Most Frequently Asked Questions

How deep can you bore and how far?
Our underground boring equipment typically operates 2 to 10 feet deep for residential projects in Rancho Cucamonga and Corona, though we can go deeper for special applications. Standard boring runs reach 200 feet in a single shot, with longer distances possible using multiple setups. We adjust depth based on utility requirements, frost lines, and existing underground obstacles. Most residential bores for water or electrical lines run 3 to 4 feet deep.
How much does underground boring cost?
Underground boring typically costs $30 to $80 per linear foot in Fontana and surrounding areas, depending on pipe size, depth, and soil conditions. While this seems higher than trenching labor alone, boring saves thousands by avoiding surface restoration. A 50 foot bore under a driveway costs around $2,000 versus $8,000 or more to trench, remove concrete, and repour. Most residential boring projects complete in one day without the mess of traditional excavation.
What size pipes can underground boring install?
Underground boring accommodates pipes and conduits from 3/4 inch up to 12 inches diameter for most residential and light commercial projects. Common sizes include 1 inch for irrigation, 2 inch for electrical conduit, 3 to 4 inch for sewer lines, and up to 6 inch for water mains. We match boring diameter to your pipe size plus any required clearance. Larger commercial projects may use specialized equipment for bigger diameters.
What's the difference between boring and trenching?
Traditional trenching digs an open channel across your property, destroying everything above including driveways, sidewalks, and landscaping. Underground boring drills horizontally beneath these obstacles without any surface damage. We only dig small pits at start and end points. This saves thousands in restoration costs and completes faster. For running utilities under any paved or landscaped areas in Fontana, boring beats trenching every time.
