Excavating questions, answered by experts

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. 

Yes, professional installations include trenching or borehole drilling required for ground loops.

Errors in site preparation can lead to structural failures or appear costly midway. Professionals ensure detailed, reliable home base development layouts.

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.
