"Totally professional, cordial, & detail oriented. Many thanks to Paul and Ron for doing such a fantastic job! Our large fuel tank had shifted underground, but they handled the unusual situation well. Dig site looks perfect, as though untouched. Too bad we only had 1 fuel tank, because I'd gladly hire them again.Paul even arranged to have our oil burner picked up by someone that may be able to reuse it. Thank you!"

"Iron Earth is the complete deal. They took down an 70 yr old garage that had seen much better days and replaced it with an exciting new garage and RV Port with a storage loft. Dan Faris and his crew did a marvelous job of tackling every step of the process; from planning, permitting, design, teardown, removal of old garage and every facet of the build. Unlike some contractors I've experienced in the past, he listened to our wants and needs. Discussing what could and couldn't be done while providing the details. I knew they were offering us to be partners in the process, not telling us what the project would be like others had. The team was professional and reliable i knew I could trust them in every facet. Iron Earth Construction and Dan Faris will be my go to for future projects, as I know I can rely on them."

"The workers were hard working. Did a great job. The only concern we had was the lack of attention to the workers: no porta potty and no machinery to help carry the heavy concrete. Still waiting for the $250 gift card reward, lol!"

FAQs for excavation projects in Maple Valley, WA

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.
