Concrete slab moisture mitigationConcrete slab moisture mitigation rough-in inspection checklist
Concrete slab moisture mitigation rough-in is the last time the work is fully visible. Once the cover inspection passes and the walls, ceilings and slabs close, every defect left behind becomes a demolition bill. This checklist walks the rough-in in the order the work goes in, with the photo each item needs before it gets buried. Work is commonly verified against manufacturer's published instructions, ASTM F3010 / F710 guidance. Confirm the edition your authority having jurisdiction has adopted.

Who runs it
The mitigation applicator's lead confirming the slab is ready, or the GC's superintendent releasing the slab before the coat starts.
When in the schedule
After the slab is tested and prepped and before the first mitigation coat, while a wrong system pick or a missed crack can still be caught.
The checklist
Every item, and the photo that proves it
The photo count on each row is what RTI would require before the item can be submitted. Copy the list as is, or load it into RTI and let the gate enforce it.
Moisture and system selection
- 2 photos
Slab moisture or RH result drives the system
Current in-situ RH or moisture reading on record, the mitigation system selected matching that result and the flooring to go over it, not an assumed value.
- 1 photo
Slab clean, dry and free of bond-breakers
No curing compound, sealer, adhesive residue or dust left on the surface that would stop the coat from bonding to the concrete.
Surface preparation
- 2 photos
Profile achieved across the whole slab
Prep taken to the profile the system calls for over the full area including edges and corners, verified against the reference, not just in the open field.
- 2 photos
Cracks and joints treated before the coat
Moving cracks and control joints filled or detailed per the system rather than coated over, treatment carried into the joint as specified.
What usually sends this back
The failures are almost always the evidence, not the work
- System chosen off an old moisture number so the coat is rated below what the slab is actually giving off, and it fails under the flooring.
- Slab shot-blasted in the field but left with laitance or a curing compound in the corners the machine could not reach, so the coat never bonds there.
- Active cracks and control joints skimmed with the coat as if they were part of the field, so they telegraph and split the membrane.
Run it with the Photo Gate
A checklist nobody can submit half-finished
Load this list into RTI, stick a QR tag on the area it covers, and the submit button stays locked until every mandatory item is answered and the 7 required photos exist. Approved walks roll into a branded turnover package with a tamper-evident record behind every line.
Submission state
The gate is enforced on the server, so it holds even if the phone is offline when the walk happens.

Common questions
- What does this concrete slab moisture mitigation rough-in checklist cover?
- 4 items across 2 sections, covering moisture and system selection, surface preparation. 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 mitigation applicator's lead confirming the slab is ready, or the GC's superintendent releasing the slab before the coat starts.
- When in the schedule should this walk happen?
- After the slab is tested and prepped and before the first mitigation coat, while a wrong system pick or a missed crack can still be caught.
- Why does every item ask for a photo?
- 7 of the 4 items call for photo evidence. 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 rough-in inspection?
- System chosen off an old moisture number so the coat is rated below what the slab is actually giving off, and it fails under the flooring. Slab shot-blasted in the field but left with laitance or a curing compound in the corners the machine could not reach, so the coat never bonds there. Active cracks and control joints skimmed with the coat as if they were part of the field, so they telegraph and split the membrane.
- 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.
