Scope & limitations
GPR does not certify septic systems for health departments or prove potable water quality. Engagements are scoped in writing. Clay, high moisture, or metallic clutter can narrow confidence—see soil moisture and GPR depth for why.
Septic tanks, drainfields, and unknown laterals. We often image tank edges and suspect trenching when contrast is favorable. Your health inspector or designer may still require other methods for compliance—we coordinate to the purchase order, not to an implied warranty.
Private well lines. Buried HDPE or PVC routes can be elusive depending on depth and fill history. When rural or exurban work points match our well line locating service description, we will say so up front; otherwise we may recommend a different scope.
What to have ready before we arrive
- A marked work area (pool dig, addition footer, trench path).
- Any as-builts or prior sketches—even wrong ones narrow questions.
- Clear access across the grid we need to walk; pets secured if applicable.
