"There was some confusion with scheduling, but I am completely satisfied with the work after that bump in the road. The tree was removed, and my backyard was cleaned up without any damage to my fence. Price was very reasonable for the work performed."

Customers say: Quality work

"Marty and his team were awesome to work with and very professional. On time and the value they delivered was best in class! Neighbors and strangers that pass by have stopped and asked who did our driveway all the time which is a testimonial of their work quality in its self! The swirl design they put created makes our driveway stand out vs. the boring straight brush look you see from most contractors! I highly recommend Marty and Warrior Concrete!!!!!!!"

Excavating questions, answered by experts

Most residential basements are 8 to 10 feet deep. You can dig deeper depending on building codes, but it does become more difficult. You’ll likely need to install stronger foundation walls and additional supports to handle the increased load. Depending on the water table, you may also need a water management system. Clay soil can support a deeper foundation than sandy soil. A structural engineer will be able to tell you the maximum, feasible depth.

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.

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.

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. 

While you can save some money by digging your own pool, you may end up paying more in construction equipment rental fees in the long run. You could, however, focus your DIY energies on lowering the cost of leveling your lawn for your pool or filling in surrounding landscaping after construction.
