Heavy Concrete Encasement for Underground Utilities in KSA & GCC
The development of modern infrastructure in the Kingdom of Saudi Arabia and the Gulf region requires underground utility solutions that are durable, long-lasting, and reliable. The expansion of urban areas, industrial zones, airports, and metro networks has made it essential to have high-capacity conduits that can endure the most extreme environmental and mechanical conditions.
Meet the PVC Type EB-35 Conduit – 315 mm (12″) | Heavy Concrete Encasement, which is a premium solution specifically designed for these high-demand applications. Its design consists of rigid uPVC material with EB-35 heavy-duty classification guaranteeing it superior mechanical strength, chemical resistance, and a lifespan of over 30 years. The wide 315 mm diameter opening allows high-density cable installations of all sorts such as electricity, telecommunication, and fiber optic networks which in turn provide a reliable infrastructure backbone for mega public and private projects in Saudi Arabia, UAE, Qatar, Oman, Kuwait, and Bahrain.
Because of its sturdy design, compliance with international standards, and simple installation with concrete encasement, this conduit has become a popular choice in urban highways, metro corridors, industrial facilities, smart cities, airports, and energy projects.
The PVC Type EB-35 Conduit – 315 mm (12″) is a heavy-duty conduit specifically designed for concrete-encased underground applications. The EB-35 classification indicates its superior rigidity and load-bearing capacity, making it suitable for heavy traffic, deep burial, and high-stress areas.
Unlike standard PVC conduits, EB-35 retains its shape under concrete encasement, protecting cables from mechanical stress, soil pressure, and environmental factors. Its smooth internal surface ensures effortless cable pulling and reduces friction, minimizing the risk of cable damage.
The 315 mm diameter allows multiple cables to be installed in a single conduit, optimizing space and reducing the need for future excavation. Its chemical resistance makes it ideal for aggressive soils and high-saline environments prevalent in Gulf countries.
EB-35 conduits are highly reliable for critical infrastructure, including power distribution, telecommunications, industrial installations, metro systems, airports, and smart city projects, making them a preferred choice for long-term infrastructure investments.

Its large diameter allows multiple high-capacity cables in a single conduit, reducing project complexity and cost while ensuring reliability.
To make sure that the whole thing stays stable and the conduit is properly bedded, evaluate the soil type, load conditions, trench depth, and width.
Digging of trenches according to the project specifications with stable sidewalls and safe working conditions will be done.
The compacted sand or granular bedding will be prepared to support the conduit and to avoid point loads.
The EB-35 conduits will be aligned with spacers to keep the separation uniform and to prevent shifting.
Solvent cement or mechanical couplers will be used to make the joints watertight and secure.
Smooth bore allows for easy cable installation with very little friction.
Trenches will be backfilled in layers to ensure support and stability before concrete pouring.
Encasement will share the load equally and will also keep the conduit protected from outside stress.
Warning tape will be placed over the conduit to mark it and to help avoid accidental excavation damage in the future.
