Cut-off walls for nuclear containment structures

Groundwater control for safety, durability and long-term performance

Groundwater control is a critical requirement for nuclear containment structures. High water tables, permeable soils and hydraulic gradients can compromise foundation stability and long-term durability if not properly managed. Cut-off walls create an effective hydraulic barrier that limits water ingress, controls seepage and protects nuclear facilities. VSL delivers engineered cut-off wall solutions designed to meet stringent nuclear safety, quality and regulatory requirements.

Why cut-off walls for nuclear containments

Nuclear containment structures often require strict control of groundwater to prevent uplift pressures, erosion and long-term degradation. Cut-off walls reduce permeability around foundations, limit seepage paths and stabilize hydraulic conditions. They contribute to predictable soil–structure interaction and help ensure compliance with nuclear safety and environmental regulations.

Cut-off walls significantly reduce water inflow and seepage.

Controlled hydraulic conditions limit erosion and uplift risks.

Reduced water ingress protects concrete structures over time.

Solutions are effective in permeable and heterogeneous soils.

Design and execution meet strict safety, quality and traceability standards.
