"Meridian Roofing Solutions contacted a few excavating companies for some dirt work we needed on a roofing project. Apex Excavation was the first to respond and provided an accurate quote. I was most impressed by how they communicated to us and understood the project. I would definitely work with them again and recommend them for any dirt work needed."

Excavating questions, answered by experts

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.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

The average cost of excavation is approximately $3,200, with typical projects ranging from $500 to $15,000. Depending on the contractor, you may be charged between $50 and $200 per cubic yard or an hourly rate of $40 to $180 for an excavation specialist. The total cost is influenced by several factors, including the project size, the amount of soil to be removed, and the soil's condition. Hard soil, tree roots, or excessive rocks and clay can increase the price, potentially adding $200 to $1,200 to the final bill. Other factors that can drive up costs include the presence of nearby structures that complicate the work or tight spaces that require manual excavation instead of heavy machinery.

Most professional excavation teams will charge between $8 and $15 per cubic yard. Calculate the cost by finding the volume of your pool—width x length x depth—and dividing it by 27. Then, multiply the price by the cubic yards from your equation. Budget for complications like a rocky lawn, hard-to-access pool area, or high local labor prices.

If you have a broken sprinkler pipe underground, there will be some signs you can easily spot to locate it and take action. These include leaks, water spouts, flooding, consistently damp areas on your lawn, low water pressure, and grass around the sprinkler head that’s taller and darker than anywhere else in the yard. 

If there are no obvious signs of a broken pipe, you can use tools such as water leak mics, leak noise loggers, audio devices that record leaks, and acoustic testing links. 

Broken pipes can lead to uneven watering, plant damage, and higher utility bills. The longer you wait to fix them the more the repair cost may be.
