How It Comes Together

Our Installation Process

From excavation to grouted panel, every Shreeji Precast wall follows the same four-step sequence and the same tested specifications.

4 Steps

Fast & Systematic Installation

01

Excavation

Dig 2 × 1.5 ft pedestals for precise column placement and alignment.

02

Concrete Pour

Pour M-15 grade concrete into the pedestals to form a stable foundation.

03

Column Fixing

Secure pre-stressed M-25 grade columns into the concrete pedestals for structural stability.

04

Panel Slotting & Grouting

Slot panels into column grooves and grout joints for a seamless, strong wall structure.

Why It's Built This Way

The Engineering Behind the Numbers

Reinforcement

Pre-stressed wire, not plain rebar

Panels and columns use high-tensile steel wire under pre-stress rather than standard reinforcement bar. Pre-stressing keeps the concrete in compression under normal loads, which is what lets a roughly 1.7-inch-thick panel resist wind and impact loads that would crack an unreinforced slab of the same thickness.

Concrete grade

M-25 above ground, M-15 below

M-25 grade concrete goes into the columns and panels — the components exposed above ground and doing the structural work — while the buried footing uses M-15, a leaner mix appropriate for a foundation that's carrying compression load rather than resisting bending.

Assembly

A grooved joint, not a fixed one

Panels slot into a groove cast into the column rather than being rigidly fixed, and the joint is then grouted. That groove allows a small tolerance during installation, and makes it possible to replace a single damaged panel later without touching the rest of the wall.

Timeline

Why it's faster, not just cheaper

Because panels and columns are cast off-site in advance, on-site work is limited to excavation, footing, column fixing and grouting — there's no waiting on brick courses to cure one row at a time, which is where most of the schedule on a traditional wall gets lost.
