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.

Providing high quality smart concrete products and services. Mfg. of U Shape Drain, Cable Trench, Box Culvert, and All Customized Precast Products.

More about Trilok

— Our mission

Mission

To rise as the leading precast concrete manufacturing company, setting unparalleled standards in strength and sustainability. We are on a journey to construct a future-ready world.

— Our vision

Vision

By 2030, we aim to be recognized as India's premier precast concrete manufacturing leader, setting benchmarks with our superior and sustainable products. We are dedicated to serving vital sectors, including Power, Water & Sewage, Railways, Industrial, and Roads & Bridges, as we lay the foundation for a resilient and progressive nation.

03 — Why Trilok

What sets our precast apart.

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.

Design

Section design & mould

Our R&D team details the section and reinforcement, and the moulds are made in-house for a clean demould.

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.

Batching

Batching & casting

Three RMC plants — Schwing Stetter and KYB Conmat — batch M50 to M75 mixes with RO-treated water.

Curing

Automatic steam curing

Units cure in a fully automatic steam-curing system instead of water curing, for consistent strength on a fixed cycle.

Testing

Testing in our NABL lab

Cube, slump, V-funnel, rebound hammer and core tests, with independent third-party testing on top.

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.

09 — Sustainability

Precast is the quieter way to build.

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.

Our approach

M75

Peak concrete grade — engineered for a maintenance-free service life.
