Horizontal directional drilling for Nuclear Containments

Trenchless crossings for safety, precision and minimal site impact

Nuclear facilities require the installation of pipes, ducts and services under strict safety, environmental and operational constraints. Excavation near sensitive structures, radiation-controlled areas or operating facilities is often limited or prohibited. Horizontal directional drilling (HDD) enables underground crossings without open trenches, ensuring precise installation while preserving existing structures and site safety. VSL delivers HDD solutions adapted to nuclear regulations and complex ground conditions.

Why horizontal directional drilling for nuclear containments

Nuclear containment sites often require underground crossings beneath existing buildings, safety barriers or protected zones. HDD allows pipes and services to be installed along controlled trajectories without disturbing surface structures. This trenchless method reduces risks, limits environmental impact and ensures compliance with nuclear safety and operational constraints.

HDD avoids open excavations near sensitive nuclear structures.

Controlled drilling paths ensure precise alignment and depth.

Reduced interference with existing facilities and operations.

Suitable for variable soils and constrained underground environments.

Methods meet strict safety, quality and documentation standards.
