The Science of a Flawless Drain Field

The biggest mistake in septic installation isn't usually the tank itself; it's poor drain field (field line) preparation. If the soil isn't properly evaluated or the trenches are dug at the wrong pitch, the wastewater won't filter correctly, leading to a catastrophic system failure. At Southern Grading LLC, our goal is simple: do the job right the first time.

We don't cut corners on materials, crushed stone, or slope calculations. Because we are experts in professional grading and excavation, we know exactly how to prep the site, lay the pipe, and manage the backfill without compacting the crucial soil in your drain field. When we finish, your system will be fully operational, up to county code, and perfectly graded to blend right back into your yard.
