Box culverts
High-performance units for underpasses, crossings and small bridge openings, with water-tight jointing and predictable site fit.
Class 70R / A / AA | Railway loading | ±5 mm dimensional control
Box culvert in context
Reference views for sizing conversations and site planning.
Box culverts need to look strong and perform stronger. Our precast units are designed for Indian highway and railway loading classes, cast with high-performance self-compacting concrete for durable, water-tight structures that go in ready for installation.
Close manufacturing tolerances (segment length and edges within about ±5 mm, thicknesses about ±3 mm) mean predictable fit on site — plug-and-socket joints, mortar and gasket grooves, and flange-bolt connections that keep segments aligned under construction loads.
Reinforcement and concrete grades follow project design (including Fe500D / Fe550D options and durability-focused steel where specified), so each run matches the load case your engineer signed off — Class 70R, Class A, Class AA, or railway categories.
