Penetration Rectification
A failed penetration is not fixed by covering the defect. The rectification has to restore a supported system for the actual condition.
Overview
FRS reviews penetration defects from inspections, handover lists, audits and existing-building surveys. We separate the visible defect from the evidence problem, then work out whether the installed condition can be corrected, needs further technical review, or should be removed and rebuilt to a supported detail.
Common reasons a penetration is rejected
- Wrong or unverified product for the actual service and substrate combination.
- Opening size or annular space outside what the test report covers.
- A service added after the original installation.
- Mixed services where the test evidence covers only a different arrangement.
- Missing, incomplete or damaged fire-stopping material.
- Incorrect depth, backing, collar, wrap, batt or fixing arrangement.
- Insulation or sleeve condition not matching the tested detail.
- Wall or floor construction different from the detail used.
- Unlabelled or undocumented penetration with no traceable system record.
- Poor workmanship, damaged substrate, or an opening that has changed since handover.
How we approach it
We start from the defect report, schedule or site condition you already have. We identify the separating element, the service configuration and the required project outcome, then find the evidence for the installed system — or identify the gap where it cannot be established. From there we decide whether the existing system can be brought back inside a supported arrangement. If it cannot, we define a replacement detail and move any unsupported variation into the right technical review path, rather than closing it out quietly.
We fix the reason it was rejected
Anyone can add sealant until an opening looks finished. A neat surface still sits over the wrong service combination, the wrong substrate, the wrong depth or a system with nothing behind it — and it fails the same audit next time. We go back to why the penetration was rejected and close that out, so the item stays closed.
Large defect lists
If you have hundreds of penetration defects, send the existing report or register. We group like conditions, separate repeatable fixes from exceptions, and build a staged scope — rather than treating every line as a separate mystery.
Questions
Frequently asked questions
- Can you repair penetrations installed by another contractor?
- Yes — a lot of our rectification work is somebody else's installation. We identify what is actually there, rectify it to a system that holds up, and record it against the location so it does not come back at the next audit.
- Do you need to inspect every defect before pricing?
- Not always. A good defect register, penetration schedule and photo set can support a first-pass scope. Site verification is still needed where the records do not establish the actual condition.
- Can an engineering assessment fix an installation that does not match the tested detail?
- Sometimes. An assessment is not a generic permission slip, but where the variation is genuine we assemble the evidence and run it with the assessor so you get a supported answer rather than a rebuild.
- What if the wall has changed or the opening is damaged?
- The wall or floor is part of the system, so we repair that too. Reinstating the seal on damaged construction leaves the defect live, and we would rather quote the real scope than close out something that has not been fixed.
