Frequently Asked Questions

Common questions about underground utility installation in Arlington

Answers about trenchless methods, depth requirements, and Arlington clay soil conditions.

Delaying utility connections means your underground home sits incomplete without water, sewer, or electrical service. Rushing installation later often requires emergency permits and higher costs for expedited drilling. Early planning locks in trenchless methods that preserve landscaping and avoid costly road restoration after surfaces are finished.

Unmarked water, sewer, or electrical lines get damaged during excavation, causing service outages, emergency repair costs, and project delays. We locate all existing utilities before drilling to avoid conflicts. Hitting a gas line or electrical conduit can halt construction for weeks and add thousands in repair expenses.

Dallas codes require water lines buried 30-36 inches deep, sewer lines 24-36 inches, and electrical conduits 18-24 inches depending on voltage. Arlington clay soil and limestone bedrock affect excavation methods. We verify depth compliance for all installations and coordinate with local inspectors for final approval.

Yes. Horizontal directional drilling installs pipes and conduits under Arlington roads, driveways, and slabs without surface trenching. We coordinate road crossing permits with Tarrant County and handle all required inspections for compliant installations.

Horizontal directional drilling uses steerable boring equipment to install pipes and conduits underground with minimal surface disruption. A pilot bore creates the path, then reaming enlarges the hole, and pipe pulling installs the utility line. This method avoids tearing up yards or crossing roads with open trenches.

Clay soil with limestone presence requires adapted excavation techniques to avoid equipment damage and meet depth requirements. We use trenchless methods suited for Arlington geological conditions and verify backfill compaction to prevent settling after installation.

Costs depend on utility type, crossing obstacles, and drilling distance. Horizontal directional drilling under roads costs more than open trenching but avoids road restoration expenses. We provide site-specific quotes after assessing your Arlington property and utility connection requirements.
