The company

Engineering‑led precast,
made in Saudi Arabia

ModuCast is the precast concrete brand of 3D Builders. We engineer, cast and install single‑pour water tanks and FRC walls & fences — combining factory quality, faster installation and a predictable price. Every structure is finite‑element engineered and factory‑tested before it leaves the plant.

◆

Cast as one piece

Monolithic single‑pour bodies — no joints, no seams, fewer failure points.

▲

Engineered & tested

SAP2000 finite‑element analysis and a 48‑hour water‑tightness test on every tank.

●

Delivered & installed

Transported and set on site in about an hour, nationwide across the Kingdom.

What we make

Two engineered
product lines

The same DNA — engineered off‑site, fiber‑reinforced, then delivered and installed by the unit or by the linear metre.

01 — PRODUCT LINE

Precast Water Tanks

Single‑pour, FEA‑engineered concrete tanks, 8–25 m³. No joints, fiber‑reinforced, 48‑hr water‑tested, 10‑year warranty.

From 6,855 SAR · ex‑VAT→

02 — PRODUCT LINE

Precast Walls & Fences

FRC boundary panels, 2.4 m, in many architectural finishes with integrated lighting — priced by the linear metre.

388 SAR / linear metre→

01 · Water Tanks

Tanks cast
as one piece.

Cast as a single monolithic unit in the factory, fiber‑reinforced, lined and water‑tested — then delivered and installed on site in about an hour. The most common failure points of traditional tanks are removed by design.

Engineered, not generic

Validated before
it ships

Every tank is 3‑D modelled and finite‑element analysed (SAP2000) for the full water and earth‑load envelope before production — documented thicknesses, verified forces, and a 48‑hour water‑tightness test on every unit.

02 · Walls & Fences

Boundaries,
by the metre.

Fiber‑reinforced concrete panels, cast off‑site and erected by the linear metre — far faster than block‑and‑plaster, with a predictable price and integrated wall lighting. Ideal for compounds, plots, yards and large perimeters.

How we work

From order to
commissioning.

One accountable team takes the project from sizing and structural check through factory casting, testing and on‑site installation — measured in days, not weeks.

Design & engineering

Sizing, layout and structural check (FEA for tanks) confirmed before production.

Factory casting

Single‑pour, fiber‑reinforced casting in steel formwork, in parallel with site prep.

Finish & test

Selected finish or lining applied; tanks pass a 48‑hour water‑tightness test.

Deliver & install

Transported by flatbed and installed under supervision — units or metres per day.
