"I couldn't be happier with the concrete work that was done in my backyard. From start to finish, the team was quick, professional, and incredibly efficient. They showed up on time, communicated clearly throughout the process, and completed the project faster than I expected without sacrificing quality. What impressed me most was how they went above and beyond to make sure everything was done right. They paid attention to the details, kept the work area clean, and made sure I was completely satisfied with the final result. The finished concrete looks fantastic and has completely transformed my backyard. I highly recommend this company to anyone looking for reliable, high-quality concrete work. Excellent service, great workmanship, and a team that truly cares about their customers!"

"Absolutely GREAT! I had places to go in December and ordinary bathing and laundry had become extremely time consuming and the problem was worsening. He came out on an already busy day for him and had the whole system (more complicated than some) removed, and the plumbing working again very well in a bit over an hour. Wonderful! I can't add enough superlatives! Left a clean area, besides!"

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.

No, a ditch isn’t a trench. A ditch is an open, relatively shallow channel that’s carved out of the ground and used for drainage purposes. In contrast, a trench is a deeper excavation that’s entirely underground. Trenches have many uses, including gas lines, sewage systems, and electrical wiring. Unlike trenches, ditches don’t get filled back in with dirt after they’re dug.

Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.

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.

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.
