Grocery Store Receiving Area Flooring: What the Backroom Floor Needs

By Pablo Figueroa · October 15, 2026 · 3 min read

The receiving area is a small part of a grocery store's floor and carries most of its heavy traffic. Loaded pallets, jacks, and sometimes forklifts run the same lanes every day, in wet conditions, and the floor is often just the sales floor spec carried through the back doors.

What loads does a grocery backroom floor actually carry?

A loaded pallet on a manual or electric jack puts its weight through a few small, hard wheels, so the stress under each wheel is high and lands in the same lanes repeatedly. Some stores also run a forklift. The floor should be specified from the real equipment: the heaviest loaded pallet, the jack or lift type, and how many passes a lane takes in a day.

Why do the joints fail first?

A hard wheel hits the edge of a joint every time it crosses. Over hundreds of passes the edge spalls, the joint widens, and the next wheel hits harder. Semirigid joint filler supports the edges and carries load across the gap. Concrete keeps shrinking for years, most of it in the first year and especially the first 90 days, so the timing of the filler matters. Filler manufacturers commonly recommend 28 days, and ACI 302.1R-15 advises delaying as long as possible and cites 90 days.

Does the dock apron need a different design than the interior?

It should be designed for its own loads. Trailers set landing gear down on a small footprint, and the dock edge takes impact from plates and trailer movement. Slab thickness, base preparation, and edge detail for the apron and any dock pit are set for those conditions, not for the sales floor.

What about wet conditions and spills?

Receiving stays wet from produce prep, cooler melt, wash-down, balers, and spills. Staff walk this floor all shift, so slip resistance should be tested wet here too. Spilled dairy, juice, and brine can attack bare concrete and under-specified coatings over time, so the system should be checked against what actually gets spilled, along with cleaners and hydraulic fluid. Floor drains and slope to drain keep standing water out of the pallet lanes.

Is the door between the backroom and the sales floor part of this?

Yes, and it is often the weak point. A loaded jack or cart crosses it slowly over a joint or a change in surface. It needs a detail of its own: protected joint edges, no abrupt change in height, and a surface that holds up to point loads.

How DTI approaches receiving and backroom floors

We specify the backroom as its own zone: real loads, joint layout against traffic lanes, a wear-rated surface, wet slip testing, drainage, and a detailed door threshold. For the full eight-point checklist, see this week's edition of The Floor Front, our LinkedIn newsletter.
