"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

While general contractors sometimes handle demolition, you can also look specifically for local demolition contractors. Demolition experts need to understand structural integrity, the equipment needed for safe demolition, and the permits required for demolition.

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.

Yes, trenchers can go through gravel. Gravel is made up of smaller, softer rocks that certain trenchers are able to cut through. Just be sure to use a rock wheel trencher or chain trencher, both of which are made to cut through rocky landscapes and gravel pathways without dulling the teeth or chain.

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

A trench that is less than 5 feet deep often doesn't require a protective system. Most residential trenches will not go this deep (the typical residential drainage trench is just 18 inches deep). In the event that an excavator needs to dig more than 5 feet beneath the surface, a protective system is required unless the excavation is in entirely stable rock.
