It's recommended to use a level to ensure that the conduit is perfectly horizontal, and to maintain a consistent spacing of 1/2 inch between multiple conduits. As the conduit is laid, it should be gently pressed into the bedding material to ensure good contact and stability.
After the conduit is in place, it's crucial to cover it properly to protect it from damage and environmental factors. The covering material should be a mixture of sand and gravel, similar to the bedding material, but with a slightly finer texture. This mixture should be spread evenly over the conduit, taking care to avoid any gaps or voids. It's also important to compact the covering material firmly to prevent shifting or erosion.
Finally, it's essential to backfill the trench with soil, taking care to avoid any air pockets or voids. The soil should be compacted firmly to restore the ground to its original state and prevent any future settling or shifting. By following these best practices, you can ensure a safe and reliable conduit installation that will provide years of service.
