Did You Know?
Over 2,000 years ago, Chinese engineers built parts of the Great Wall of China using a mortar made from sticky rice — and many of those sections are still standing today.

The Secret Behind Sticky Rice Mortar

During the Ming Dynasty, builders mixed slaked lime with glutinous rice soup. The result? A strong, water-resistant adhesive compound that bonded stone and brick more effectively than traditional methods. Researchers have found that this ancient “organic-inorganic composite mortar” even withstands earthquakes and centuries of erosion.

The Lesson for Today’s Engineers

At PrimeStar Group, we believe civil engineering is about more than bricks and concrete. It’s about:

Applying timeless construction wisdom

Embracing modern innovation

Choosing materials and methods that ensure long-term performance


Just like sticky rice mortar helped build a legacy, we aim to create infrastructure that lasts — no shortcuts, no compromises.

Building with Integrity, Every Step of the Way

From foundations to roadworks, our civil engineering teams follow a simple principle:
Do it once. Do it right. Build it to last.

Every PrimeStar Group project is guided by careful design, tested engineering principles, and attention to the smallest construction detail — because what we build today is meant to serve generations tomorrow.

Let’s Build Something That Lasts

Whether you’re planning large-scale construction, industrial infrastructure, or long-term maintenance — our expert civil engineering division is ready to deliver.
