What does this concrete slab moisture mitigation final checklist cover?

14 items across 4 sections, covering coverage and thickness, continuity and tie-in, verification, protection and records. Each item spells out what the person walking the job is actually looking for, not just a box to tick.

Who should run this inspection?

The GC's superintendent with the applicator, walking the coated slab before flooring is released over it.

When in the schedule should this walk happen?

After the mitigation coat has cured and before any flooring or adhesive goes down, since the membrane is buried and unreachable after that.

Why do these items ask for a photo?

9 of the 14 items call for photo evidence, 12 photos in all. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.

What most often fails a concrete slab moisture mitigation final inspection?

Coat spread thin to stretch the kit so consumption comes up short of the rate the system needs to hold back the vapor. Pinholes and thin spots left uncoated because a second coat was skipped, giving vapor a path straight through the holidays. Flooring released the same day with no retest or bond check, so nobody confirmed the membrane actually did its job before it was covered.

Can I use this checklist in RTI?

Yes. Start a free RTI workspace, build this list as a checklist, and the Photo Gate holds the submit button until every mandatory item is answered and its photos are attached. Approved inspections roll into a branded turnover package with a tamper evident audit trail.

Concrete slab moisture mitigation final inspection checklist

Concrete slab moisture mitigation final inspection is where the punch list is either short or expensive. This checklist walks the finished work the way an owner or AHJ will see it: devices on, systems running, everything labeled. Each item gets the photo that closes it instead of reopening it. Work is commonly verified against manufacturer's published instructions, ASTM F3010 / F710 guidance. Confirm the edition your authority having jurisdiction has adopted.

The checklist

Every item, and the photo evidence it needs

The photo count on each row is what RTI would require before the item can be submitted. Work the list here and watch the gate hold, or load it into RTI and let it enforce the real thing.

Coverage and thickness

Consumption and thickness meet the required rate
Material used compared against the coverage rate for the area, wet or dry film thickness checked, no areas stretched thin to make the kit last.
Cure taken before anything goes over it
Coat given its cure time and conditions per the system before recoat or flooring, surface hard and not tacky or soft underfoot.
Recoat and next-layer timing inside the system's window
Coat dates checked against the recoat and overcoat window the manufacturer lists; a missed window abraded or reprimed per the instructions before the next layer.
No photo
Cured surface free of blush, dust and oil film
Coat wiped and looked at for a waxy or greasy blush, tracked-in dust and footprints, cleaned per the system before any primer, topping or adhesive goes on.
Top of the system matches what the flooring adhesive needs
Primer, sand broadcast or cementitious layer over the membrane in place as the mitigation and flooring instructions require, so adhesive bonds to the tested surface.
No photo

Continuity and tie-in

Continuous film with no holidays
Coat unbroken across the field under raking light, no pinholes, skips or thin translucent spots, second coat where the system requires one.
Edges, penetrations and terminations tied in
Coat carried up at walls, columns and penetrations and terminated as detailed, no gap at the perimeter where vapor could bypass the membrane.
Crack and joint details intact in the cured coat
Each crack and joint on the map shows the treatment the system calls for, with no split, ridge or open line through the film above it.
Coat walked and tapped for blisters and soft spots
Field walked and sounded for blisters, outgassing craters, lifted edges and soft areas; each one marked on the plan for repair before flooring.

Verification

Retest or bond check before flooring is released
The system's confirmation step performed on the cured coat and the result on record before flooring is scheduled over the slab.
Every zone on the test map coated to its limits
Each room and zone the moisture report put in the mitigation scope walked and found coated, the edge of the coat matching the limits on the plan.
No photo

Protection and records

Cured coat protected from carts, lifts and stored material
Protection board or a no-staging zone kept over the membrane until flooring starts, with any new scuff or cut marked for the applicator.
Applicator's log with batches, kits and conditions on file
Log lists the areas coated, coat dates, batch numbers, kits used and the temperatures read, filed for the warranty and the closeout record.
No photo
Mitigation warranty registration filed with its records
Warranty paperwork the mitigation manufacturer requires sent in with the moisture report, product data and application log, and a copy kept for turnover.
No photo

What usually sends this back

The failures are almost always the evidence, not the work

Coat spread thin to stretch the kit so consumption comes up short of the rate the system needs to hold back the vapor.
Pinholes and thin spots left uncoated because a second coat was skipped, giving vapor a path straight through the holidays.
Flooring released the same day with no retest or bond check, so nobody confirmed the membrane actually did its job before it was covered.

Verified against

ASTM F710 / F3010 (slab moisture)
