"Totally Excellent! Jon and the Crew at ERE flattened out about a 1 acre square of my property (future building site) Perfectly! And it was a gnarly pit to start with full of boulders and old items like water heaters and car fenders as it was evidently a dump site for the neighborhood before I got here. Finished the project quickly and to my complete satisfaction, I recommend ERE to Everyone for your next Excavation project, big or small Jon can handle em All!"

"Colton did a great job with welding up my dump trailer. Overtime it developed some issues and without hesitation, he came and picked up my dump trailer for me and immediately got to work and got it back to need fixed as I requested within about a day and a half."

"I honestly cannot say enough good things about ERE! We were having some drainage issues in our backyard, and were worried about the integrity of our foundation. Jon contacted me within a day of my search and set up a consultation a few days later. He was super knowledgeable and understood what I wanted done, even when I couldnâ t exactly describe it. Jon was very thorough and kept me updated on everything he was going to be doing, and gave me several options when it came to budgeting and services. He and his team even went above and beyond by repairing the sprinkler lines that the previous owner had damage, at no extra cost. Our backyard now looks 100x better than before and we no longer have to worry about water draining towards our house & foundation. I will absolutely recommend ERE to everyone I know & will likely use them in the future for any of our landscaping needs!"

FAQs for excavation projects in Spearfish, SD

Depth depends on the type of installation and the regulations in your area. Water supply lines typically require 24 inches, while drainage pipes are often installed 36 inches below grade. For most general projects, a depth of 12 to 24 inches and a width of about eight inches is sufficient. Sticking to these specs keeps your utilities safe, code-compliant, and easier to maintain later.

When you need to run utilities underground, you’ve got two main options: boring or trenching. Boring employs directional drilling to install utilities without exposing a continuous channel, while trenching requires excavating an open channel to place utilities securely. Directional drilling preserves landscape integrity, whereas trenching provides direct access for installation, albeit with greater surface disruption. This clear comparison helps you select the method best suited to your project.

Plan on 12 hours to dig 100 linear feet when the soil is cooperative and you can work continuously. This timeframe applies when work is performed consistently and methodically. Factors such as rocky soil, tree roots, obstructions, and frozen ground increase the overall duration, demanding extra planning and effort. Comprehensive operational planning ensures that every challenge is managed efficiently and the project is completed on schedule.

If you want your yard to look untouched, laying fresh sod over the trench is the quickest fix. New sod needs 30 to 45 days to root and blend with the rest of your lawn. A local sod pro can provide you with a firm timeline and tips to ensure the grass takes hold and maintains your curb appeal.
