Septic systems require precise, code-compliant excavation. Tanks need level pads at exact depth. Drain fields need consistent trench depths and proper slope. Get any of it wrong and the system can fail inspection — or fail entirely a year in.
Blake Excavation provides the excavation portion of septic work for homeowners, builders, and licensed septic installers across Southern Oregon. We do not install the septic system itself — that’s a separately licensed trade — but we make sure the hole, the trenches, and the site are exactly right when the installer arrives.
We handle:
Most residential French drains run 18 to 24 inches deep, but foundation drains are often deeper — sometimes 3 to 6 feet. The right depth depends on your soil, water source, and what you're protecting.
A properly installed French drain — with quality filter fabric, the right gravel, and clean pipe — typically lasts 30 to 40 years. Cutting corners on fabric or gravel is what kills them early.
Most residential French drains don't require a permit, but utility trenching and any drainage that discharges to a public right-of-way or wetland often does. We'll let you know up front and help coordinate.
We use clean, washed drain rock — typically 3/4" to 1-1/2" — wrapped in filter fabric to keep silt out. Avoid pea gravel or anything with fines as it will clog the system overtime.
Yes, but downspouts ideally go in their own solid pipe to a separate discharge point. Mixing them with perforated French drain pipe can cause backups.
Whether you need a single trench dug or an entire lot graded and cleared, we bring the right machine and the right approach to every job.
