Specifications, Uses, Installation & Gulf Region Guide
Why Choose PVC for Duct Bank Systems?
PVC is counted among the materials that are the most used ones for the underground duct systems because of its properties like strength and long life and cost effectiveness. There are several reasons for which the use of PVC is favored:
- Corrosion & Chemical Resistance: PVC withstands the onslaught of very aggressive Gulf soils and saline atmospheres and moisture infiltration that can work on metallic alternatives and eventually degrade them.
- Lightweight & Easy Handling: PVC ducts are lighter than concrete or steel conduits, consequently, the costs for labor and time for installation are reduced.
- Impact Resistance: High‑modulus PVC conducts mechanical stress without fracturing.
- Thermal Stability: PVC can withstand the high ambient soil temperatures that are often encountered in Gulf region.
- Longevity: PVC duct banks can last for many years, with very little maintenance, which makes them suitable for infrastructure planning that is very long term.
Material Standards & Compliance
To ensure consistent quality, performance, and safety, 160 mm EB‑20 PVC duct banks must comply with international and regional standards relevant to underground utilities:
- ASTM F512 – Standard Specification for Rigid PVC Conduit Suitable for Direct Burial and Concrete Encased Duct Banks.
- NEMA TC‑6 / TC‑8 – Defines electrical plastic conduit performance, wall thickness classes, and mechanical properties.
- UL651 / ETL Listing – Where applicable, additional certification demonstrates compliance with safety and material standards.
Adhering to these standards ensures that the duct bank will withstand anticipated loads, environmental conditions, and installation stresses in demanding infrastructure projects across Saudi Arabia and the Gulf.

How EB‑20 Duct Works in a Concrete Encased System
A concrete encased duct bank refers to a structured assembly of ducts surrounded by reinforced concrete. The concrete provides load distribution and protection layers, while the PVC ducts house cables safely.
Key elements include:
Trenched excavation to design depth
Bedding layer (sand/stone)
Spaced PVC ducts (kept aligned by spacers)
Steel reinforcement mesh (optional/required)
Concrete encasement poured to specification
The result is a durable duct bank that protects utility lines from everyday stressors, construction impacts, and environmental challenges.
Step‑by‑Step Installation Guide
Step 1: Site Assessment
Evaluate the site thoroughly to assess soil type, load requirements, existing utilities, and project depth standards.
Step 2: Trench Excavation
Dig the trench to the specified depth and leave a stable base. The trench should be wide enough for multiple ducts.
Step 3: Base Preparation
Put a layer of compacted sand or gravel as a duct protection against sharp objects and to provide uniform support.
Step 4: Laying Ducts
Install 160 mm EB‑20 PVC ducts with spacers for uniform spacing. Make sure the bell‑ends are in the right pulling direction.
Step 5: Reinforcement
Put steel reinforcement as per structural design to increase the strength of concrete.
Step 6: Concrete Pouring
Pour concrete cover to the specified minimum for all ducts by the design standards.
Step 7: Cure & Inspect
Allow concrete to cure, then inspect for alignment, level, and finish surface.
Step 8: Cable Pulling
After curing, pull cables using lubricant and proper pulling equipment for a smooth installation.
All steps must be carried out in accordance with the engineering standards and GCC infrastructure codes for safety and performance.
Design Considerations for the Gulf Region
Working under the conditions of the Gulf climate demands special care to:
✔ Very High Soil Temperatures — the PVC used should be able to withstand the high underground temperature.
✔ Salt and Coastal Soils — the resistance to corrosion should be a must.
✔ Heavy Vehicles & Construction Loads — the ducts will be protected by the concrete encasement.
✔ Sand Ingress — Concrete will block any access for sand to come in.
These factors render 160 mm EB-20 PVC duct banks as perfect for being extremely durable in severe places and for a long time.
