Pacific U-drains are designed to be installed with ease, requiring very little excavation to place and a minimal amount of backfill. Pacific box culverts are supplied with lifting anchors to make lifting and placing both easy and precise.
- Soil excavation followed by base preparation; levelled to ensure easy alignment of U-drains and prevent settling of soil. In the case where the water table is located in the trench zone, dewatering methods must be employed to remove the water.
- Backfill of soil should be granular and be compacted layer by layer beginning form the side walls to top of the box sections to attain the required minimum density.
- Bends can be designed during manufacturing to allow for curved pathing during installation.
- Male/Female joints are provided for Arto Box Culverts to slide and lock into place. Furthermore erosion control seals, rubber rings, exterior joint wraps, expanding water stop seals or grouts can be used to make the joints watertight as required.
- Based on the topography of the land we can manufacture U-drains of different depths to maintain top level or have them step down by using drains of a constant depth.
