FAQ:

Q: What towns and counties do you serve outside of Spokane?
A: While our main shop is based in Spokane, Aspen Excavation LLC regularly services residential and commercial projects throughout Spokane County and surrounding areas. Our service radius frequently includes Cheney, Medical Lake, Airway Heights, Spokane Valley, Liberty Lake, and Deer Park. If you have a rural property or a site project located slightly outside these areas, feel free to reach out to discuss our equipment mobilization options.
​
Q: How deep do you dig utility lines to beat the Spokane winter frost line?
A: In Eastern Washington, utility trenches must be excavated deep enough to protect your lines from freezing and ground settling. For main water lines, we strictly excavate to a depth of at least 36 to 42 inches (3 to 3.5 feet) to sit safely below the local Spokane frost line, adhering closely to Washington State building codes. We also coordinate 100% of the utility utility locates (Call 811) before any tracks hit the ground to ensure safe digging for gas, power, and sewer connections.

Q: Can you help fix gravel driveways that wash out during spring snowmelts?
A: Yes. Severe spring runoffs and freeze-thaw cycles cause heavy potholing and washouts on private rural roads and driveways across the Inland Northwest. We don't just dump gravel over the problem; we use precision grading equipment to crown the road, establish positive drainage slopes, and clear bar ditches. If necessary, we can install heavy-duty culvert pipes at low crossings to divert rushing water safely away from your driveway investment.
