House on one side, patio on the other. ✔️ HD Chambers gave us a 40% smaller field to fit the space, with stone between them and fabric over top. ➡️ Best of both worlds. 🤘🏼🔥

Proper installation matters. We never drive over a chamber system—even during backfill.

Out of sight shouldn’t mean out of mind.
✔️ Installed a riser for easy access & maintenance
✔️ Added a leach field vent to improve airflow
✔️ Repaired crossover tubes to keep the system flowing right
✔️ Lawn restored like we were never there.

The right repair now can save you from replacing an entire leach field later.
