Excavating questions, answered by experts

This depends on your location. Sewer lines can be buried anywhere from 18 inches to 8 feet deep. People in colder climates will have deeper sewer lines than people in warmer climates due to the dangers of the frost line and freezing pipes. Permits are required for all aspects of septic system installation, so the city should have the building plans for your system, which will tell you how deep your lines are.

Professional installers often include a deep layer of crushed gravel under permeable pavers to allow more runoff to soak through into the soil below. Many installations will include multiple layers of gravel, with coarser aggregate at the base and finer aggregate that sits on top of that bottom layer. Above the gravel, you’ll often find coarse sand that helps reduce paver shifting over time. Some permeable paver designs include a water collection system set into the gravel layer to route runoff to a safe area for disposal.

A mini excavator can dig between 5 and 11 feet deep, depending on the type and size of the mini excavator. Mini hydraulic excavators are more powerful and can reach deeper into the earth, but electric models have a more limited range. Mini excavators over two tons in size are also more powerful and able to dig as deep as 11 feet.

If you’re planning to dig on your property, you’ll need to check for underground utility lines. Call the national call-before-you-dig 811 number. Once connected to an operator, you can schedule a site visit to mark underground lines. This way, you won’t accidentally dig into pipes and can cause major (read: costly) issues.

The cost to repair a crawl space runs between $1,500 and $15,000, depending on the extent of the damage. Major flooding or water repairs can cost up to $10,000 for removal and repairs. If you simply need to clean your crawl space, expect to pay between $2,000 and $6,000 for a major cleanout. Replacing a crawl space beam due to rot or damage can cost between $1,500 and $5,000, while removing and replacing damaged insulation costs between $1,000 and $4,000.
