Evaluating Wall Materials for Middle East Projects: Why 80% of Bricks Are Rejected Due to Non-Compliance with Standards
In the Middle East, building structures are typically constructed using concrete or steel frame systems, where the choice of wall materials directly impacts project cost, construction schedules, and building performance. With the advancement of mega-projects such as Saudi Arabia's "Vision 2030" and the UAE's "Centennial 2071," the local construction market has imposed higher requirements on wall materials. However, the disparities in building standards across Middle Eastern countries have become a real challenge for many investors and contractors.
Why Are Your Bricks Failing to Meet Local Acceptance Standards?
Middle Eastern countries are accelerating the internationalization of concrete masonry unit standards to ensure building material quality aligns with global benchmarks. The Gulf Cooperation Council (GCC) has published the latest standard test methods for concrete masonry units (GSO ASTM C140/C140M:2024), covering key indicators such as dimensional measurement, compressive strength, absorption, unit weight, and moisture content. Jordan has approved the ASTM C129 standard for nonloadbearing concrete masonry units, scheduled to take effect in March 2026. The Egyptian standard ES 1292-2 is also technically aligned with ASTM C129, clearly specifying performance requirements for nonloadbearing concrete masonry units.
This means that if even one dimensional tolerance or strength indicator fails to comply with local regulations, your bricks may be rejected at the site. In Middle Eastern EPC projects, acceptance procedures are extremely strict. Once bricks are rejected, it not only means the production capacity cannot be converted into profit but may also lead to a complete halt of the entire project.
Traditional Material Performance Differences: Rammed Earth, Local Bricks, and Factory Bricks
In the Middle East, common wall materials include rammed earth bricks, local bricks, factory bricks, and concrete masonry units (CMU).
Rammed Earth Bricks (CEB)
Rammed earth bricks are relatively low-cost, with the primary material sourced from soil excavated on-site, and uniform brick dimensions that reduce mortar usage. However, quality is highly dependent on soil conditions and manufacturing processes. In the hot, dry Middle Eastern environment, without strict moisture control, bricks are prone to rapid deterioration under direct sunlight and wind.
Local Bricks (Village Bricks)
Local bricks rely on manual firing, with inconsistent dimensions and thick mortar joints during masonry. The firing process also consumes large amounts of wood, conflicting with the sustainable development goals promoted by Middle Eastern countries. In projects with strict standardization acceptance, this type of brick is almost unable to meet requirements.
Factory Bricks
Factory bricks offer stable supply in urban areas, consistent dimensions, and reliable strength, with higher masonry efficiency. However, the overall cost remains higher than concrete masonry units, and long transport distances limit their large-scale application in major projects.
Concrete Masonry Units: The Preferred Choice for Large Middle Eastern Projects
Concrete masonry units (CMU) are becoming the preferred choice for large projects in the Middle East due to their high standardization, structural strength, and construction efficiency. Their core advantages are reflected in the following aspects:
Standardization and Quality Control
CMUs are precisely formed using molds, with uniform dimensions and consistent density, significantly reducing mortar usage. In the Middle Eastern market where standards such as ASTM are strictly enforced, CMUs are more likely to pass acceptance inspections and reduce rework risks.
Structural Strength and Construction Efficiency
At the same building area, CMU walls can be made thinner, greatly reducing mortar and subsequent plastering work, and significantly shortening the time required to build each square meter of wall. For projects with tight schedules, this advantage is particularly prominent.
Thermal Performance and Energy-Saving Potential
Research conducted in Saudi Arabia indicates that by adding insulation materials or using lightweight aggregates in the block cavities, the thermal resistance of walls can be significantly improved, thereby reducing air conditioning energy consumption.
Huatong Experience: Mature Solutions for Strict Middle Eastern Standards
Huatong Machinery has been deeply engaged in the block making equipment industry for over 20 years and has accumulated rich practical experience in extreme-environment project delivery worldwide. In August 2026, Huatong successfully delivered a QT10-15A fully automatic concrete block making machine to a Middle Eastern client. The equipment is currently in the installation and commissioning phase and will soon be deployed for local infrastructure projects.
In overseas large-scale engineering projects, Huatong's equipment quality has undergone the most rigorous testing. Huatong once won the bid for the Djibouti military port infrastructure project under China Construction Eighth Engineering Division, successfully building 6 high-standard building material production lines. This production line helped the client achieve stable production under extreme high-temperature and high-dust conditions and passed strict project acceptance inspections.
Targeting the standard requirements of various Middle Eastern countries (such as ASTM C129 and the GSO series), Huatong possesses mature mold customization capabilities and can design molds tailored to local regulations, ensuring every brick produced is dimensionally precise and strength-compliant. Huatong not only provides equipment but also delivers full-chain services from mold customization, installation and commissioning to personnel training, ensuring the bricks you produce precisely meet local standards.
If you are evaluating wall material options for Middle Eastern projects, or are concerned about products failing local acceptance inspections, please contact Huatong Machinery. We can customize molds and production line solutions according to local standards, helping your factory gain market competitiveness from the very first day of operation.
