Frequently Asked Questions

Common questions about underground utility installation in Allen

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

Shallow utilities freeze during rare hard freezes, crack under vehicle loads, or get struck during future landscaping. Code violations halt construction and require expensive re-installation. Proper depth in Allen clay soil prevents frost damage and meets Collin County inspection standards, avoiding $8,000+ in re-work costs.

Hitting unmarked gas, water, or electrical lines causes service outages, emergency repairs, and potential fines. Striking fiber optic cables can cost $50,000+ in damages. Pre-drilling utility locates identify all existing infrastructure, preventing strikes that halt work and trigger liability claims.

Water lines require 18-24 inches minimum, sewer lines 24-36 inches, and electrical conduits 18-24 inches depending on voltage. Allen clay soil and Collin County codes dictate specific depths for frost protection and load bearing. We verify depth compliance before backfilling.

Yes. Horizontal directional drilling and auger boring install water, sewer, and electrical lines under roads with entry and exit pits only. This eliminates road cuts, restoration costs, and traffic disruption common with open trenching methods.

Horizontal directional drilling uses steerable boring to install pipes and conduits under obstacles like roads, driveways, and slabs. It's ideal for crossing under paved surfaces or preserving landscaping on Allen estate properties. The method creates minimal surface disruption compared to open trenching.

We compact backfill in lifts, use engineered bedding around pipes, and allow settling time before final grading. Allen clay soil requires moisture control during backfill to prevent voids. Proper compaction eliminates settling that cracks joints or separates pipe sections within the first year.

Costs vary by distance to mains, number of road crossings, and soil conditions. Horizontal directional drilling typically costs more upfront than open trenching but eliminates landscaping restoration expenses. We provide site-specific quotes after surveying your Allen property and planning bore paths to existing mains.
