"Professional-Meticulous-Skilled Hiring Willow Creek Land Design was the best decision I could have made! There were many companies to choose from but Willow Creek stood above the rest. It began with an immediate response to my inquiry and continued throughout the project. Communication and prompt response made the process easy. Each interaction was professional and pleasant. I asked for several project bids and needed several drawings to submit with permits, each request was hand carried within a day or 2. Willow Creek was the best choice for many reasons; their excellent management was carried through in the quality of their team. Johnny and his crew treated the jobsite, my property, like it was their own. They put plywood down to protect the area where they would be walking. Meticulously attending to the smallest detail, they worked like a well,-oiled machine, creating a wall I wanted them to sign when it was done! I am a designer myself and I am very particular, I see details many people could care less about. This crew is just like me! I was happy to see that one of Johnny's go-to tools was his level! I could not be happier and if their was a rating higher than 5 I would have given it. I have much more work that needs to be done and I'm feeling great about having the best team to help me accomplish it all! I highly recommend Willow Creek Land Design. Grateful in Kingston, Doreen P."

Excavating FAQs, answered by experts

A perc test can take anywhere from one to eight hours to complete. The total time depends on factors like the amount of excavation required, the depth and width of the holes, and whether multiple test holes are needed. For a single hole, the process of filling it with water and monitoring the drainage rate usually takes less than an hour. Professionals can often complete the entire test in a single day. While it's possible to get results the same day, some companies may take a few days to provide the official report.

Excavation is priced in cubic yards, so you’ll need to find the volume of the area in order to calculate costs. Multiply the length, width, and proposed depth of your excavation site, then convert it into yards to get the volume. Multiply this figure by the price per cubic yard.

Most homeowners can measure by hand to get a rough estimate, even if it’s tedious. You may want to pull out a tape measure or use a string to help mark the area.

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.

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.

Trenches are typically 12 to 24 inches deep and 8 inches wide. However, the required depth depends on the specific project and local ordinances. For example, a French drain may need to be 18 inches deep, while a water pipe might require a depth of 24 inches and a drainage pipe 36 inches. Your city or county may have specific regulations, so it's wise to consult with an excavation professional to determine the correct depth for your project.
