P&C Duct Type DB-120 Heavy Wall- 20'

Prime Conduit’s P&C Duct Type DB is a premium nonmetallic conduit system designed for power and communication installations. Manufactured from Prime Conduit’s exclusive high-modulus PVC compound, it is engineered for both direct burial and concrete-encased applications. With a 90°C cable rating, it offers superior protection and durability, making it an ideal solution for a range of underground electrical and telecommunications projects.

Trenching Guidelines

The trench for installation should be free of stones and soft spots to ensure the stability of the conduit. For optimal performance, the sides of the conduit should be firmly tamped, though tamping on top of the conduit is not recommended. In rocky soil conditions, a selected backfill is essential before laying the conduit to provide a stable foundation. A backfill of at least 6 inches of non-tamped material over the conduit is recommended to avoid damage and increase longevity.

Backfill Recommendations

In rocky terrain, the trench bottom should be prepared with selected backfill materials to maintain a smooth and even base for conduit placement. After conduit installation, an additional 6 inches of selected backfill should be placed over the conduit. Final backfill and tamping may be used to complete the grade after placement, ensuring a strong, secure installation.

Direct Burial Installation

The installation method for direct burial can vary based on soil conditions, load factors, and engineering preferences. For optimal results, many professionals lay one tier of conduit at a time, followed by backfilling, and continue layering as needed. For areas with minimal load requirements, a duct-to-duct formation using the heavier wall Type DB-120 has proven to be an effective and reliable solution for long-term performance.

Whether you're installing power or communication systems, Prime Conduit’s Type DB offers the strength, flexibility, and protection needed to handle tough environments and ensure reliable performance in both direct burial and encased installations.
