At F. Willich, we develop products that solve real challenges on construction sites and in technical facilities. Our high-quality systems for insulation, waterproofing, injection, coating, and geotechnical applications are designed to work reliably, simplify processes, and deliver sustainable results.
Whether for new construction, renovation, or demanding special applications, our product ranges offer you exactly the materials you need to protect buildings, stabilize structures, and ensure long-term quality. From high-performance resins and robust surface protection systems to precise solutions for substrates and infrastructure, every product impresses with its high material quality, ease of processing, and proven performance.
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—whether in mechanical or conventional tunneling.
Our systems provide permanent and reliable support for structures under difficult geological conditions.
Civil engineering
Stability begins underground. Civil engineering creates the basis for our infrastructure — where structures are built below the surface. From excavation pit securing and soil compaction to subsoil stabilization, our systems ensure load-bearing, compacted, and permanently sealed building sites. This creates secure foundations for roads, bridges, tunnels, utility networks, and building construction.
Hydraulic engineering
Our injection systems offer tailor-made solutions for waterproofing, stabilizing, and reinforcing structures that carry water. They reliably protect dikes, dams, riverbeds, and bank structures against high water pressure and scouring.
Structural engineering
In civil engineering and specialized civil engineering, our injection systems secure demanding structures—from bridges and tunnels to drinking water reservoirs and industrial constructions. Our solutions enable permanent sealing, filling of cavities, and reinforcement of structures—even under high loads or changing stresses. In this way, we create the basis for safe, durable, and economical structures.
Special civil engineering
For complex foundation and shoring projects, we provide reliable solutions for sealing diaphragm walls, sheet pile walls, and bored pile walls, as well as systems for soil compaction and subgrade stabilization. In tunnel construction — a key component of special civil engineering — we also offer systems for anchoring, sealing, backfilling, and compaction.
Transport infrastructure construction
We consolidate subsoils, stabilize track systems, and renovate railroad ties, bridges, and highway slabs—for sustainably stable roads, railways, and traffic routes. Our lifting injection systems are also used for sunken taxiways and runways at airports—with millimeter precision, quickly, and during ongoing operations. We also use our injection systems to stabilize sunken roads, bridges, and highways—with millimeter precision, quickly, and during ongoing operations.
Mining
In active and abandoned mines, we secure cavities, seal tunnels, and stabilize rock formations — with reliable injection systems for demanding geotechnical conditions.
Renovation & repair
We retrofit existing buildings with waterproofing and stabilize load-bearing structures—specifically in new buildings as well. Fast, safe, and economical.
Fields of application
Injection • Waterproofing • Consolidation • Repair • Anchoring
The fields of application of our products in civil engineering & geotechnology as well as in other areas of construction are the consolidation of soil, rock or raw materials, in the sealing against water, the safe and economical filling of cavities, in anchor technology and the repair of structures.
To solve these often-challenging problems, we have at our disposal not only a range of tried-and-tested grouting and repair products, we also have the necessary products for repair, we also have the necessary injection technology such as injection equipment, data recording, injection anchors and injection accessories.
We would be pleased to support you with our experience and personal know-how, when it comes to anchoring, sealing, backfilling, consolidation and repair, worldwide
