| | PART 3 | EXECUTION |
| |
| | 3.1 | EXAMINATION |
| |
| | | A. | Site Verification of Conditions: |
| | | | 1. | Verify that substrate conditions, which have been previously installed under other sections or contracts, are acceptable for product installation in accordance with manufacturer's instructions prior to installation of vapor retarder. |
| |
| | | B. | If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding. |
| |
| | 3.2 | PREPARATION |
| |
| | | A. | Level, tamp and roll the sub-grade soil so that it is well compacted. |
| |
| | | B. | Prepare granular base with sharp crushed rock base course and place over the soil to provide maximum density. |
| |
| | | C. | Ensure that the finished granular sub-base is level, smooth and dense as possible and at the proper elevation. |
| |
| | | D. | Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions. |
| |
| | 3.3 | INSTALLATION |
| |
| | | A. | Follow manufacturer's current installation guidelines, procedures found in the current version of the ACI 302.1R-04, in accordance with ASTM E-1643 and code bodies having jurisdiction. In the event of a conflict in installation requirements, the more stringent method of installation will prevail. |
| |
| | | B. | Unroll vapor retarder over compactable sub-base layer with longest dimension parallel to the direction of the pour. Open folds to full 20 foot (6096mm) width. Ensure that the top layer is always overlapping the bottom layer so that the concrete works its way over the top of the sheets and cannot work its way between adjacent sheets during the pour. |
| |
| | | C. | Overlap seams of vapor retarder a minimum 6 inches (152 mm) and seal with a minimum 4 inch (102 mm) wide tape. |
| |
| | | D. | For below grade floor slab installation, lay vapor retarder over footing, stopping at vertical wall and corner of footing. Seal these terminations with adhesive type waterstop. |
| |
| | | E. | Seal any holes and openings in the vapor retarder. Seal around any penetrations through the vapor retarder, including plumbing systems, piping, and conduit. |
| |
| | 3.4 | PROTECTION |
| |
| | | A. | Protect installed products until completion of project. |
| |
| | | B. | Touch-up, repair or replace damaged products before Substantial Completion. |
