Process & Underground Piping

HDPE fusion, ductile iron, stainless, and double-contained chemical drains with full testing and documentation.

Industrial Utilities, Process Lines & Below-Grade Systems

AJR installs process and underground piping that ties safely into operating plants. From firewater mains and industrial water to chemical drains and force mains, our crews deliver clean trenching, disciplined testing, and complete turnover packages.

We coordinate permits, traffic control, and locates; provide shoring and dewatering as needed; and stage work to avoid production impacts. Materials include HDPE (butt fusion/electrofusion), ductile iron, stainless, carbon, PVC/CPVC, and double-contained systems for corrosives. Each system is tested, disinfected where applicable, and documented with as-builts for a smooth handoff.

Process & Utility Lines

Chilled/industrial water, condensate return, air, nitrogen, chemical feed and return, sanitary and storm systems, and firewater loops.

HDPE Fusion & Specialty Plastics

Butt fusion and electrofusion with calibrated equipment; restrained joints and fittings; double-contained drains with leak-detection ports.

Ductile Iron, Stainless & Carbon

Buried and abovegrade transitions, thrust blocks, restrained joints, corrosion protection, and specialty coatings where specified.

Structures & Appurtenances

Manholes, catch basins, cleanouts, valve vaults, air release valves, bollards, and concrete encasement per detail.

Testing & Disinfection

Hydrostatic and pneumatic tests, chlorination/dechlorination for potable/industrial water, CCTV where required, and certified results.

As-Builts & Turnover

GPS/as-built updates, flushing plans, compaction and backfill records, O&M documentation, and clear close-out packages.

Why AJR?

Safe Trenching & Tie-Ins

Competent-person oversight, shoring and trench boxes, line breaks and permits, and coordinated tie-ins to minimize downtime.

Built to Spec

Disciplined QA/QC with fusion logs, torque logs, test reports, and coating/DFT records maintained for your files.

Clean Turnover

As-builts, location data, and documentation packaged clearly so maintenance teams can own the system from day one.
