Winery Floor Assessment: What a Zone-by-Zone Review Covers
By Pablo Figueroa · October 20, 2026 · 3 min read
A winery floor assessment looks at each room as its own problem. A crush pad, a tank room and a tasting room share a building but not much else, and an assessment that treats them as one surface misses most of what matters.
What is a winery floor assessment?
A written review of every floor in the winery, room by room. For each zone it records what the floor is exposed to, what condition it is in, whether it drains, and what system would suit it if work is needed. It ends with an order of work set against the winery's calendar.
When is the best time to do one?
After crush, while the floors still show what the season did to them, and before the off-season plan is made. California harvest timing varies by region, grape variety and year. Wine Institute’s harvest reporting describes August starts in several regions and notes that some harvests typically extend into November. Plan repairs around when your own crush pad can be closed. An assessment in the weeks after harvest gives the winery the longest runway to plan, test and schedule.
What does an assessment look at?
By zone:
- Crush pad: slope and ponding, drain edges, joints, traction, wear in forklift lanes
- Tank room: coating condition around drains and valves, cove base, signs of chemical damage
- Barrel room: surface under and between racks, damp areas, thresholds, drains
- Bottling and case storage: joint edges, wheel wear, impact damage
- Tasting room: wear, staining, etching from acidic spills
Where a coating or overlay is on the table, moisture testing under ASTM F2170 comes before a system is chosen. A slab on grade in a cool cellar does not have one moisture condition.
What do you get at the end?
A written summary: what we see in each zone, what is urgent, what can wait, which system fits each zone, and the order of work. It is a planning document, not a sales quote, and it is free whether or not you hire DTI for the work.
How should you prepare?
Gather four things: a floor plan, the list of cleaning products and how they are mixed and used, the equipment that runs on each floor, and photos of any problem spots. The cleaning list matters most. A floor can only be matched to its exposure if the exposure is written down.
How does this differ from a general floor-condition assessment?
DTI's standard floor-condition assessment is a walk-through with a written summary. A winery zone assessment is organized around the rooms a winery actually has and the way they are used through the year.
