Why Use PVC for Heavy Utility Duct Banks?
PVC (Polyvinyl Chloride) has been recognized as the most suitable material for underground duct banks due to its incredible performance characteristics:
Corrosion & Chemical Resistance.
Rust, saline soils, moisture, chemical infiltration, and electrochemical decay are all prevented by PVC and these issues are typical in the Gulf region’s coastal and desert areas.
High Impact Strength.
EB-35 PVC demonstrates great resistance to cracking, crushing, or deformation even under the heaviest load stresses, thus making it suitable for locations with heavy traffic or ongoing construction.
Thermal Performance.
PVC stays strong and dependable under high soil temperatures and the variable environmental conditions that are abundant in Saudi Arabia, the UAE, and the GCC region in general.
Lightweight and Easy Handling.
PVC is not only strong but also lightweight compared to materials like ductile iron or steel, resulting in quicker installation and lower labor costs.
Long Service Life.
After a very long time of 50+ years of more than minimal degradation, PVC duct banks continue to perform consistently and cost less in maintenance.
Material Standards & Compliance
EB-35 PVC duct bank pipes meet the standards of recognized international norms, to guarantee their quality, safety, and performance:
ASTM F512 - Rigid PVC Conduit
It specifies the material, dimensions, mechanical properties, and testing criteria for PVC ducts that are intended for heavy utility and concrete encasement systems.
NEMA TC-6 / TC-8
Performance criteria for electrical PVC conduits, such as wall classification (EB-35, EB-20, etc.), are specified by this standard.
UL651 / ETL Certification
It is an optional third-party verification that the product complies with electrical and safety regulations.
By conforming to these standards, the 200 mm EB-35 duct bank guarantees the structural strength, consistent quality, and long-term reliability needed for utility infrastructure in the Gulf region.

Heavy Utility Duct Bank System Explained
A Heavy Utility Duct Bank System consists of several pipes made of PVC, placed in a trench with the help of spacers, and covered with concrete that has reinforcement. This type of structure is effective in load distribution and at the same time, it protects the cables from physical impacts as well as the degradation resulting from the surrounding environment.
Typical Duct Bank Components:
✔ PVC EB‑35 Duct Sections
✔ Bell‑end joints (solvent weld)
✔ Spacers & alignment supports
✔ Reinforcement mesh (as required)
✔ Concrete encasement (engineered mix)
✔ Access chambers/manholes
✔ Cable pulling aids
The moment the duct bank is installed and encased, it becomes a durable utility corridor that is capable of protecting the cables from mechanical loads, soil stress, moisture, and external pressure.
Step‑by‑Step Installation Guide
Step 1: Site Survey & Design
Before installation, perform a detailed site assessment, including soil analysis, load requirements, alignment paths, and depth planning according to engineering standards.
Step 2: Excavate Trench
Dig the trench to specified width and depth. The trench must provide sufficient cover, accommodate multiple ducts, and allow for concrete encasement.
Step 3: Base Bedding Preparation
Spread and compact a sand or gravel base to create a smooth bedding that protects ducts from sharp objects.
Step 4: Lay Ducts
Place 200 mm EB‑35 PVC ducts side‑by‑side with spacers to maintain consistent alignment and spacing per design. Bell‑ends should face the pulling direction.
Step 5: Reinforcement (Optional/Required)
Place steel rebar mesh or cages based on design if additional concrete strength is required.
Step 6: Concrete Pouring
Pour the concrete mixture to encase the ducts fully. Ensure adequate cover (minimum 75–100 mm) on all sides.
Step 7: Cure & Inspect
Allow concrete to cure properly. Inspect alignment, cover, and concrete finish.
Step 8: Install Manholes & Access Points
Position access chambers or handholes as required for cable entry/exit and maintenance.
Step 9: Cable Pulling
Use proper lubricants and cable‑pulling equipment to install power, fiber, or telecom cables.
Following the above steps ensures a structurally sound and long‑lasting duct bank installation.
Design Considerations for the Gulf Region
The Gulf region is full of difficulties that require good solutions in the duct bank design:
High Soil Temperatures
Ducts out of PVC need to be temperature-rated, and the concrete mix should be thermally stable.
Saline & Coastal Soils
Corrosion resistance is very important. PVC has the advantage of being resistant to any moisture and salt, unlike metals which get corroded.
Sand Infiltration
Ducts are protected from sand intrusion through good quality concrete encasement.
Heavy Traffic & Load Zones
Ducts are protected from loads of vehicles and construction by concrete encasement.
Seismic & Vibration Zones
The engineer's design must take into account the soil's dynamics and the need for vibration resistance.
If these factors are tackled, the engineers can then create underground utility systems that are both durable and resistant to the extreme weather conditions in GCC areas.
Accessories & Fittings
For the construction of a heavy utility duct bank system, the following accessories play an important role:
- Bell-end Couplers – pipe joining which is secure
- Elbows & Bends – changes of direction
- Expansion Joints – thermal shifts able to be accommodated
- Cable Pulling Eyelets – cable installation made easier
- Spacers & Supports – alignment maintained
- Manholes & Handholes – access provided
- Marker Tape & Warning Mesh – safety markers
The above-mentioned accessories make the installation process easy and give access for a long time.
Maintenance Practices
Although concrete‑encased PVC duct bank systems are low‑maintenance, follow these best practices:
✔ Inspect access chambers periodically
✔ Monitor water ingress and drainage
✔ Verify concrete integrity around ducts
✔ Perform cable testing regularly
✔ Update duct maps and cable layouts
Routine maintenance enhances system reliability and minimizes unexpected outages.
Performance in Harsh Conditions
PVC EB‑35 duct banks excel in:
Moisture resistance
Chemical corrosion protection
Thermal stability
Mechanical load resistance
Sand and soil ingress prevention
These characteristics make it ideal for GCC climates, including desert interior regions and humid coastal environments
Cost & Lifecycle Benefits
Even though the very first spending on concrete‑encased duct banks might be greater than that of direct burial systems, their life cycle advantages consist of the following:
✅ Prolonged service life
✅ Lesser downtimes
✅ Spending on maintenance reduced
✅ Cable protection up to the mark
✅ Expansion for the future without digging
All these prompters lead to very big savings in the long run.
