"I have to give a HUGE shout out to Mahan Septic Systems and Dirt Work from Hot Springs, AR. We had a stopped up toilet and needed some assistance. We found them on Angi and they contacted us immediately. We made arrangements and they came the next day and found the issue and solved it. They even came back the following day and fixed the toilet lid (which wasn't even on the fix list!). I would highly recommend giving them a call the next time you need any septic and plumbing work. Call (501) 617-7689. Thank you Mahan!"

"This company is fantastic! Highly Recommend!! Joseph (the owner) is very easy to work with, first of all! I hired his company earlier this year to redo my entire back yard and turn it into and outdoor paradise! He was able to create an impressive, detailed 3D model on the computer of exactly what I wanted and he and his team executed it perfectly! He was able to work in conjunction with a contractor I hired to put an in ground pool in and it was seamless! Rain was an issue during our project but thatâ  s how it goes sometimes.. Greennecks was able to come in and take care of the entirety of the project in an orderly, timely manner. Their work is very neat, his workers are highly professional. I will be using them again in the future!"

Excavating questions, answered by experts

The physical constraints of hand-drilling a well limit the depth you can achieve. Manually digging with picks and shovels may only lead to shallow wells of up to 60 feet in depth. To reach greater depths, you need more specialized equipment. The diameter of your well and the tools you’re using will determine how far down you can dig.

It takes one hour to dig a 10-foot trench by hand. Use a trenching shovel with a sharp tip and a long head. Plan for more time if your soil is heavy or rocky. Consider renting a trencher if you’re digging a long or deep trench or if you have challenging soil or terrain. 

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.

Chipmunks dig their burrows about three feet deep and up to 30 feet long. The entrances can be two inches wide or more. Chipmunks are fiercely protective of their burrows and use them to protect the nuts and seeds they gather for the long winters.

Call 811 to locate and mark the gas lines at least three days before digging. In many areas, you can dig within 18 inches of the lines, though in some locations, the distance may be further. Check local regulations, as you may need a utility company representative onsite when digging. Document your calls to 811 and precautions taken to avoid gas lines. A homeowner can be held liable for hitting a gas line in some cases, but contacting the proper authorities and following all guidelines can offer protection.
