the hardened state.

In hard and soft rock mining, changes in humidity and temperature affect weak strata, causing rock falls and rib degradation. Effective surface support and the protection against weathering of rock and strata are critical to the safety, efficiency and longevity of any mining operation. Master Builders Solutions provides systems for supplementary surface support to strategic areas of a mine. MasterRoc TML (thin mortar liner) is a range of cement-based mortar which has an excellent bond to concrete, rock and coal and can be sprayed using simple to operate equipment. MasterRoc TSL (thin spray-on liner) range provides products based on polymers which allows them to be used in thin layers supporting the strata.

Unexpected water ingress and poor ground conditions can cause significant delays and escalate costs. To counteract these risks, an economical approach is to pre-inject the ground ahead of the advancing face. MasterRoc MP microcements provide extremely effective penetration into fine cracks in rock and fine-grained soils to give efficient water tightness, stability and durability. Master Builders Solutions' fast reacting and non-water-sensitive polyurethanes and polyurea silicate systems quickly stabilize poor ground and are suitable for strata consolidation and rock reinforcement. Our post-excavation injection technologies counteract risks and challenges like instable ground conditions by offering a comprehensive range of injection solutions and technical support.

Backfill operations represent 25 to 30 percent of the overall mining costs. Thus, optimization of the backfill process leads to significant total mining cost reductions as well as improved mining production. The Master Builders Solutions team takes a scientific approach to this challenge that can help mining companies understand and run backfill operations at lower risks and lower costs with higher efficiency through our tailor-made chemistry and backfill expertise.

As a full-range supplier of repair and protection products, Master Builders Solutions offers customized solutions for concrete structures as well as support for the evaluation of the causes of structural damage. Being certified by independent testing institutes in compliance with national and/or international standard requirements, the system solutions help customers to extend the service life of their construction and, lastly, make a significant contribution to sustainability.

Our admixtures aid in the production of high-strength, durable concrete – a prerequisite for complex structures. They are allowing the concrete to flow, thus increasing performance and making it easier to use. They also aid in the curing process of the concrete, preventing the concrete’s components from segregating. After curing they leave the concrete with a smooth and clean surface – and ensure an extremely long service life for the structure. The increased energy efficiency, higher concrete durability and better construction process contribute to reducing CO_² emissions and save time and costs.
