Site Evaluation
Soil profile, slope, setbacks, and water-table check on your actual property.
A new system is one of the biggest things you’ll put in the ground. We design it for your soil, permit it through your county, and install it cleanly, all under one TCEQ license and one point of contact.
Cornerstone installs complete residential and light-commercial septic systems across Austin and the Texas Hill Country. Whether you’re putting a system on raw land, a new custom build, or replacing one that has reached the end of its life, the work goes through the same licensed hands from start to finish.
No two sites are the same. The soil profile, the slope, the setbacks from wells and property lines, and how many bedrooms the home has all change what your system needs to be. We start with a real site evaluation instead of guessing, then design a system your land can actually support and your county will actually approve.
Good soil and enough land usually allow a conventional gravity system. Tight clay, rock, or small lots often need an aerobic system. Your soil test decides, and we explain the trade-offs before you commit.

We meet the county inspector, get the final sign-off, and hand you the paperwork.
Tell us about your property and we’ll set up the site evaluation. From there you get a firm scope and a firm number.
