elevations of edge restraints around perimeter of area to be paved. Perimeter containment must surround the entire paving area. Contractor and/or Architect/Engineer must verify base is dry, uniform, even and ready to support sand, precast concrete paving units, and imposed loads. Installing the bedding sand and precast concrete paving unit installation constitutes acceptance of base and edge restraint installation. INSTALLATION GENERAL – Pavers on surface of over a 5 degree (or 8.33%) slope requires specific engineering for containment edge support and drainage of the paver system. Installation comply with requirements of applicable building codes and state and local jurisdictions. Spread the bedding sand evenly over the base course and screed to a nominal 1 in. thickness. Do not exceed 1-1/4” thickness. Lay the precast concrete paving units, (NMP), on top of compacted sand in the pattern as defined on the drawings. Maintain straight pattern lines. Use low amplitude, high frequency plate vibrator to compact the Narrow Modular pavers into sand bed. Provide separation layer between hard plate of vibrator and paver surface to avoid damaging paver surface, for example plywood sheets, (7/16” min thickness), to protect against surface scratching and evenly distribute the impact load during compaction. Pass vibrator across the short dimension of the paving units. Typical joints between the pavers at the top of paving surface shall be roughly 3/16” to 1/4” wide. Refer to Section 2.4.C for standard dimensional paver tolerances. (Note: Recommended minimum spacing at bottom of pavers is 1/16”.”) Fill gaps at edges of the paved area with cut precast concrete paving units Fill joints with sand. Note to specifier: Select one of the following joint sand options Joint sand to meet specifications ASTM C 144 mixed with joint sand stabilizer per
