SHMAK LLC — Industrial Concrete Flooring, Nationwide

What we install

Five specialties, one crew standard. SHMAK self-performs every scope below — no hand-offs, no learning on your slab.

01

Polished Concrete

Grind, densify, and polish to the specified sheen and aggregate exposure. A low-maintenance, forklift-tough finish that brightens big-box industrial space and cuts lighting load.

02

Epoxy & Resinous Flooring

High-build epoxy and resinous systems for production areas, battery rooms, and food-grade facilities — chemical-resistant, seamless, and striped to your traffic plan.

03

Slab Moisture Remediation

Sweating-slab syndrome diagnosis and permanent remediation. We test, identify the moisture drive, and treat the slab so finished floors stop failing and forklifts stop sliding. It is our signature specialty — see how we fix it.

04

Densifier & Sealing

Lithium densifier and guard applications that harden dusting slabs, increase abrasion resistance, and extend the life of existing concrete without a full polish.

05

Joint Fill & Repair

Control-joint filling, spall repair, and crack remediation that protect slab edges from forklift impact and keep AGV and high-traffic aisles running smooth.

The sweating slab is our signature

Most flooring contractors won't touch a sweating slab. It's the call SHMAK built its name on — diagnosed, treated, and verified dry by our own crews, nationwide.

What it is

Sweating slab syndrome: when warm, humid air meets a cool concrete slab, moisture condenses across the surface — the floor quite literally sweats. It shows up as a dark, damp sheen, wet tire tracks through the film, and white efflorescence blooming as the moisture cycles. It isn't a leak, and mopping doesn't fix it.

Why it matters

A floor people can fall onA condensation film turns pedestrian lanes into a slip hazard — and a safety and liability problem with your name on it.
Forklifts lose tractionA wet film under load means longer stops and sliding turns — near-misses at rack ends and dock doors.
Product and packaging sufferMoisture wicks into pallets and cartons staged on the slab, and coatings blister and let go over it.

How SHMAK fixes it

01

Assess & test

On-site moisture and dew-point testing confirms the slab is sweating — not leaking — and maps how far the condition runs.

02

Deep clean

The surface is scrubbed and stripped of contaminants, so treatment reaches the slab instead of sitting on top of the grime.

03

Treat & densify

Our treatment and densifier system goes down across the affected zones, locking the surface down and shutting the sweat off at the source.

04

Verify dry

We re-check the treated slab and walk it with you — dry, sealed, and back in safe service. Documented, not just promised.

Floors we fix

Most of our calls start with a floor that looks like one of these — photographed on real SHMAK job sites. Moisture, cracking, and failing surfaces are exactly what our treatment systems are built to reverse.

Concrete surface broken up and deteriorated by moisture damage

Moisture-Damaged Slabs

Sweating-slab syndrome and vapor drive that blister coatings, darken concrete, and turn forklift lanes into skating rinks. We test, treat, and seal the slab at the source.

Cracked & Crumbling Surfaces

Map cracking, spalling, and surface delamination that shred tires and trip pedestrian traffic. We remove the failed material and rebuild a sound, sealed surface.

Section of concrete slab shattered and broken apart

Shattered, Failing Concrete

Slabs too far gone for a coating alone. We cut out the failure, repair the section, and finish it to match the surrounding floor — traffic-ready, not patched-looking.

Failed Control Joints

Open, raveling joints that hammer forklift wheels and telegraph through the whole slab edge. We rout out the failure and refill flush with semi-rigid joint filler.

Debris-Filled Joints

Once filler lets go, joints pack with grit that locks the slab and chips the edges with every pass. We clean them out to sound concrete and refill them right.

Delamination

Surfaces and coatings letting go in sheets — usually moisture or a bad bond underneath. We strip it back to sound slab and rebuild the system on a tested profile.

Spalled, broken concrete where two joints cross

Spalling at Joint Crossings

Joint intersections take the worst of forklift traffic and break down first. We rebuild the corners and edges so crossings stop eating wheels and product.

Failed Patches

Somebody else's quick fix, already cracked and lifting. We remove patches that were never bonded and replace them with repairs built to carry traffic.

Joint failure, up close

This is what failed joint filler actually looks like on the floor — and why "fill it again the same way" never lasts.

Exterior restoration

The same surface discipline, outside the dock doors. SHMAK restores exterior concrete and building surfaces — loading pads, docks, sidewalks, and drive lanes — stripping off years of rust, staining, and biological buildup that most people assume is permanent.

Rust & stain removal

Battery-acid and irrigation rust, oil, and tire staining — lifted with professional rust-removal chemistry in the F9 BARC class, matched to the stain so the concrete underneath survives the cure.

Mold & mildew buildup

Black and green buildup on shaded concrete and building exteriors, removed with professional mold-stain systems in the RMR-86 class — cleaned down to sound surface, not just lightened on top.

Exterior concrete restoration

Cleaning, grinding, and sealing that brings pads and aprons back to a uniform, serviceable finish — proven on a test patch first, so you see the result before committing to the whole pad.

Before / after — the treatment line

No staging, no filters: the exact moment treated concrete meets untreated on live SHMAK jobs. The dark, moisture-stained side is what we were called in for; the gloss side is what we leave behind.

Warehouse floors at full scale

This is the work SHMAK mobilizes for: entire distribution floors, finished bay after bay by our own crews — stained and polished at one end of the country, sealed bright white at the other.

Fort Worth, TX — existing conditions, documented on site

Every SHMAK program starts with a documented condition survey. These frames are from our September 2026 walk of the Lovett Ave facility in Fort Worth — staining, failing joint filler, and spalled joints, all scoped before the phased treatment program begins.
