Extra coats, extra areas, missing from the invoice.
Waterproofing scope grows in the field — substrate conditions change, membrane specs get upgraded, and additional areas get added on the GC's verbal say-so. Every addition not captured at the moment it happens is a line item you'll struggle to justify at billing time. Revecta captures it while it's happening.
What typically falls off the invoice
Waterproofing revenue leakage almost always starts as a verbal upgrade or an additional area — small enough that the foreman thinks it's covered, large enough that it shows up as a real cost at the end of the job.
- ▸Additional surface prep ordered after moisture readings came back elevated
- ▸Extra membrane application areas added when adjacent surfaces failed inspection
- ▸Material upgrades the GC directed verbally after the original scope was priced
- ▸Return trips when work area wasn't ready on the original schedule
- ▸Additional detailing at penetrations or transitions found during install
- ▸Standby time while substrate repairs by other trades were completed
How Revecta works for waterproofing crews
Field-first capture — scope additions logged on site, not rebuilt from memory at the end of the month.
Capture additional scope at the point of direction
When a GC upgrades the membrane, adds a drainage course, or extends the scope area verbally, the foreman logs it immediately — with the area, material, and who directed it. Not reconstructed at billing.
Document surface conditions and prep work with photos
Before-and-after photos attached to field events provide the substrate documentation GCs need to understand why additional scope was required — and to approve it confidently.
Compile a Proof-of-Work document for GC review
All captured field work rolls up into one auditable document — what was done, where, and when. The GC reviews and approves via a secure link, no account required.
Revenue Recovery Engine flags unbilled work
Revecta scans documented field events for work that is captured but not yet priced, submitted, or invoiced — surfaced before it falls off the invoice entirely.
Built for waterproofing field workflows
Substrate documentation, material quantities, application areas, and field-directed scope additions — captured in the field and compiled into a GC-ready proof document. Not a generic construction form.
Where waterproofing scope changes most often
Substrate conditions drive most waterproofing scope changes — and substrate conditions aren't known until the crew is on site. These are the scenarios where verbal directives most often generate unbilled work.
Elevated moisture readings
When a substrate tests wetter than spec, additional drying time, primer coats, or moisture-mitigation products are added verbally. That additional scope needs to be documented before the next coat goes on.
Membrane spec upgrades
An architect or GC upgrades the membrane system after the original scope was priced — thicker membrane, additional plies, or a higher-rated product. The material delta and reinstall labor belong on a change order.
Adjacent surface failures
During installation, adjacent areas that weren't in the original scope show visible cracks or substrate failures. The GC directs coverage extension verbally on the spot.
Transition and penetration detailing
Pipe penetrations, drains, and wall-to-floor transitions often require additional detailing not in the original drawings. This work is directed in the field and almost never put in writing.
Return trips for substrate prep
When the original schedule required other trades to complete substrate repairs first, return mobilization is an additional cost that must be documented to bill.
Drainage and protection board additions
Protection boards or drainage composites added after the waterproofing membrane is installed add both material and labor. Verbal directive at the time of installation is the only record unless captured immediately.
Why substrate documentation matters at billing time
Waterproofing disputes almost always come down to one question: was the additional work actually necessary, or did you just do more than you were asked? The answer to that question lives in the substrate conditions at the time of installation — moisture readings, crack surveys, prior coating condition — not in a conversation weeks later.
A photo of a moisture meter reading against the slab, taken at the point of diagnosis, is a stronger basis for an additional-coat charge than any field note. A photo of the crack pattern that justified additional detailing, timestamped before the membrane was applied, answers the GC's question before they ask it.
Revecta is built for this workflow: attach photos to a field event at the moment the condition is found, log what was directed and by whom, and compile it into a Proof-of-Work document before moving to the next area. The documentation happens as part of the field workflow — not as a separate office task after the job is done.
Frequently asked questions
How does Revecta handle waterproofing T&M scope additions?
Field crews log additional surface prep, extra material applications, and scope additions as they happen — what was done, where, by whom, and when. Each field event is timestamped and can include photos. That record becomes a Proof-of-Work document the GC reviews and approves via a secure link.
What if the GC upgrades the membrane spec on site?
That's a verbal directive that generates real cost — labor for removal and reinstall, plus the material delta. Revecta captures it as a field event at the moment of direction so it appears in the billing record rather than being argued at invoice time.
Does Revecta track material quantities used per area?
Yes — field logs can include material quantities per application area. That supports both your material cost tracking and the backup documentation GCs need to approve an invoice for extra scope.
Can Revecta work alongside Procore or other GC platforms?
Yes. Revecta is a field-capture and billing-proof layer for your side of the job — it doesn't require the GC to change any of their systems. Your crew captures work, Revecta builds the proof, and the GC approves it without creating an account.
