"Had a retaining wall done? Eric was great in keeping me informed of all steps up to the very end and was easy to work with. His team did an outstanding job and the wall looks great. It is nice to have a company that shows pride in its work and cares about the customer. I highly recommend them."

"I hired Ben to recreate a retaining wall on my property. I gave home some guidance on how it should look, provided pictures and examples, however as he started to lay it out I had some modifications and feedback. He took all feedback and used his skills and experience to make it look natural but also function as a retaining wall. Beautiful and functional work at the end of the day and very reasonable pricing."

"Working with Mid-Valley Excavation was an excellent experience. They took the time to come out and give a thorough bid inspection. They spent a good amount of time talking to us, listening to our wishes and needs and discussing project scope and requirements. They delivered a bid quickly and they were very responsive to follow-up questions and concerns. Their work is great, the end result was above and beyond my expectations. They were quick, efficient, and work with an attention to detail. It was a pleasure working with them. I would hire them again for future projects."

"They were a couple weeks out when we hired them, we went in a hurry so it worked. They were to start on a Monday and pour the following Friday. When they arrived they said we have concrete coming later today. The crew got it dug II, removing the stump, adding rebar, gravel and cement was down by 3:00 same day. We were happy. They came back today to strip the forms do a final cleanup. We are having them look at another project too. 5 stars."

Excavating FAQs, answered by experts

There is no standard depth for burying a septic tank; they are typically buried anywhere from 4 inches to 4 feet underground. The final depth depends on several factors, including the depth of your main sewer line, the height of the bedrock, soil type, local regulations, and the property's landscape. If you plan to grow grass or plants over the tank, a depth of at least 4 to 6 inches is recommended. Deeper tanks can be more difficult to locate, but a septic professional can help find it for you.

Concrete blocks are the cheapest way to base a shed. However, the space in between allows critters to go under, burrow, and even damage your shed’s frame. For a more pest-proof option, consider building a shed base with gravel or paver stones. Both options are fairly affordable and easy enough for a DIY project. For gravel, you can build a wooden frame to contain the loose material.

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.

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.

Consultation with the local government helps identify necessary permits, avoid project delays or legal issues, and protect project integrity.
