"AP Excavating installed a drinking post for our horses and replaced a water hydrant. Wonderful father and sons family business - great to work with them and their crew. I was impressed with the quality of work and their commitment to making sure they exceeded our expectations. I will be using them for our next projects: entry gate, trenching work and landscaping driveway island. Thank you AP Excavating!"

"Rich Che and the CNS Empire Landscape crew did fabulous improvements on our family home in Wheat Ridge. They corrected drainage on three sides of an addition so water flows away from the house instead of into the crawlspace; replaced 30 feet of exit pipe from the perimeter drain around the foundation of the addition; installed new sod; and removed weeds from landscaped rock areas in the front yard. The improvements look great. Shortly afterwards, I engaged an inspector to check the foundation. The inspector said he visits about 400 houses each year, and this drainage remediation is among the best he’s seen."

"Tanner and his crew were professional and thorough. They took care to minimize the impact of having a small loader in my yard, and rehung the gate to the back yard better than it was before. Well done and would recommend."

Excavating questions, answered by experts

No, you typically cannot use metal detectors to find your sewer line. Most sewer lines are made of non-metallic materials such as PVC, clay, or cast iron, which are not detectable by standard metal detectors. Metal detectors are designed to locate metallic objects, so they won't be effective for identifying the path of a non-metallic sewer line. To locate your sewer line accurately, it's best to use other methods.

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.

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.

Hard soil could be a sign of overly dry dirt, either from poor drainage or drought. It's important to test the nutrient levels, density, and drainage capacity of your soil to see if it's absorbing water properly. Begin by adding a light layer of water and observing how long the soil retains moisture. If you experience a good deal of runoff, you may need to aerate your lawn, apply a wetting agent, or hire a professional for a closer look.

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.
