Key Features & Performance Advantages

✔ High Mechanical Strength

The corrugated outer layer acts as a buffer and easily withstands heavy impacts along with traffic loads and soil pressure — it is the ideal solution for excessive trafficking, road crossings, and deep installations.

✔ Smooth Inner Surface

There is less friction from the cable, and there is no damage at all during pulling or blowing operations.

✔ Lightweight & Easy Handling

This kind of installation is still much easier when compared to other methods of piping, including concreting, using PVC, or steel pipes.

✔ Corrosion and Chemical Resistance

The product is suitable for all types of soil in the GCC region, including saline, sandy, and moist environments.

✔ Flexibility

It is possible to bend the pipeline along the curves without the need for making multiple joints.

✔ Very Long Service Life

The product is made to last for more than 50 years underground.

✔ High Thermal Stability

The material is suitable for the very high temperatures prevailing in the desert regions of the Middle East.

✔ Cost-Effective Solution

Low transportation cost, quick installation, reduced maintenance, and fewer failures are the main advantages of this solution.

Installation Guide

A reliable installation ensures long-term performance. The general installation procedure includes:

Step 1: Trench Preparation

  • Dig trench to the required depth.

  • Remove sharp stones and debris.

  • Prepare the bedding layer with sand or soft soil.

Step 2: Duct Placement

  • Lay the ducts in straight alignment.

  • For curves, flex the ducts naturally without forcing.

Step 3: Joining the Ducts

  • Use compatible couplers or rubber-seal connectors.

  • Ensure airtight and watertight sealing.

Step 4: Cable Pulling

  • Use lubricants suitable for HDPE ducts.

  • Follow load & bend radius guidelines.

  • For fiber optic cable, use blowing method where required.

Step 5: Backfilling

  • Initial layer of soft soil or sand

  • Second layer of compacted soil

  • Final layer as per project specification
