Frequently Asked Questions
How deep does a foundation need to be excavated?▼
Foundation depth depends on local frost lines, soil conditions, and building design. In northern states, footings must extend below the frost line (up to 48 inches or more). In southern states, shallower depths may be acceptable. Basements require excavation to 8 to 10 feet below grade. A structural engineer or building code official determines the required depth.
What is a utility locate and why is it required?▼
A utility locate (811 call) identifies buried gas, electric, water, sewer, and communication lines before excavation begins. It is required by law in all 50 states. Utility companies mark their lines with color-coded paint or flags within a few business days. Excavating without a utility locate can result in line strikes, service outages, injuries, and significant fines.
How much does excavation cost?▼
Excavation costs vary widely based on scope, soil conditions, depth, access, and equipment required. Typical ranges are $2,000 to $10,000 for utility trenching, $5,000 to $20,000 for foundation excavation, $10,000 to $40,000 for full basement excavation, and $3,000 to $15,000 for site grading. Rocky soil and limited access increase costs significantly.
What happens if you hit rock during excavation?▼
Rock encountered during excavation must be removed by mechanical breaking (hydraulic hammer), chemical expansion agents, or in some cases, controlled blasting. Rock removal significantly increases project cost and timeline. A geotechnical survey before construction can identify rock conditions and allow accurate budgeting.
Do I need a permit for excavation work?▼
Most jurisdictions require permits for excavation associated with construction projects, grading that changes drainage patterns, work near waterways or wetlands, and septic system installation. Utility trenching may require separate permits. Your excavation contractor should know local requirements and can typically handle permit applications.
