Discover our extensive product range and find the right solution for your project — efficient, safe, and state-of-the-art.
Tunnel construction
In tunnel construction, we offer proven solutions for anchoring, sealing, backfilling, and consolidation—both in mechanical and conventional tunneling. Our specialized systems provide permanent and reliable support for structures, even under challenging geological conditions.
Civil engineering
Civil engineering forms the foundation of our infrastructure—where structures are built below the earth's surface. We offer coordinated solutions ranging from excavation pit safety to soil stabilization."
Hydraulic engineering
Our injection systems offer proven solutions for waterproofing, stabilizing, and reinforcing hydraulic engineering structures. They reliably protect dikes, dams, riverbeds, and bank structures against water pressure and scouring.
Structural engineering
In building construction and civil engineering, our injection systems secure demanding infrastructure structures – from bridges and tunnels to drinking water reservoirs and complex industrial constructions.
Special civil engineering
For complex foundation and shoring projects, we provide reliable system solutions for sealing diaphragm walls, sheet pile walls, and bored pile walls, as well as for soil consolidation and subgrade stabilization.
Transport infrastructure construction
We consolidate building sites, stabilize railway tracks, and renovate bridges and concrete roadways—for sustainable, stable roads, railways, and transportation infrastructure.
Mining
Our injection systems ensure the stability of underground facilities in both active mining and the remediation of old mines. We secure and backfill large-volume cavities, reliably seal tunnels and shafts against water ingress, and stabilize unstable rock formations.
Renovation & repair
In building repair, we retrofit existing structures with waterproofing and stabilize load-bearing structures. Our system solutions enable the cost-effective restoration of the functionality, load-bearing capacity, and durability
of buildings, even under demanding conditions or with changing loads.
Fields of application
Anchoring • Sealing • Backfilling • Consolidating • Renovation
We offer comprehensive system solutions for demanding civil engineering and geotechnical engineering projects.
Our core competencies lie in the systematic consolidation of unstable rock formations and loose rock, the permanent sealing of structures against water pressure, and the safe and economical backfilling of large-volume cavities or crevices.
Using specialized anchoring technology for rock stabilization and innovative injection methods for structural repair, we ensure the preservation and functionality of complex infrastructure structures in tunnel, mining, and special civil engineering. To meet these demanding challenges, we supply a precisely coordinated portfolio of construction chemical injection materials consisting of polyurethane and epoxy resins, acrylate gels, and silicate resin systems.
This product range is complemented by high-performance injection technology such as injection equipment, data recording, injection anchors, and injection accessories.
With our many years of experience, we provide worldwide support with in-depth personnel expertise and application technology consulting – from planning to the successful implementation of projects in the areas of anchoring, sealing, filling, stabilizing, and renovation.
