HelCor®
Helically Corrugated Steel Pipes
HelCor® pipes are the backbone of ViaCon’s culvert solutions. Designed for roads, railways, and hydrotechnical projects, they enable fast installation and significant cost savings compared to concrete alternatives. With decades of proven use worldwide, HelCor® ensures reliable performance across a wide range of infrastructure applications.
HelCor+®
Enhanced Polymer-Coated Steel Pipes
HelCor+® takes the proven HelCor® system a step further with TrenchCoat® polymer film coating applied over galvanized steel. This advanced protection ensures durability in aggressive environments, making it ideal for electrified railways, wastewater exposure, and chemically demanding conditions.
ViaPlate® 200
Modular Corrugated Plate System
ViaPlate® 200 is a flexible soil-steel structure engineered for bridges, culverts, tunnels, and ecological crossings. Its modular corrugated plates, precision bolt connections, and engineered foundations enable spans up to 12 meters, multiple cross-sectional shapes, and long-lasting structural performance — even under demanding site conditions.
