How to Write a Winery Flooring Spec: 8 Decisions to Make in Writing

By Pablo Figueroa · October 30, 2026 · 3 min read

A winery is several floors under one roof: a crush pad, tanks, barrels, a bottling line, case storage and a tasting room. A spec that treats them as one surface will miss most of what each room needs. This guide covers the decisions a winery floor spec has to make in writing, and where to start.

What should a winery floor spec contain?

Eight decisions. If one is missing, someone else will make it for you: the standard detail, the low bidder or physics.

1. Loads, defined completely. Tank feet, rack posts, forklift wheel loads and any line loads, listed in writing for each room.

2. Slab thickness and strength from those loads. Derived from analysis, not copied from the last project.

3. The subgrade, specified and verified. Checked in the field before the pour.

4. Flatness for the traffic. Case storage and aisles that run lift trucks need a stated tolerance.

5. Joints, designed with load transfer. Locations, filler type, fill date and a first-season inspection.

6. The surface system, matched to exposure. Chosen from the real cleaning program, as mixed, and tested for moisture first. ASTM F2170 describes in-situ relative humidity testing; results apply to the time and locations tested, rather than guaranteeing future slab conditions.

7. Winery conditions, by name. Wet rooms and cold rooms need slope to drain and drain details, cove height and terminations, and a moisture test in the room at service conditions.

8. Lifecycle and sequence. The system chosen on cost of ownership, with cure, testing and harvest-season timing written in.

Where does case storage fit?

A case storage area runs like a small warehouse: racking, forklifts and pallet traffic. Decisions 1 through 5 apply directly. DTI's Warehouse Floor Spec Handbook covers it with 12 checklists and 96 checkpoints on flatness, joints, load capacity, racking and distribution floors, coatings and lifecycle cost. The warehouse floor specification checklist walks through the same eight-decision frame for a warehouse.

How do you use a checklist on a spec you already have?

Mark every line pass, fail or silent. Passes are fine and fails are negotiable. The silences are the danger. A spec that says nothing about subgrade or joints has not avoided those decisions. It has delegated them.
