Frequently Asked Questions

Common questions about underground utility installation in Richardson

Answers about trenchless methods, depth requirements, and clay soil installation.

Hitting unmarked gas, fiber, or water lines during boring causes service outages, emergency repairs costing $5,000-$15,000, and potential fines. Ground-penetrating radar and utility locates before drilling prevent strikes and project delays.

Loose backfill around pipes settles over 6-12 months, creating surface depressions that collect water and damage landscaping. Proper compaction in 6-inch lifts eliminates voids, preventing $3,000-$8,000 in yard restoration costs.

Dallas code requires water lines at 30 inches minimum, sewer at 36 inches, and electrical conduits at 24 inches. Depth protects pipes from frost, surface loads, and root intrusion in clay soil.

Horizontal directional drilling uses a steerable drill head to bore under roads, driveways, or slabs with a 2-4 inch pilot hole, then ream and pull conduits through. It avoids surface trenching and costly pavement restoration.

Yes. Horizontal directional drilling and auger boring install water, sewer, and electrical lines in clay soil with minimal surface disruption. Open trenching is used only where obstacles prevent trenchless methods.

Costs vary by distance, depth, and method. Horizontal directional drilling for road crossings runs $50-$100 per linear foot. Open trenching for on-site lines costs $15-$30 per foot. Site survey and permits add $1,500-$3,000.

Yes. Road crossings require city permits coordinating with public works. On-site trenching needs building permits for water, sewer, and electrical connections. We handle all permit coordination with Richardson and Collin County.
