Drying a building that cannot stop working

Commercial losses change the arithmetic in two ways. The volumes are larger, and the building usually has to keep running while it dries. A warehouse floor is a concrete slab holding more water than any wood frame house, and the product stacked on it wicks from the bottom pallet up, so the clock on the contents is shorter than the clock on the structure.

Where the water comes from in a commercial building

Residential losses run heavily to supply lines and appliances. Commercial losses have a different distribution. Roof drains and internal leaders on a flat roof are the first: a blocked drain ponds water on a membrane that was never designed to hold it, and the failure comes through at a seam or a penetration, over whatever is stored below. Fire sprinkler systems are the second, and they cause a surprising share of the total, because a wet-pipe system holds water in every line all the time. An impact from a forklift mast, a corroded head, or a run of wet pipe in an unheated section that freezes will discharge until someone finds the control valve.

The third is scale. A commercial water heater, a boiler, a cooling tower makeup line or a rooftop unit's condensate pan holds and moves considerably more water than a house does, and a failure that runs overnight in an unstaffed building has hours nobody is watching. The fourth is the same rain and sewer surcharging that reaches houses, arriving at a building with far more floor area for it to spread across.

The freight belt at West Memphis

West Memphis sits on the Mississippi's west bank at the interchange of Interstate 40 and Interstate 55, and it has been a freight hub since I-55 opened in the 1950s. Trucking and distribution operations including Schneider National Carriers, FedEx National LTL and a Family Dollar distribution center are among its major employers, alongside Southland Park Gaming and Racing near the interchange, which has operated since 1956. The city's fire department covers about twenty-nine square miles containing two interstates and three railroads. Marion, five and a half miles away, carries its own distribution and manufacturing footprint; the Hino Motors plant there ran until its closure was announced in June 2024, a loss of about thirteen hundred jobs.

That building stock is what shapes the work. Distribution buildings are large-footprint, slab-on-grade, with racking bolted into the floor and inventory sitting directly on it. Ground conditions do not help: the county is Mississippi bottomland with alluvial sediment more than a hundred feet thick and heavy Sharkey clay at the surface, and West Memphis itself is only about eleven feet above the level of the river. In 2024 the city was awarded a $16 million federal PROTECT grant to restore hundreds of acres of riverfront wetlands so they can absorb floodwater before it threatens I-40 and I-55, which is a fair measure of how much water the flat ground there has to deal with.

Concrete is the whole job

A wood-frame house dries because water leaves relatively thin members. A concrete slab is a different problem. Concrete is porous, holds a great deal of water, and releases it slowly from depth, and the water at the bottom of the slab has to travel all the way to the surface before a dehumidifier can take it. Surface readings taken with a hand meter tell you almost nothing about that, which is why slab moisture on a commercial job is assessed with probes set into holes drilled into the slab and left to equilibrate.

That distinction becomes expensive at the flooring stage. Vinyl composition tile, sheet goods, epoxy and resilient plank are all vapor-tight to some degree. Installed over a slab that still holds moisture, they trap it, and the adhesive fails, the tile lifts or the coating blisters months after everyone signed off. Getting the slab genuinely dry before the floor goes back is the difference between finishing the job once and finishing it twice.

Racking and product add a second front. Corrugated cardboard wicks water more readily than anything else in a warehouse; a pallet sitting in a quarter inch of water will have carried moisture up through three or four cartons before anyone gets to it. Product triage is therefore its own operation, run in parallel with structural drying: get the bottom layers off the floor, separate what is wet from what is only sitting near water, and document as you go, because the inventory loss is usually the larger figure in the claim.

Drying around an operating business

The practical constraint on almost every commercial job is that the building has payroll attached to it. Work gets staged so that the smallest possible area is out of service at any one time, and so that the noisiest and dustiest phases happen when the building is empty.

Containment does double duty here. Sheeting off a wet zone lets the dehumidification concentrate where the water is, and it also keeps the rest of the operation running with a clear boundary between the work and the business. Power is a real planning item, because commercial drying equipment draws far more than a few household circuits will carry, and on a large job the equipment gets fed from a temporary distribution setup rather than from whatever receptacles are on the wall. Where a business runs around the clock, monitoring and equipment adjustments get scheduled to the shift pattern rather than to daylight.

• Establish who controls the shutoffs and the sprinkler control valve before anything else, and confirm the fire system will be restored to service.
• Document the loss room by room with readings and photographs before material moves, since a commercial claim is settled on records.
• Stage contents out of the wet area first, bottom layers before top, and separate wet from dry immediately.
• Contain and dry in zones so the business keeps operating in the unaffected footprint.
• Verify the slab with in-place probes rather than a surface meter before any flooring is reinstalled.
• Coordinate with the landlord or property manager early, because the split between building and tenant improvements decides who authorizes what.

Upriver, the same problem in a different building

The Arkansas River Valley has its own commercial exposure. When the river crested at Van Buren at 40.79 feet on June 1, 2019, the port there closed along with the ports at Tulsa, Muskogee and Little Rock, and businesses in Van Buren and across the river were flooded. In Franklin County during the same event, the AR-23 bridge in southern Ozark and AR-22 west of Charleston both closed and effectively split the county, which is a reminder that a commercial water loss can be complicated as much by access as by the water itself.

Municipal capacity is a live issue in that part of the footprint. Mulberry has broken ground on a $12.2 million water treatment plant expansion, 68 percent grant-funded, to serve new commercial and residential development. Ozark's council was told in November 2025 that maintaining the city water system's current level of service would cost $22.9 million, with total infrastructure needs above $90 million, and voted not to open talks about supplying water to a proposed state prison for lack of capacity. For a business owner, that is context for what happens after a main break or a large discharge: the system feeding the building has its own limits.
