Closet and Garage Storage Cabinets on Slab Floors

A slab floor is supposed to stay put. In much of Austin, TX it moves, because the clay soils east of the Balcones Fault swell when wet and shrink in drought, and a cabinet screwed down hard will follow the slab. The breakdown sitting on austin custom cabinets roger ueths garden lists what to build in so a closet or a garage wall of storage keeps its doors aligned through seasons of that movement.

Why the floor moves

Rain spread through the year and long dry spells make the clay beneath a slab cycle. The effect is small, perhaps a quarter inch over a long wall, but enough to rack a tight door. Houses to the west, on limestone near the Balcones Escarpment, move less, so a cabinet plan starts by asking what the ground under the house is.

Building the base to shim

The carcass sits on a separate toe kick or leveling leg so it can be adjusted years later with a screwdriver. A long run of garage cabinets is split into units of four feet or less, joined at the face frame with a small reveal rather than one continuous top. A plywood box in birch holds fasteners and resists garage heat, where melamine over mdf swells if the edge banding lifts.

Closets: hardware and depth

A closet run works at twenty four inches deep for hanging and twelve to sixteen for shelves. A drawer box with a dovetail drawer corner carries folded clothes without sagging, and a full extension drawer slide with soft close keeps it quiet. Frameless boxes use space well in a tight closet, while a maple face frame adds rigidity where the wall is uneven.

Garage conditions

A garage in an Austin summer runs well above house temperature, and thermofoil doors can peel there. Painted slab door fronts on sturdy plywood, or refinishing an oak door, hold better. Wall hung uppers anchor into studs on a rail, and base cabinets sit two inches off the slab so a spilled bucket does not wick into the box. A freeze roughly every two years is rarely hard enough to harm a cabinet, but the swings between cold nights and hot afternoons are. Doors are hung last, after the units are leveled and fastened, so the reveals can be set against the floor as it actually sits that season. A second adjustment visit after the first wet spring is common.
