Betongducts

Betongducts, or concrete ducts, are concrete conduits embedded within concrete structures to route and protect pipes, cables, or other services. They provide dedicated channels that can be embedded in floors, walls, or foundations, allowing services to pass through concrete with reduced risk of damage and easier maintenance.

Construction and design features vary, but betongducts are typically made of reinforced or prestressed concrete. Cross-sections can be circular or rectangular, and some designs incorporate a plastic liner or inner sleeve for smoother cable passage and added protection. Joints between duct segments are sealed to limit moisture ingress and to maintain structural integrity. Ducts may be prefabricated as modular units or cast in place as part of the concrete element.

Installation and use involve planning routes for electrical, data, or other services before or during concrete placement. Ducts are laid out according to architectural and structural plans, and access openings or removable covers are provided at intervals to enable future pulling or replacement of cables. Proper alignment and spacing are important to prevent cracking of the surrounding concrete and to ensure easy maintenance access.

Applications commonly include electrical and communication cabling within buildings, tunnels, and bridges, where betongducts protect cables from moisture, abrasion, and fire exposure while enabling easier replacement or upgrade of services. They also help organize service routes and reduce damage during construction and retrofit work.

Standards and specifications vary by region, but typical requirements address cross-section size, wall thickness, reinforcement details, joint sealing, fire resistance, and integration with surrounding concrete. Coordination with structural and electrical design is essential to ensure proper fit and performance.
