"Central Wisconsin Excavating (CWE) did a fantastic job on our project. They built a solid, well-prepared foundation for our 80,000-bushel grain bin and graded our driveways perfectly to ensure water drains away from our buildings. Their attention to detail, quality of work, and professionalism really stood out. The site was left clean and properly finished, and everything was done right the first time. We’re extremely happy with the results and would highly recommend CWE to anyone needing excavation or site work done right."

"I hired AP Excavating to expand our parking area with a stone pad. Additionally they excavated, prepped and dialed in a pad for our hot tub and sauna. They also installed a new drainage solution. Through the entire process Gus was super helpful in providing updates and communicating options and recommendations for various details. I’d highly recommend this contractor."

"I hired Mike for general property work, including grading, splitting a berm for an open area on my property with his loader, as well as tree planting and landscaping work. He was a pro, very careful with his equipment on my property, and did exactly what I needed done, very efficiently. I will definitely hire him again the next time I need any work done at my home and business locations. He is always courteous, polite and professional."

"Great team to work with. The job was done a day early and completed quickly. Three window wells replaced and grading done. Very nicely executed, the job site cleaned up, and all at a reasonable cost. Definitely recommend On Board Landscaping."

Excavating FAQs, answered by experts

Depending on the severity of the freeze and the method used, thawing frozen underground pipes can take anywhere from 30 minutes to several hours. Applying heat directly to the pipe using heat tape, infrared lamps, or hot water jetting can speed up the process. However, patience and careful monitoring are key to avoiding pipe damage.

The best way to protect tree roots is to avoid the roots entirely by excavating outside the root radius of the tree. For nearby projects, it’s a good idea to construct a temporary retaining wall. But that’s not always possible, depending on the project and the root system. In these cases, consider using alternative equipment like an auger to tunnel under the ground.

Remember, tree roots can damage nearby cement foundations as they grow. If a tree is close enough to interfere with large excavations, it may be better to remove the tree than risk future problems.

Water lines are buried at various depths, depending on the type of line. For example, most sprinkler lines are buried between four and 12 inches underground. On the other hand, water mains usually sit between one and 3 feet below ground. However, they can go even deeper in cold climates to prevent freezing.

Downspouts should be buried at least 5 to 10 feet away from your foundation. This can vary depending on your local building codes, soil type, and property slope. The main goal is to ensure water is directed away from your foundation.

The rules and regulations regarding groundwater use vary between states. To find out if you can dig a well on your property, you’ll have to consult these regulations, address any compliance requirements, and get the appropriate permits. It’s also important to check that your intended location has the right geology and water table to support a well.
