Before Building a Patio

Verify that your new outdoor living space will not permanently block access.

What is about to happen?

You are building a permanent outdoor living space using pavers, flagstone, or stamped concrete.

What hidden system could be affected?

Septic tanks and main sewer lines. Patios are often built right off the back door, exactly where these lines exit the house.

What clues or records may help?

Check the property's utility and septic as-built diagrams. Look for brass cleanout covers in existing walkways.

What does the visible surface not guarantee?

The perfect flat spot for a patio is often the same flat spot the original builders used to bury the septic tank.

What becomes expensive if wrong?

Tearing up a newly installed $15,000 stamped concrete patio to pump a septic tank is a catastrophic waste of money.

When should local confirmation happen?

Before signing the contract with the hardscaper. Verify the exact footprint against all known underground systems.

Need to verify?
