Excavating questions, answered by experts

Silt fences should be trenched 8 to 12 inches deep to prevent sediment-filled water from escaping underneath. It also helps to anchor the fence during wet, windy weather. The silt fence fabric often has a red line to indicate the depth for digging. A good contractor will be familiar with the guidelines and regulations.

To determine whether your homeowners' insurance will cover crawl space repair, consider the cause of the issue. Repair may be covered if the problems were caused by an event that the insurance covers, such as vandalism or a windstorm. However, companies won't cover the repair if the issues are caused by neglect or wear and tear.

Trenches are typically 12 inches to 24 inches deep and 8 inches wide. However, your city or county may have specific ordinances that clarify the dimensions needed for the project. For instance, a water pipe may need to be 24 inches deep, but a drainage pipe may need to be 36 inches deep.

The average cost for pool excavation is $2,500. This cost can range from $450 to $4,500, depending on the pool shape and size, time of year, and any need to move buried utilities. 

When excavating for your pool, you might have to move existing utilities. You can expect to pay an additional $15 to $25 per linear foot to move gas lines. To move a septic system, it’ll cost an additional $2,000 to $20,000. A pool that is 10 feet by 12 feet averages $450 to excavate, and a 20-foot-by-40-foot pool averages $3,020.

It all depends on the scope of the project. A trencher can certainly save time and energy, but you might not need to dig that deep in the first place. Aside from the depth of the trench, the quality of the soil matters. If it’s light, soft soil, you might try a shovel first. However, if the soil is rocky and hard or there are obstructions in it, like tree roots, a machine trencher might be the better option.
