Why Saudi Arabia and the United Arab Emirates Import Sand

Saudi Arabia and the United Arab Emirates import sand because not every type of sand is suitable for concrete, glass and major engineering works. Desert sand, shaped by wind, generally consists of grains that are too fine, smooth and rounded, which weakens its bond with cement. To build skyscrapers, roads, artificial islands and urban megaprojects, these countries require more angular sand, typically found in rivers, quarries and particular mineral deposits.

Why do countries surrounded by deserts buy sand?

The answer lies in the texture of the grains. Desert sand is weathered by the wind over thousands of years, becoming rounded and polished. In concrete, these grains do not interlock effectively, behaving like small loose spheres within the mix.

The construction industry requires sand with more irregular particles. Such grains lock together more efficiently, bond to cement and help create a stronger material. As a result, having vast dunes nearby does not mean there is an ideal raw material for buildings, bridges or heavy infrastructure.

What is the difference between desert sand and construction sand?

Construction sand usually comes from riverbeds, regulated coastal areas, quarries or crushed rock. Its grains are rougher, more angular and have a grading better suited to mortar, concrete and precast components.

In practice, the distinction is evident in four important ways:

• Desert sand is smoother and reduces adhesion within the mix.
• River or quarry sand has more angular grains and improves compaction.
• Concrete needs particles with controlled sizes and shapes to achieve strength.
• Very fine sands can increase the amount of water and cement required on site.

What drives sand demand in the Gulf?

Saudi Arabia and the United Arab Emirates sustain high demand for sand because of urban developments, infrastructure, tourism, ports, motorways, artificial islands and projects linked to economic diversification. The expansion of cities such as Dubai, alongside Saudi plans for megaprojects, increases this pressure further.

For projects on this scale, materials must comply with technical specifications. A tower, airport or bridge cannot rely on unsuitable sand simply because it is available in the neighbouring desert. The logistics involved in importing sand therefore become part of construction costs.

Where does the imported sand used by these countries come from?

Some of the sand used in the Gulf is sourced from countries with deposits suitable for industrial and construction use. Australia, China and European countries frequently feature in this trade, depending on the type of sand, its mineral purity and the intended application.

These imports are not used solely for standard concrete. Certain sands are used to manufacture glass, filters, industrial moulds and specialist materials. Every application requires different properties:

• More angular sand for structural concrete.
• High-purity silica sand for glass and industrial applications.
• Washed and graded sand for mortars and finishes.
• Crushed aggregates to replace some natural sand in particular projects.

Why is this dependence an environmental concern?

Global sand extraction is already placing pressure on rivers, beaches, deltas and coastal ecosystems. When construction consumes enormous volumes, unregulated removal can lead to erosion, habitat loss, changes to currents and lower biodiversity in sensitive areas.

The most widely discussed alternatives include manufactured sand, construction-waste recycling, the use of crushed aggregates and concrete with more efficient formulations. The Gulf paradox demonstrates that sand is not a simple resource: its value lies in its shape, origin, purity and ability to support construction without shifting the impact to the rivers, beaches and communities that supply it.
