Renovation of aging tunnel structures or subway systems
Many tunnel and subway systems need modernization after decades of use – whether due to new safety standards, outdated technology, or structural damage.
As an international partner, we support complex renovation projects on site and ensure safe, sustainable results with our innovative solutions. In Tbilisi, we carried out block joint sealing, crack repair, and cavity filling in an existing subway line – a successful example of our global expertise in infrastructure construction.
Our Solutions:
WILLPUR® CS – Thanks to its elastic properties and relatively low viscosity, this injection resin efficiently fills and stabilizes cracks and joints in concrete, enabling quick and durable repairs.
WILLPUR® WX – Used for hybrid injection, this high-strength polyurethane offers excellent compressive strength and is applied in precise proportions to enhance the performance of cement-based injections.
