Expansion joint systemsExpansion joint systems rough-in inspection checklist
Expansion joint systems 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, the applicable building code. Confirm the edition your authority having jurisdiction has adopted.

Who runs it
The joint-system installer with the GC's superintendent, releasing the prepared joint before the cover assembly goes on.
When in the schedule
After the blockout is formed and any nosing and anchors are set, before the cover assembly and adjacent finishes close over the joint.
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.
Blockout and nosing
- 2 photos
Blockout width and nosing correct for the rated movement
Gap measured against the system's movement range at the current temperature, nosing formed square and to the right depth for the cover.
- 2 photos
Substrate and anchors sound at the joint edges
Edge concrete solid and clean, anchors set to the specified pattern and embedment, no crumbling or featheredged nosing.
Barrier continuity
- 2 photos
Fire barrier continuous through the joint
Fire barrier packed continuous along the joint and carried through changes of plane, no gaps where the floor joint turns up a wall.
- 2 photos
Water barrier continuous at the joint
Waterproofing or membrane lapped into the joint and continuous at transitions, drainage path maintained where the system sheds water.
What usually sends this back
The failures are almost always the evidence, not the work
- Blockout formed to a nominal width without accounting for the gap at the temperature the concrete was placed, so the system can't take its rated movement.
- The fire barrier at the joint stopped short at a change of plane, leaving an unsealed gap where the floor joint turns up the wall.
- Nosing anchors set into weak edge concrete that spalls the first time the cover is loaded, pulling the assembly loose.
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 8 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.

- 4 items across 2 sections, covering blockout and nosing, barrier continuity. 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 joint-system installer with the GC's superintendent, releasing the prepared joint before the cover assembly goes on.
- When in the schedule should this walk happen?
- After the blockout is formed and any nosing and anchors are set, before the cover assembly and adjacent finishes close over the joint.
- Why does every item ask for a photo?
- 8 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 expansion joint systems rough-in inspection?
- Blockout formed to a nominal width without accounting for the gap at the temperature the concrete was placed, so the system can't take its rated movement. The fire barrier at the joint stopped short at a change of plane, leaving an unsealed gap where the floor joint turns up the wall. Nosing anchors set into weak edge concrete that spalls the first time the cover is loaded, pulling the assembly loose.
- 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.
