Sleeper system floors
Coating and sealing the concrete beneath a raised sleeper subfloor before the finish floor goes down.
The build-up, step by step
Every sleeper system floor job Shanks installs follows the same order, because skipping a stage is how floors fail. Taylor is on site for all of it.
Expose the slab
The existing subfloor is lifted so the concrete underneath can be seen and tested.
Moisture test
Slabs under sleeper systems are the ones most likely to be holding moisture, and it gets measured rather than assumed.
Seal the concrete
A moisture-tolerant primer or vapor-reducing membrane goes onto the slab.
Rebuild
Sleepers and subfloor go back down over a slab that is no longer feeding moisture into them.
Right room, right system
Basements and additions where a wood subfloor sits on sleepers over concrete, especially where flooring above has cupped or smelled musty.
Where it is the wrong call
Situations where the real problem is exterior drainage. Sealing the slab will not fix water running at the foundation.
Back in service: Membranes are ready for the subfloor within a day.

Why this floor costs what it costs
A quote on this work is really a quote on preparation. Here is what Taylor is looking at when he walks a floor:
Condition of the slab
A clean, sound slab grinds in a morning. One carrying old paint, carpet glue, or a failed coating can take a full day longer before anything can be applied.
How much repair it needs
Cracks, spalled edges, pitting and old anchor holes are filled and ground flush before coating. A slab that needs a lot of this can add a day on its own.
Size and shape
Bigger floors cost less per square foot, because the setup, the mixing and the cleanup are much the same whether the room is 400 or 1,400 square feet. Cut-up rooms with lots of edges take longer than open ones.
Which system you choose
Build thickness and the chemistry of the topcoat are the two biggest material costs. A heavier commercial build genuinely costs more than a residential one.
What Alabama slabs do
Freeze-thaw cycling here is mild compared with the north, but it is real, and it is what turns a hairline crack in a porch or a garage apron into a spalled edge over a few winters. Cracks get filled before they are coated, not after.
Alabama humidity is the quiet variable in this work. Resin cures on a temperature and dew-point window, so a floor is scheduled around the weather rather than squeezed in before a storm rolls over Talladega.
Where the trailer goesWhat the days actually look like
The schedule matters as much as the finish when it is your garage or your shop. A normal run:
Before Taylor arrives
The room has to be completely empty, including anything mounted low on the walls if the coating is being coved up. Freezers and fridges need somewhere else to live for a few days, and the breaker for the room should be reachable.
Grinding day
The loudest day. Grinders run on HEPA vacuums so dust stays contained, but it is not quiet, and it is worth knowing that in advance if somebody works from home.
Coating days
Once resin is down, the room is closed. Pets and children need to stay out, and doors get taped so nobody wanders in overnight.
Getting it back
Foot traffic the next morning. Vehicles wait the full window, and putting a car back early is the one shortcut that visibly damages a new floor.
Keeping it looking new
Once the membrane is down and the subfloor is rebuilt, the concrete needs nothing from you. What matters is keeping the finish floor above it dry: wipe up spills rather than leaving them, keep the space heated or dehumidified through the wet months, and if a musty smell ever comes back, that is the signal to look at the exterior drainage rather than the slab.
Anything Taylor installs comes with a walk-through at handover covering exactly this, plus what to avoid in the first two weeks while the coating reaches full hardness. If something does go wrong later, tell him about it rather than living with it.
The owner is the installer
Shanks Concrete Coatings is Taylor and Heather Shanks, working out of Anniston. Taylor trained directly with Brian Phillips, The Epoxy Dude, in southern Indiana, and he runs the grinder and pulls the squeegee on every job himself. Licensed and insured, Alabama #2602341.
If a sleeper system floor floor is not the right answer for your room, he will tell you that on the first visit rather than sell it to you. More about how Shanks works, or send over the details of your floor.
Sleeper System Floor questions
How do I know if my slab is the problem?
Cupped boards, a musty smell after rain, or adhesive that will not hold. A calcium chloride or RH probe test settles it.
Can you do this without pulling the floor?
No. The slab has to be reachable to be treated, and the point of the work is the surface underneath.
Is a vapor barrier enough?
A sheet barrier helps but does not bond. A liquid-applied membrane bonds to the slab and cannot be punctured during the rebuild.
Does this fix a wet basement?
It stops vapor moving through the slab. Liquid water entering at the walls or footing is a different repair.
Will this stop the floor above from squeaking?
No, that is a fastening issue in the subfloor itself. What it stops is the moisture that makes boards cup, swell and eventually let go of their adhesive, which is a different problem with similar symptoms.
Four questions worth asking any installer
Ask these of Shanks and of whoever else you are talking to. The answers separate a floor that lasts from one that looks good for a season, and a straight installer will not mind being asked.
How are you preparing the slab?
The only acceptable answers involve a diamond grinder or a shot blaster. Acid etching and a scrub with degreaser is not preparation, and it is the single most common reason a coating lets go.
Are you testing for moisture?
On any basement or ground-level slab this should be a yes with a number attached. Vapor pressure will push a coating off no matter how good the product is.
Who is actually on my floor?
Worth asking whoever quotes you. With Shanks the person who quotes it is the person who grinds it and coats it, and that is not true everywhere.
What is the topcoat?
A UV-stable polyaspartic or aliphatic urethane holds its color. A cheap job leaves a standard epoxy as the top layer, and it will amber in daylight within a year or two.
Other systems for the same room
Sleeper System Floor is one of twenty-two systems Shanks installs. If the room is telling you something different, these are the closest alternatives, and Taylor will happily point you at the cheaper one if it is the right answer.

Another system Shanks installs across the same sixty-mile area.
Metallic Epoxy
Another system Shanks installs across the same sixty-mile area.
Garage Floor Epoxy
Another system Shanks installs across the same sixty-mile area.
