PVC Type EB-35 Conduit – 280 mm (11″)

Heavy Concrete Encasement for Underground Utilities in KSA & GC

The new infrastructure initiatives both in Saudi Arabia and the Gulf as a whole demand underground utility systems that will last for a long time and be able to bear heavy loads. As urban expansion continues with new industrial areas, airports, subways and mega-energy projects, reliable conduits are a must to safeguard the mines of electricity, telecommunications, and fiber optics against both environmental and operational pressures.

The PVC Type EB-35 Conduit — Heavy Concrete Encasement 280 mm (11″) is purposely built for such demanding cases. It offers excellent mechanical strength, superb chemical resistance, and lasting stability which together form a guarantee for safe and long-lasting underground infrastructure. Its large size allows it to accommodate various cables, utility lines, and even future growth without the need for expensive re-excavation.

This conduit is specified in government and private projects throughout the whole region, including Saudi Arabia, the United Arab Emirates, Qatar, Oman, Kuwait, and Bahrain because of its meeting the international and regional standards, having a high level of crush resistance, and being compatible with reinforced concrete duct banks.

PVC Type EB-35 Conduit – 280 mm (11″) is a heavy-duty, rigid PVC conduit designed for concrete-encased underground applications. The EB-35 classification indicates enhanced stiffness and crush resistance, making it suitable for high-traffic areas, deep-buried installations, and critical infrastructure corridors.

Unlike standard conduits, EB-35 maintains its shape under concrete pressure, providing a reliable pathway for cables. Its smooth internal surface ensures easy cable pulling, while its chemically resistant composition protects against moisture, salts, and aggressive soil conditions common in Gulf countries.

The 280 mm diameter allows for high-density cable installations, supporting power, telecom, and fiber optic networks in mega projects and smart city applications. EB-35 conduits are engineered to withstand heavy static and dynamic loads, making them ideal for highways, industrial zones, metro rail lines, and other high-stress environments.

  2. Internal bore is smooth which helps in less friction during the installation of the cable
  3. Resistant to chemicals and corrosion since these are aggressive conditions of the Gulf soil
  4. Long-lasting under concrete encasement with a slight deformation
  5. Not conductive and does not catch fire properties
  6. Very high service life more than 30–50 years
  7. Future expansion is supported without re-excavation

Applications

PVC Type EB-35 Conduit – 280 mm is widely used in the Gulf region for:

  • High-voltage power transmission corridors

  • Telecommunication backbone networks

  • Industrial facilities and oil & gas infrastructure

  • Airport utility corridors

  • Metro and railway duct banks

  • Smart city underground networks

  • Urban highway and road duct banks

Its large diameter allows multiple cables to be routed through a single conduit, reducing project complexity and excavation costs. The conduit is ideal for both new installations and expansion of existing utility corridors.

Installation & Usage

1. Site Assessment & Trench Design

To guarantee the stability and right bedding for the EB-35 conduits, it is necessary to assess the soil type, load conditions, and trench dimensions.

2. Excavation

Excavate the trenches with the required project depth and width, while keeping the sidewalls stable.

3. Bedding Preparation

Prepare a sand or granular bedding that has been compacted to hold up the conduits and to keep the point loads from going through.

4. Laying Conduit Sections

Conduits should be aligned and placed using spacers to keep separation and uniform alignment.

5. Jointing

watertight and secure joints are made by using solvent cement or approved mechanical couplers.

6. Cable Pulling

The installation of the cable is made easy by the smooth bore of the EB-35 conduits, thus lessening the friction and reducing the chance of cable damage.

7. Backfilling

Support the area with compact material before the concrete encasement by backfilling the trenches in layers.

8. Concrete Encasement

Pour the concrete gently to ensure that the conduits are completely covered without any displacement.

9. Installing Warning Tape

The warning tape should be placed above the conduit to prevent excavation damage from happening accidentally in the future.
