The company

Engineering‑led precast,
made in Saudi Arabia

ModuCast is the precast concrete brand of 3D Builders — a Riyadh contracting and manufacturing company that builds what it manufactures. We engineer, cast and install single‑pour water tanks and FRC walls & fences in our own yard, in our own steel moulds — engineered in‑house to Saudi Building Code‑compliant specifications and factory‑checked before they leave the plant.

◆

Cast as one piece

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

▲

Engineered & tested

SBC‑compliant structural specification, SABIC‑steel reinforcement and a 48‑hour water‑tightness test on every tank.

01 · Water Tanks

Tanks cast
as one piece.

Cast as a single monolithic unit in the factory around a SABIC‑steel cage, sealed and water‑tested — then delivered and set in your prepared pit, connections cast into the roof and ready to hook up. The most common failure points of traditional tanks are removed by design.

Engineered, not generic

Validated before
it ships

Every tank is manufactured to a Saudi Building Code‑compliant structural specification and shop drawings — C35 concrete at 400 kg/m³ cement, SABIC 12 mm steel, documented member thicknesses, and a 48‑hour water‑tightness test on every unit.

Boundaries,
by the metre.

Fiber‑reinforced concrete panels with FRP bars that never rust, cast off‑site with the finish built in — then lifted and set on your prepared footing, far faster than block‑and‑plaster, with 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 shop drawings confirmed before production — footing design issued on request.

Factory casting

Single‑pour casting in steel formwork — while you prepare the site, pit or footing.

Finish & test

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

Deliver & install

Transported by flatbed and set on your prepared base or footing — units or metres per day.
