Frequently Asked Questions

Tarsco provides inspection services to assess existing tanks and develops repair specifications that restore performance.

Project duration varies with tank size, complexity, and site conditions, but Tarsco's factory fabrication model accelerates timelines compared to field-welded construction.

For liquid containment, yes - a sealed bottom (steel or concrete with membrane liner) is essential. Exceptions are special foundations with certified liners. Bottom choice depends on fluid, hygiene, and code/secondary containment needs.

Tarsco provides comprehensive handover packages, including as-built drawings, material certifications, coating records, QA/QC reports, and operation and maintenance guidance.

A tank assembled from steel plates and fully welded at the jobsite. After welding, seams are inspected (e.g., radiography/vacuum) and the exterior/interior are coated in the field. Best for very large diameters or custom geometries.

A tank welded at the factory and shipped as a single piece or large sections. Quality control is high, but size is limited by transport. Common for smaller volumes, lube/fuel, or specialty process tanks.

A vessel designed to safely store liquids or dry bulk. Materials and design follow applicable codes, with appurtenances (nozzles, vents, manways), corrosion protection, and level/overfill safeguards.

A tank installed at or above grade (not buried). Easier to inspect and maintain; used for water, fuels, chemicals, and fire protection. Must meet relevant codes and secondary containment where required.

A lightweight, corrosion-resistant geodesic dome roof for tanks. It’s self-supporting (no internal columns), reduces emissions/infiltration with seals, and withstands wind/snow with minimal maintenance.

Common options are reinforced concrete ringwall or slab with anchor bolts. Choice depends on soil report, loadings, and whether a steel bottom or membrane over concrete is used. Flatness and level tolerances are critical for leak-tight assembly.

Factory application controls temperature, humidity, surface preparation, and application technique in ways that field coating cannot match.

Controlled steel sourcing, surface prep, factory coatings with DFT/holiday testing, gasket and bolt certification, panel tolerances, and serialized tracking. In the field: calibrated torque checks, coating touch-up inspection, and hydrostatic/leak tests.

Bolted: modular panels, factory coatings/liners, fast erection, easy expansion/repair; ideal for atmospheric service. Welded: monolithic shell, best for custom shapes/pressure or certain chemicals; more site work and coating in the field.

AWWA D103 specifically addresses factory-coated bolted steel tanks for water storage, making it the primary reference for municipal water applications. NFPA standards govern fire protection and water storage. FM approval is common for tanks serving critical fire suppression systems.
