Underground Infrastructure Repair & Waterproofing
Subways, utility tunnels, basements, and underground parking structures are constantly exposed to groundwater pressure, limited ventilation, and difficult access. Our underground infrastructure repair service is designed to stop leaks, restore concrete, and extend the life of below‑grade assets without major disruption.
Problems We Solve
- Water ingress through walls, slabs, and construction joints in below‑grade structures
- Chronic dampness, standing water, and mold in basements and service corridors
- Leak‑related damage in subway tunnels, utility galleries, and underground parking
- Failed membranes where excavation or full replacement is not feasible
How We Fix It
We combine condition assessment with targeted injection and repair:
- Non‑destructive testing and leak path mapping to understand how water is entering
- High‑pressure injection of EURAS® Gel Type B into cracks, joints, and voids—even under active leaks
- Concrete repair and spalling restoration where reinforcement has been exposed or weakened
- Integrated waterproofing systems (membranes, coatings, drainage) where appropriate
Where This Is Used
- Subway and metro systems
- Utility and service tunnels
- Underground parking and commercial basements
- Water and wastewater galleries

Next Step
For owners and operators of underground infrastructure, we can provide a phased repair plan that prioritizes the highest‑risk areas and delivers durable waterproofing with minimal interruption to service.
