Shrinkable Inner Core System
Specially engineered internal core contracts mechanically or hydraulically post-curing, allowing effortless, damage-free core extraction without cracking concrete edges.

Mould
Modular Precast Concrete Box Culvert Mould
Engineered for heavy civil infrastructure and stormwater management projects, our Modular Precast Concrete Box Culvert Mould produces high-strength, monolithic precast box culverts. Constructed from IS 2062 / Q235 structural steel and reinforced with heavy ISMC channels, this mould features a mechanical or hydraulic shrinkable inner core and precision slurry-tight seals to deliver fast cycle times, zero concrete honeycombing and a smooth mirror finish.
Box Culvert Mould is also requested as RCC box culvert shuttering or precast box culvert formwork. Specify clear opening, segment length, slab thickness and inner-core release to compare the correct configuration.
Manufactured by Paras Steel Industries in Gondal, Gujarat, this solution is available for customers across India with custom configuration support based on drawings, dimensions and production requirements.
Starting price
₹115/ kg + GST
Rate per kilogram of fabrication; total mould cost is quoted for the complete configuration. Final price depends on size, design, material, thickness and transport requirement.
Key Features & Benefits
Specially engineered internal core contracts mechanically or hydraulically post-curing, allowing effortless, damage-free core extraction without cracking concrete edges.
Reinforced with heavy ISMC channel stiffeners and angle plates to resist heavy hydrostatic pressure and high vibration without shape distortion.
Precision-machined wedge locks, heavy alignment pins and seal gaskets eliminate slurry leakage for sharp edges and high-quality concrete surfaces.
Universal modular shuttering allows operators to adjust wall thickness, culvert height or length using bolt-on extension panels.
Equipped with heavy-duty mounting plates for external shutter vibrators and pneumatic vibrators, ensuring complete air compaction and dense concrete structure.
Highway underpasses, railway culverts and road crossing culverts.
Stormwater drainage systems, stream enclosures and canal crossings.
Underground service tunnels, utility ducts and industrial pipe corridors.
Industrial modular precast concrete box culvert mould with shrinkable inner core, IS 2062 steel, 6 mm - 8 mm plates, slurry-tight seals and adjustable sizing. Dimensions and configuration can be discussed based on your project requirement.
