"My wife and I hired Pierce Shallis Landscaping to cleanup our yard, install mulch and regrade the side of our house that was collecting water. Pierce and his team were all friendly and on time. They did an amazing job and were fast and efficient. The outside of our house looks like a model home thanks to Pierce and his team. Now we can sit back, relax and enjoy our beautiful outdoor space. I would highly recommend!!"

"I highly recommend this company. Evan did an excellent job correcting an issue that a previous contractor made when removing trees from my backyard. The price to remove the steep slope and level my backyard was very reasonable. Evan was very responsive, on time, and informed me what needed to be done throughout the entire process. The foundation of my home is no longer in jeopardy, due to this company. They saved me thousands in costly repairs to my basement. I wish there was an option to leave 10 stars, because that?s what this company should receive. I plan on hiring Evan again for more work."

Excavating questions, answered by experts

Excavations take a few days or up to a few weeks. The time it takes to excavate an area depends on the size of the area, the type of soil, the type of excavator, and even the time of year, since winter can make digging up the ground more difficult.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

The best method for digging a trench depends on the scope of the project. For a short, shallow trench (less than 2 feet deep) in light, soft soil, digging by hand may be sufficient. However, digging by hand is labor-intensive, so consider the effort required. A machine trencher is the better option for longer trenches (over 100 feet), deeper ones, or when dealing with difficult soil conditions, such as rocky or hard ground, or obstructions like tree roots. A machine can save significant time and energy in these situations.

Depth is not a qualifying component of evacuation. Any human-made cut, cavity, or depression in the earth’s surface is considered excavation. The hole from excavation can be any size, shape, or depth. Excavation is used to create foundations, reservoirs, drainage ditches, and roads. Long, narrow excavations are called trenches and are often used for underground utilities.

No, a ditch isn’t a trench. A ditch is an open, relatively shallow channel that’s carved out of the ground and used for drainage purposes. In contrast, a trench is a deeper excavation that’s entirely underground. Trenches have many uses, including gas lines, sewage systems, and electrical wiring. Unlike trenches, ditches don’t get filled back in with dirt after they’re dug.
