"Geoff and his team were a lifeline as no one seemed to know how to find the leak that was causing a major water leak in my yard. They located the leak and repaired the water line within 24 hours of contacting them. They were on time, extremely fair on the quote and communicated with me throughout the process. They did a top notch job and most importantly gave me peace of mind. I will be calling on them again with any major repairs and highly recommended Sound Tradesmen LLC."

Excavating FAQs, 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.

Excavations take a few days or up to a few weeks. The time it takes to excavate an area depends on the size of the area, the type of soil, the type of excavator, and even the time of year, since winter can make digging up the ground more difficult.

Consultation with the local government helps identify necessary permits, avoid project delays or legal issues, and protect project integrity.

To locate an underground downspout, you should start by identifying where the above ground gutter drains. Look for an entry point, such as a pipe or elbow leading into the ground. Follow the surface path for signs like depressions, landscaping disruptions, or wet areas after rain. You can use a metal detector or plumber’s snake to trace the pipe underground. For deeper pipes, a professional locator tool or camera inspection may be necessary. Visual markers or utility maps can also guide the search.

Because decomposed granite is a durable material, a crushed rock or gravel base is optional as long as the DG is properly installed and compacted. However, installing a base is a good idea because it will ensure proper drainage and stability and act as a weed suppressant (although you may still occasionally have to pull weeds). Installing an adequate base can also increase the durability of driveways and walkways. If you forego the paver base or gravel underneath, line the area with landscaping fabric to avoid weeds.
