Mining & Tunneling
Chemical solutions for underground constructionBASF is a world leader in the provision of safe, reliable, cost efficient, and customer-oriented chemical solutions for the mining and tunneling industries.
In addition to a wide range of products, our globally connected team offers customers excellent technical support on site.
Our comprehensive portfolio includes solutions for:
Chemical, Mineral & Cementitious Grouting
Pre-Injection and Post-Injection TechnologiesUnexpected water ingress and poor ground conditions during mining and tunneling operations can cause significant problems for underground contractors. Pre-injection and post-injection technologies from BASF offer high-performing chemical and non-chemical products suitable for:
- Water and crack sealing, void-filling
- Strata stabilization, ground consolidation, structure repair
Mine stability after placementMine backfill technologies help to provide an optimum balance of high early strength and sustainable long term strength, ensuring dimensional stability after placement to meet or exceed design fill performance requirements. BASF’s range of MasterRoc backfill admixtures can help customers challenge conventional physical limitations by:
Improving backfill durability
Controlling retardation, acceleration and rheology
Modifying viscosity, reducing yield stress and pumping pressures.
Precast Concrete Tunnel Segments
State-of-the-art technologies for high quality, durable concrete tunnel segments
This high-range water reducing admixture is based on the new generation of polycarboxylate technology that incorporates state-of-the-art molecular engineering to provide fast wet-out of powder materials. Benefits to concrete production are:
Rapid cement dispersion
Superior early and ultimate strengths

Tunnel Boring Machine
Improve operational efficiency in TBM excavation
BASF's comprehensive tunnel boring machine products improve operational efficiency in soft ground and hard rock TBM excavation. We help you meet your biggest challenges from the start of your project by offering:
Laboratory resources for project specific testing
Technical consulting for every stage of your project
Underground Water Management
Sprayable membrane for waterproofing concrete structures
Spray-applied membrane can be applied between layers of sprayed or cast-in-place concrete, or applied as a stand-alone membrane, exhibiting high bond strength to the substrates on both sides of the membrane.
High bond strength to substrates
Innovative Solutions for Strata Control
BASF offers a wide range of rock bolting solutions that facilitate safe ground stabilization while improving mine productivity. Developed for placement of cable and rock bolts in underground mines, our innovative solutions improve cycle times for both cable and rock bolt installation, while increasing worker safety and strata control.
Besides reactive resins from the MasterRoc RBA 38X range the portfolio includes also ready-to-use cementitious products and various admixtures for OPC based grouts to adjust the behavior in terms of shrinkage compensation, corrosion protection, pumping capacity, and bond improvement.
MasterRoc RBA 380: compact thixotropic polyurea silicate injection resin, specifically designed for rock and cable bolt installations
MasterRoc RBA 387: fast reacting compact thixotropic polyurea silicate injection resin suited for self-drilling anchors and automated installation
