Anchor company standard · in addition to the 2024 Workmanship Standards
Wet-Area Waterproofing And Flood Test
This is an Anchor requirement for showers, tub surrounds and other wet areas. It adds to, and never replaces, the adopted plumbing and building code, the approved plans and the waterproofing manufacturer's instructions. Where any of those is stricter, the stricter requirement governs.
1. Substrate and slope. The substrate must be sound, clean, flat and approved for the membrane system before waterproofing starts. Shower floors must slope to the drain as required by the adopted plumbing code and the manufacturer system (commonly 1/4" per foot). Record the measured slope.
2. One system, no mixing. Use a complete manufacturer system, or components the manufacturer approves in writing as compatible. Follow the manufacturer's coverage thickness, number of coats, cure times and temperature limits.
3. Continuous membrane. The membrane must be continuous at corners, seams, drain flange, curb, bench, niche and threshold, with no gaps, pinholes or thin spots. Reinforce all changes of plane and seams as the manufacturer requires.
4. Penetrations and fixtures. Seal the valve, shower arm, body sprays, niches, grab-bar blocking and any other penetration with the manufacturer-approved method. Do not rely on grout or caulk alone.
5. Flood test before tile. After the membrane has fully cured, plug the drain and fill the pan to the level required by the code or manufacturer. Mark the water level and photograph it with the date and time. Hold the water for 24 hours, or longer if the building official or manufacturer requires it. Any drop in level is a failure: find the cause, repair, cure and retest.
6. Hold point. Tile, backer finish or any covering must not be installed over the membrane until a passed flood test is recorded. Record the start and end water levels, the date and time, and the initials of the person who verified the test. If the membrane is damaged or the pan is opened after the test, repeat the test.
7. Walls and joints. Use a backer approved for wet areas. Seal seams and fastener penetrations as the manufacturer requires. Use flexible sealant, not grout, at changes of plane and where tile meets a tub, pan, curb or other dissimilar material.
8. Record. Keep photographs of the finished membrane before tile, the flood-test levels at start and end, the product and lot information, and the verifier's initials with the job file.

Code Compliance
Revision 0.3 · Source-currentness recheck: September 30, 2026 · Controlled review checklist
This is a stand-alone code compliance checklist for this trade, added to the workmanship standards above and to full project-code requirements. It is not a complete trade code manual. It covers reviewed 2016–2026 changes and local implementation events; an older provision newly enforced locally is labeled as implementation, not claimed as newly invented code.

PM
Only affected new, replaced or altered work and legally triggered upgrades are included. The PM selects the applicable legal requirement and the compatible mandatory Anchor overlay before work starts. Unresolved source, limit or listing conflicts remain HOLD, and N/A requires a written reason. Checking a box means the item and its required evidence passed, not merely that it was read.
Where a city's legal minimum is lower, the compatible higher check remains an Anchor standard unless Cory approves a company-only exception. A city's nonadoption alone is not a reason to mark the higher company check N/A; actual scope, technical compatibility and legal/design/listing conflicts must be resolved.
Existing QR phases: QR-16A.
WT-01Low-emitting interior ceramic-tile adhesive
Verify the interior ceramic-tile adhesive VOC content limit of 65 g/L under the selected content path, or a documented permitted emission alternative. Submit weight/volume usage so the PM can demonstrate at least 85% compliance in the applicable product category.
- Change / applicability
- 2023 Scottsdale mandatory green-code implementation. Affected: interior-side, site-applied adhesives/sealants under the adopted project green schedule.
- Required record
- Product technical data/certification, correct VOC basis, quantities and approved content-versus-emissions path.
- Hold point
- Before product approval and installation.
WT-02Grout/sealant low-emission category
Verify the 250-g/L content limit or accepted emission alternative, the correct category/VOC basis, and quantities contributing to ≥ 85% category compliance.
- Change / applicability
- Scottsdale 2023 mandatory green-code implementation. Affected: interior architectural sealants, including grout, under the adopted schedule.
- Required record
- Product technical/certification data and weight/volume log.
- Hold point
- Before application.
WT-03Silica exposure controls
Use the fully implemented applicable Table 1 equipment / work-practice / respirator route or an accepted exposure-assessment route. Document a written exposure-control plan and designated competent person when covered, and do not treat short-duration work as automatically exempt.
- Change / applicability
- 2016 federal construction rule; federal enforcement September 23, 2017; Arizona adoption July 23, 2018. Affected: tile/stone cutting, drilling, grinding or other covered silica work. Evaluate exposures from nearby trades as well as your own work.
- Required record
- Task/method, Table 1 entry or exposure assessment, control/respirator evidence, competent person and plan.
- Hold point
- Before dust-producing work.
WT-04Weighed construction-waste diversion
Segregate and document eligible tile, backer, membrane and packaging waste toward the project requirement of at least 50% eligible nonhazardous C&D waste diverted by weight. Exclude excavated soil/land-clearing debris, and do not count alternative daily cover or waste-to-energy as diversion.
- Change / applicability
- 2023 Scottsdale mandatory green-code implementation, not a claim the provision first existed in 2023. Affected: commercial/multifamily green-code scope; resolve the local < 5,000-sq-ft project exception and any higher Anchor requirement.
- Required record
- Weight tickets, material/destination, recycling/reuse receipts and PM project diversion calculation.
- Hold point
- Before trade closeout; keep records throughout work.

Unverified or failed applicable items block the stated hold point. The subcontractor certifies actual work and evidence; the PM independently verifies and releases after required official inspections. Cory approves only company-standard exceptions, never statutory, permit, design or listing waivers.

Applicability Appendix
Record the exact adopted section/amendment, applicable exception, design/product instruction and required test configuration for each item before starting. A model-edition change is not automatically local law, and a local rule exported to another city is an Anchor requirement only when technically compatible and accepted.
This section does not establish an exhaustive all-clause ten-year history or every-city strictness proof. No unverified change is used as a passing criterion; current-only provisions with no demonstrated decade change remain in the full existing acceptance packet rather than falsely appearing here as new changes.
The September 30, 2026 recheck refreshed cited source evidence. A historical source can verify a change without establishing its current local applicability; source recheck is not a project release or a complete clause-by-clause supersession certification.
Silica dates distinguish federal enforcement from Arizona's July 23, 2018 adoption reported by ADOSH. Confirm the currently applicable state-plan standard/amendments before issue; the compatible Anchor safety baseline does not waive them. (Arizona adoption notice)
Scope caution: Existing shower dimensions, liner/flood-test rules and tile workmanship are not labeled decade changes without a verified old-to-new comparison. Retain them in the existing workmanship/code acceptance packet. This caution is not an additional verified decade-change claim.
