Excavating questions, answered by experts

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.

The rules for trenching and excavation include setting up and following safety protocols, learning how to use tools and machines properly, and ensuring there is a safe exit for all workers. Keep heavy equipment and materials away from the edge of the hole or trench. Call the 811 dig line before starting any excavation or trenching project to ensure you don’t hit any electrical or gas lines.

Tree experts don’t advise against digging through tree roots, but instead encourage caution and consultation with a local arborist to make sure you don’t damage the tree’s structure or interrupt its water or nutrient intake. An arborist can recommend specific practices when digging and help prune the roots or dig a trench for utilities with a tool that can remove soil without touching the tree’s roots.

Maintain open communication and address issues as they arise, ensuring contract terms cover potential delays.

Yes, you can install a trench drain if you already have concrete in your yard or garden. While it can complicate some aspects of the job and slightly run up the cost, it is doable. Residential trench drains can be easily retrofitted to outdoor areas with concrete without having to remove excessive amounts of your patio, pool area, or decorative walkways.
