      Why Sites Are Moving Beyond Traditional Culvert Shuttering

      Steel culvert shuttering is heavy, needs a crane, and rarely seals cleanly at the base-to-wall junction.
      Plywood boxes leak at every joint and rarely survive more than a handful of pours.

      Nova Box Culvert Formwork was built to remove these problems at the source – a modular
      plastic-and-aluminium panel system engineered to cast the base, walls, and top slab as one continuous,
      leak-proof structure.

      It was developed after studying real site complaints across hundreds of Indian infrastructure projects –
      from highway underpasses to smart city drainage networks. The result is a system that contractors don’t
      just tolerate, but actively prefer.

      See Where It Makes the Biggest Difference

      Highway & Expressway Projects

      Continuous box sections cast without cold joints, keeping underpass schedules on track. Suitable for: Highway underpasses, expressway drainage, flyover box sections

      Smart City & Urban Infrastructure

      Leak-proof, corrosion-free structures built to hold up under decades of water flow. Suitable for: Stormwater culverts, utility corridors, smart city drainage networks

      Railway & Metro Projects

      Precise, repeatable box sections that hold tolerance across long alignments. Suitable for: Railway underpasses, metro box tunnels, level-crossing replacements

      Government & Public Works

      Built to standards that hold up under inspection on national infrastructure. Suitable for: PWD projects, irrigation channels, PSU infrastructure

      BUILT FOR REAL SITES

      Designed Around Real Site Challenges

      We don't just make formwork. We solve the real problems you face on site, every single day.

      THE CHALLENGE
      OUR SOLUTION
      Heavy Steel Shuttering
      Panels are light enough for a small crew to handle by hand. No crane, no heavy machinery.
      Leaking Base-to-Wall Joints
      The pins-and-wedges locking system leaves no gaps between panels, so there's no leakage at any joint.
      Slow Culvert Cycles
      Snap-fit modular assembly cuts erection and stripping time significantly compared to bolted steel or nailed plywood.
      High Labour Costs
      Minimal skill needed to assemble. Site labour can be trained on it within a day.
      Frequent Repairs & Replacements
      No rust, no swelling, no warping - the same panel performs pour after pour.
      Water-Damaged Shuttering
      Plastic-aluminium panels are unaffected by water, humidity, or waterlogged trench conditions.
      Poor Internal Finish
      Low surface tension stops concrete from sticking, giving a smooth internal surface that keeps water flowing cleanly.
      Material Wastage
      Reusable 100+ times, with a Panel Exchange Program that recovers value even at end-of-life.

      Built to Perform
      Across Every Project Stage

      100+ Reuses Per Panel

      Benefit: One-time investment covers dozens of projects

      Business Impact: Lower cost per square metre than steel, aluminium, or timber over the project lifecycle

      Modular Plastic Panels

      Benefit: Base, walls, and top slab cast as one continuous unit

      Business Impact: Eliminates cold joints and reduces leakage-related rework

      Lightweight Modular Panels

      Benefit: No crane, no heavy crew required for handling

      Business Impact: Lower site logistics cost and faster mobilization on long alignments

      Leak-Proof Locking System

      Benefit: No gaps between panels during the pour

      Business Impact: Fewer repairs and callbacks after handover

      Everything You Need in One Modular System

      Modular by Design

      One system, every culvert span and box size - from small drainage runs to large highway underpasses.

      Benefit:

      Less inventory, more flexibility.

      Prefixed Tie Rod Holes

      Come with caps built in - ready to use, or seal instantly when idle.

      Benefit:

      No last-minute drilling or misalignment.

      All-Weather, All-Water Performance

      Performs equally well in salt water, fresh water, or freezing conditions.

      Benefit:

      One system for every site condition, anywhere in India.

      100% Recyclable

      Fully recyclable at end-of-life, reducing the project’s carbon footprint.

      Benefit:

      Supports sustainability goals without compromising performance.

      It's a patented, modular plastic-aluminium formwork system used to cast box culverts as one continuous, leak-proof structure - base, walls, and top slab together.
      It shapes and supports concrete while it sets, forming culverts, underpasses, and drainage channels for highway, railway, and smart city infrastructure projects.
      Panels lock together with a pins-and-wedges system that leaves no gap at the joints, so there's no leakage at the base-to-wall junction or between sections.
      Lightweight handling, 100+ reuses, no rust or corrosion, and a continuous leak-proof pour without cold joints.
      Yes - panels can be assembled by site labour with minimal training, without cranes or welding, even in confined or waterlogged trenches.
      Yes. The plastic-aluminium hybrid design is built to form the full box section as a unified, continuous structure rather than separate pours.

      Steel formwork reduces speed, tires labour, and stretches the day.
