What Crom does

CROM, founded in 1953 in Gainesville, Florida, by J.M. Crom and his sons, is a privately held water infrastructure solutions provider specializing in the design, construction, restoration, and maintenance of prestressed concrete tanks and related structures for water and wastewater applications. The company's core technology, pioneered by J.M. Crom Sr. in 1942, combines a galvanized steel shell diaphragm encased in high-velocity shotcrete, wrapped in prestressed wire, and finished with an outer shotcrete layer to produce watertight tank walls with 50+ year service lives. CROM has built over 4,400 prestressed concrete tanks globally with capacities ranging from 35,000 to over 30,000,000 gallons, and the technology has become so synonymous with the category that 'CROM tanks' is a generic industry term. In 2023 the company extended its offering with CROM² & CROM SQUAREd watertight tensioned straightwall tanks, and in 2026 it launched NXT|MBR, a Permanent Concrete Modular wastewater treatment system in partnership with Integrated Water Services.

CROM operates a vertically integrated design-build model serving municipalities, industrial clients (energy, pulp and paper, food and beverage), commercial properties, federal agencies, and mining operations. Revenue is generated through project-based contracts for new tank construction, restoration and maintenance services (which constitute over half of revenue per company commentary), continuing 24/7 service agreements, and inspection/asset management work delivered through subsidiaries including CROM|MW (Mountain West Tank Resources), CROM|CFG, and CROM|CMT. Pricing is custom and quote-based on a per-project basis with multi-year contracts. Distribution is exclusively direct enterprise field sales, executed through 8 regional offices and a workforce of nearly 700 employees. The company holds rare industry credentials including AMPP QP 8 Accreditation (one of 25 worldwide) and ASA Qualified Shotcrete Contractor status (one of 30), and pursues aggressive inorganic growth — completing three acquisitions in 2025 alone (CMT/WTS, CFG Industries, Mountain West Tank Resources) while adding a new CFO to professionalize finance.

The company's customers span U.S. municipalities (Town of Robbinsville NC, City of Frankfort KY, Johnson City TN, Metro Water Services Nashville, City of Florence AL, Boynton Beach FL) and large industrial enterprises (Exxon Mobil's Corpus Christi plant, unnamed data center projects). The acquisition of new CFO Dan Tews in December 2025 and the establishment of new product lines in wastewater treatment (NXT|MBR) suggest the company is positioning for a broader role as a turnkey national infrastructure solutions provider, leveraging its brand-equivalent status in prestressed concrete tanks and its expanding service portfolio.

Revenue model

1. Prestressed Concrete Tank Construction: Design and construction of new prestressed concrete tanks with capacities ranging from 35,000 to over 30,000,000 gallons. Tanks are used for potable water storage, wastewater treatment, fire protection, and industrial process water storage. This is a project-based, one-time revenue stream executed through design-build contracts.
2. Restoration & Maintenance Services: Over half of CROM's revenue comes from its Restoration Services division, which includes durability inspections, concrete removal, high-performance coatings, infrastructure upgrades, structural solutions, and shotcrete applications. This provides recurring project-based revenue from existing infrastructure.
3. CROM² & CROM SQUAREd Straightwall Tanks: New product line for rectangular/longitudinal prestressed concrete tanks launched to serve a parallel market. Provides five-year watertightness warranty versus one-year typical for cast-in-place alternatives.
4. Continuing Service Agreements: 24/7 restorative and emergency service agreements for ongoing asset protection, inspection, and maintenance of water infrastructure. Provides recurring revenue from existing client base.
5. Tank Inspection & Asset Management: CROM|MW subsidiary provides inspection, condition assessment, coatings evaluation, cathodic protection support, and lifecycle planning services for water utilities. Project-based and potentially recurring through asset management agreements.
