Basement slab pushing moisture? ATR tests moisture levels and installs vapor barriers that protect your flooring investment. The critical step most contractors skip.
The problem
Adhesive is releasing, coatings are peeling, flooring is warping, or odors and dampness keep returning.
How ATR solves it
ATR tests the slab and evaluates whether vapor transmission is contributing to the failure.
The problem
Moisture readings exceed the limits of the planned adhesive, flooring, or coating system.
How ATR solves it
ATR installs the appropriate vapor mitigation system before the residential flooring contractor or coating crew begins.
The problem
The concrete feels damp or shows recurring signs of moisture even when there is no visible plumbing leak.
How ATR solves it
ATR investigates the concrete moisture condition and defines the preparation and mitigation scope.
The problem
Installing a finish over an untested slab could lead to failure, rework, and avoidable replacement cost.
How ATR solves it
ATR documents the slab condition and mitigates it when needed before handoff to the finished-floor installer.
Moisture mitigation is the process of testing, diagnosing, and controlling moisture vapor that migrates upward through concrete slabs. Every concrete slab — whether new or decades old — is porous. Water vapor from the soil beneath constantly pushes through the slab toward the surface.
When that moisture hits a coating, adhesive, or flooring material, it causes failure: peeling epoxy, warped hardwood, bubbling vinyl, and mold growth. Moisture mitigation stops this cycle by installing a vapor barrier that blocks the transmission before it reaches your finished floor.
ATR Concrete Technologies uses industry-standard ASTM testing methods and commercial-grade barrier systems to give you a permanent solution — not a temporary patch.
The Minneapolis-St. Paul metro sits on some of the most moisture-prone soil in the Midwest. Understanding the local conditions explains why so many slabs here have moisture problems.
The Twin Cities sit along the Mississippi, Minnesota, and St. Croix rivers. Seasonal water tables rise significantly during spring thaw and heavy rain, pushing moisture directly against basement slabs.
Minnesota's glacial soil is rich in clay, which holds water like a sponge. Clay soil doesn't drain — it traps moisture against your foundation and slab, creating constant hydrostatic pressure.
Harsh winters followed by spring thaw create dramatic moisture swings. As frost leaves the ground, trapped water saturates the soil and intensifies upward vapor drive through concrete.
You can't fix what you can't measure. ATR starts every moisture mitigation project with quantitative testing — not guesswork.
Measures the moisture vapor emission rate (MVER) from the slab surface over 60-72 hours. This test tells us how much moisture is actively moving through the concrete. Results are measured in pounds per 1,000 sq. ft. per 24 hours.
Probes are inserted into drilled holes at 40% slab depth to measure internal relative humidity. This is the most accurate test because it measures moisture deep within the slab — not just the surface. Most coating manufacturers require RH readings below 75-80%.
Every step is documented, every measurement recorded. ATR follows a methodical process to ensure your barrier performs for the life of the building.
We perform calcium-chloride (ASTM F1869) and relative-humidity (ASTM F2170) tests to quantify the moisture level in your slab.
Based on test results, we determine the right mitigation system — topical barrier, penetrating sealer, or full vapor-barrier membrane.
The concrete is profiled using diamond grinding to ensure a clean, porous surface for maximum barrier adhesion.
We apply the selected vapor-barrier system in strict accordance with manufacturer specs, ensuring full coverage and proper mil-thickness.
Post-install moisture readings confirm the barrier is performing. We provide documentation and warranty details.
Moisture mitigation is essential anywhere a concrete slab meets a finished floor, coating, or adhesive-applied material.
Protect finished basements from moisture vapor that damages flooring, drywall, and stored belongings.
Ensure epoxy and polyurea coatings bond properly by addressing sub-slab moisture first.
Warehouses, retail floors, and office buildings with concrete slabs on grade need moisture control.
Install vapor barriers during the build to prevent moisture issues before they start.
If you're seeing any of these warning signs, moisture vapor is likely compromising your slab. Don't install flooring or coatings until you test.
Not sure if you have a moisture problem? ATR offers free on-site moisture assessments for Twin Cities homeowners and businesses. We'll test your slab and give you straight answers — no sales pressure.
Moisture mitigation requires precision, the right materials, and experience. Here's why Twin Cities property owners trust ATR.
More than 25 years of concrete restoration and moisture control across the Twin Cities metro.
ASTM-standard testing with documented results — not guesswork or visual inspection.
We use the same barrier systems specified for hospitals, schools, and commercial buildings.
Most residential projects are tested and mitigated within a week. Minimal disruption.
Common signs include peeling paint or coatings, white mineral deposits (efflorescence) on the surface, damp or musty smell, and flooring adhesive failure. ATR performs quantitative calcium-chloride and relative-humidity testing to give you exact numbers rather than guesses.
A vapor barrier is a membrane installed on or below the concrete slab that blocks moisture vapor from migrating upward. It creates a physical barrier between the water table and your finished floor, protecting adhesives, coatings, and flooring materials from moisture damage.
Testing takes one visit. The barrier installation typically takes 1-2 days depending on the size of the area. Most residential basements are completed in a single day, and you can walk on the surface within hours.
In many cases, yes. If moisture levels exceed manufacturer thresholds, any coating or flooring installed over the slab will eventually fail. Moisture mitigation protects your investment and prevents costly re-dos.
ATR serves the entire Twin Cities metro area including Minneapolis, St. Paul, Bloomington, Eagan, Woodbury, Plymouth, Maple Grove, and surrounding communities. We handle both residential and commercial projects.
Costs depend on the size of the area, severity of moisture, and the mitigation system required. ATR provides free on-site estimates with testing included so you know exactly what you're dealing with before committing.
Don't let hidden moisture destroy your new floors or coatings. ATR provides free moisture testing and professional vapor barrier installation across the Twin Cities.
