07 19 00 Water Repellents: Common Contradictions and RFI Guide
Waterproofing and water repellent product specs frequently conflict with substrate preparation requirements shown on architectural details.
Most Water Repellents contradictions trace to the same root: the specification and the drawings are produced by different people at different stages, and never fully reconciled before the set goes out. By the time the conflict is found in the field, it is an RFI, a delay, or a change order.
Lintel cross-references section 07 19 00 against your full drawing set, schedules, and the rest of the project manual, flagging every disagreement with a citation to the exact page so it is resolved in review.
Common contradiction types
Product spec vs. substrate prep requirement
A frequent water repellents conflict. Lintel reconciles the drawings against the spec to surface it with a page-level citation, so it is caught in review rather than at rough-in.
Application rate conflicts
A frequent water repellents conflict. Lintel reconciles the drawings against the spec to surface it with a page-level citation, so it is caught in review rather than at rough-in.
Below-grade vs. above-grade product mismatch
A frequent water repellents conflict. Lintel reconciles the drawings against the spec to surface it with a page-level citation, so it is caught in review rather than at rough-in.
Frequent RFIs
- Substrate prep not matching product requirement
- Application rate conflict between spec and product data sheet
- Below-grade waterproofing product not meeting spec
