Property Work, Built to Last
Drainage that washes out every spring. A driveway you re-gravel every year. A greenhouse or garden you've always wanted. Whatever your land needs, GSS builds it on sound principles — designed and built by the person who understands why it has to hold up.
It All Starts with the Soil
Drainage, driveways, gardens, lawns — every one of them lives or dies on what's underneath. That's why soil comes first in how GSS works: understand how your ground holds water, bears load, and grows things, then build accordingly.
Todd Guerdat, PhD, spent his career on exactly this — soil and water science, five years as a USDA NRCS civil engineer, and hands-on building. The result is property work that's matched to your site instead of forced onto it.
