Why EB-35 Is Used for Heavy Utility Duct Banks

The EB-35 wall class offers superior structural strength as compared to EB-20 or regular PVC conduits.

Benefits of EB-35 PVC Ducts:

  • Deep burial and heavy traffic area applications
  • Very high mechanical strength within concrete encasement
  • Greater resistance to both deformation and crushing
  • Applicability for large-sized ducts (315 mm and above)
  • Acceptable for projects involving industrial, transport, and utility infrastructure

In the case of major infrastructure projects in Saudi Arabia, UAE, Qatar, Bahrain, Oman, and Kuwait, EB-35 guarantees long-term reliability, durability, and safety.

Advantages of PVC in Gulf Region Infrastructure

PVC is the material of choice for duct banks in Gulf infrastructure due to its combination of durability, cost-efficiency, and environmental resistance.

Key Benefits:

  • Corrosion & chemical resistance: Ideal for saline soils and coastal areas

  • Thermal stability: Performs reliably under high soil temperatures

  • Mechanical strength: Maintains integrity under heavy loads and concrete encasement

  • Lightweight: Easier handling and faster installation compared to steel or ductile iron

  • Long service life: Minimal maintenance for 50+ years

Material Standards & Compliance

The 315 mm EB-35 PVC Duct Bank Pipe complies with international standards:

  • ASTM F512 – Rigid PVC conduit specifications

  • NEMA TC-6 / TC-8 – Heavy-duty electrical conduit standards

  • UL 651 / ETL (optional) – Electrical safety certifications

These standards ensure the product meets quality, mechanical strength, and safety requirements for GCC projects.

How Heavy Utility Duct Bank Systems Work

A heavy utility duct bank includes various ducts positioned in a trench, supported with spacers, reinforced (if necessary), and surrounded by concrete.

Key Functions:

  • Distributes external loads uniformly
  • Shields cables from physical damage, water and soil pressure
  • Offers a neat and reachable utility path

The 315 mm EB-35 duct is commonly used as the primary trunk conduit in these setups.
