Why EB-35 Is Used for Heavy Utility Duct Banks

The EB-35 classification indicates a robust utility duct class that has thicker walls and greater strength than EB-20 systems.

Advantages of EB-35 Classification :

Constructed for heavy load and traffic areas
Perfect for deep installation sites
Improved deformation resistance during concrete pouring
Applicable for big ducts (200 mm–250 mm+)
Recommended for electric power substations, highways, airports, and industrial corridors
Long-term durability and safety assurance for the infrastructure projects in KSA and the GCC with EB-35.

Why PVC Is Ideal for Gulf Infrastructure Projects

PVC has become the preferred material for underground duct banks in the Gulf due to its superior properties:

Corrosion Resistance

PVC does not rust or corrode, even in saline coastal soils, making it ideal for Saudi Arabia, UAE, Oman, and Bahrain.

Thermal Stability

PVC performs well under high soil temperatures commonly found in desert environments.

Mechanical Strength

When encased in concrete, PVC EB-35 ducts withstand heavy loads from traffic, construction equipment, and soil pressure.

Lightweight & Easy Handling

Despite its strength, PVC is lighter than steel or concrete conduits, reducing installation time and cost.

Long Service Life

PVC duct banks offer 50+ years of service life with minimal maintenance.

Material Standards & Compliance

The 250 mm EB-35 PVC Duct Bank Pipe is manufactured in compliance with international standards to ensure safety and performance:

ASTM F512 – Rigid PVC conduit for utility and duct bank systems
NEMA TC-6 & TC-8 – Electrical PVC conduit classification
UL 651 / ETL (optional) – Electrical safety certification

These standards make the product suitable for government, utility, and EPC projects across the GCC.

How Heavy Utility Duct Bank Systems Work

In a heavy utility duct bank, a number of ducts are placed in a trench, lined with spacers, reinforced (if needed), and covered with concrete. The installation is done in such a way as to accomplish the following:

- Distributing the external load

- Avoiding any distortion of the duct

- Keeping the cables safe from water, pests, or accidents

- Marking out neat passages for the utilities

Usually, the EB-35 PVC duct of 250 mm diameter is the most common choice for the trunk duct in such systems.
