Common questions about underground utility installation in Irving

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

Hitting unmarked water, sewer, electrical, or gas lines during drilling causes service outages, emergency repairs costing $5,000-$15,000, and project delays of weeks. Pre-installation line location with depth verification prevents damage to existing infrastructure and avoids costly emergency callouts.

Shallow utility burial in Irving clay soil exposes water and sewer lines to freeze damage during winter cold snaps and surface load damage from vehicles or equipment. Code violations require re-excavation and reinstallation at proper depth, doubling project costs. Correct burial depth from the start avoids compliance issues and protects lines long-term.

Dallas code requires water lines buried 30-36 inches deep, sewer lines 24-30 inches, and electrical conduits 18-24 inches in Irving clay soil. Depth varies with soil type and surface load. We verify burial depth compliance for all installations to meet local code requirements.

Horizontal directional drilling uses steerable boring equipment to install pipes and conduits under roads, slabs, and obstacles without surface trenching. Pilot bore creates the path, reaming enlarges the hole, and pipe pulling installs the utility line—preserving landscaping and avoiding road restoration costs.

Clay soil requires adapted excavation techniques for stable trenches and proper backfill compaction. Limestone bedrock at varying depths may require rock drilling or route adjustments. We assess soil conditions during site planning and use equipment suited to Irving's clay and bedrock conditions.

Yes. Horizontal directional drilling and auger boring install water, sewer, and electrical lines under roads, driveways, and slabs without surface trenching. We coordinate road crossing permits with local authorities and restore surface with minimal disruption.

Costs vary with installation method, utility type, crossing obstacles, and soil conditions. Trenchless methods cost more upfront than open trenching but avoid road restoration and landscaping repair expenses. We provide site-specific quotes after assessing soil conditions, existing line locations, and crossing requirements.
