"Eric was able to competitively quote and execute a significant improvement to our property in Larkspur by excavating a new parking area as well as installing a stunning retaining wall to mitigate erosion that would have caused the loss of mature pine trees. He also relocated all the dirt to other areas of our property to encourage proper flow of rain and snow melt away from our home. Every step of the project was executed perfectly, on time, with excellent communication and its completion not only served the purpose we needed but it has greatly improved the aesthetic and value of our property. I don't remember the last time we've worked with someone on a home project that has been this impressive."

"David, excavated old septic tank, replaced with new tank, hooked up tank to house, filled in and covered the new tank. Leveled the land, raked the area affected and applied grass seed. Clean up was great! Was always available to answer questions. We would hire him again."

"My barns used to flood badly whenever it rained, but since Eco contractings re-grading, there is no more flooding! I am very happy with their work and would recommend them to anyone in need of grading work. Michael was professional and returned my call immediately and addressed any concerns I had about the project. The price was very reasonable for the work they did and I could not be happier."

"These guys repaired my wooden fence from the January windstorm. Dug out and replaced 7 posts and reattached 10 - 8' sections. They showed up and worked through a January snow to get it done fast. Good price too."

Excavating questions, answered by experts

Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.

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.

A walk-behind trencher can cut through roots as long as they’re not too thick, making a project much easier than digging with a shovel and other hand tools. Assess your terrain and the number of trees in the surrounding area to determine if a walk-behind trencher will ease the job. Digging a trench by hand is much more time-consuming and labor-intensive. 

It can take several weeks for the ground to settle after removing a tree, and the soil under larger, more mature trees can take months. The deeper the tree has been ground under the soil, the longer it will take to settle. However, this extra depth can help you plant new landscaping sooner because you’ll have more space for fresh soil.

Water lines are buried at various depths, depending on the type of line. For example, most sprinkler lines are buried between four and 12 inches underground. On the other hand, water mains usually sit between one and 3 feet below ground. However, they can go even deeper in cold climates to prevent freezing.
