01 — Products
Five product lines, cast to spec.
From highway U-drains to retaining systems, every line is cast under factory control in high-performance grades from M50 to M75.
01
T25 U-Shape Drain
Heavy-duty precast U-drain rated to carry T25 wheel loads. Built for highways, crossings and industrial roads where traffic runs over the channel without flexing.
T25 Heavy duty M50

02
T6 U-Shape Drain
Light-duty precast U-drain for footpaths, plazas and low-traffic streets. The same sealed, smooth bore in a leaner T6 section that lays fast and stays maintenance-free.
T6 Light duty M40

03
FT Flume U-Drain
Trapezoidal FT flume cast as a precast U-drain. Moves water cleanly across canals and irrigation runs with a smooth, silt-free bore over long field lengths.
Trapezoidal Irrigation M40

04
Box Culvert
RCC box culverts move water and services under road and rail without disrupting the line above. Single or twin cell, sized to the hydraulic load and dropped straight into the trench.
1000 × 1000 Single / twin RCC

05
Earth Retaining Wall
Modular precast retaining systems hold ground and stop erosion on embankments, slopes and approach roads. Interlocking units stack quickly and carry load from day one.

02 — Who we are
Since 2005, we've grown from a single Surat yard into a precast partner building the future of Bharat — one drain, culvert and wall at a time.
We work with the engineers, contractors and government bodies shaping India's roads, railways and cities. Our role is quiet but load-bearing: precise concrete that's already cured, tested and ready the day it reaches site.
Mission
Become India's most trusted precast manufacturer — setting the standard for strength and sustainability.
Vision
By 2030, lead the world in precast concrete, known for durability, innovation and responsible building.

What sets our precast apart.
Quality you can test, capacity you can plan around, and a delivery date we keep.
NABL-accredited laboratory
Concrete and materials are tested in our own accredited lab, inside the plant, before anything is dispatched.
Certified and licensed
ISO 9001, ISO 14001 and ISO 45001 certified, with every licence the plant needs, including GPCB consent.
In-house R&D and mould making
Our own team designs sections and makes the moulds — so custom work is as repeatable as our standard lines.
Large capacity, pan-India network
Two Surat plants cast up to 610 tonnes a day, with a third plant coming up in Delhi NCR.
Delivery dates we keep
Units are cast, cured and stacked to your programme, then delivered to site on the date we commit to.
Good finish, batch after batch
Steam-cured, fair-faced concrete with sharp edges and a smooth bore — the finish contractors ask for by name.
04 — From mould to site
Cast in a controlled yard. Checked at every step.
Every unit follows the same route through our plant — so the tenth thousand is as good as the first.
01
Design
Section design & mould
Our R&D team details the section and reinforcement, and the moulds are made in-house for a clean demould.
02
Material check
Raw material inspection
Every truck of sand and aggregate is checked by our QC engineer to the IS code before it is allowed to unload.
03
Batching
Batching & casting
Three RMC plants — Schwing Stetter and KYB Conmat — batch M50 to M75 mixes with RO-treated water.
04
Curing
Automatic steam curing
Units cure in a fully automatic steam-curing system instead of water curing, for consistent strength on a fixed cycle.
05
Testing
Testing in our NABL lab
Cube, slump, V-funnel, rebound hammer and core tests, with independent third-party testing on top.
06
Dispatch
Stacking, loading & delivery
EOT cranes from 3 to 15 tonnes and eight hydra cranes stack and load units for delivery straight to the trench.
05 — Manufacturing
Two plants in Surat. A third coming up in Delhi NCR.
Steam-cured, factory-controlled casting at a scale that keeps national projects on programme.

09 — Sustainability
Precast is the quieter way to build.
Casting in a controlled yard — not on an open site — means less waste, less disruption, and concrete that lasts long enough to stay out of a landfill.
Less waste, by design
Factory casting reuses formwork and reclaims water, cutting the spillage and offcuts of site-poured concrete.
Built to outlast
M50–M75 mixes resist abrasion and corrosion, so a drain or culvert serves for decades without rework.
Faster, cleaner sites
Precast arrives ready to set — fewer machines, less dust and noise, and far shorter road closures.
M75
Peak concrete grade — engineered for a maintenance-free service life.
10 — Clients
