## 5. Container Logistics, Packing Specs & Freight Calculation
Natural stone is heavy dimensional cargo governed by maritime container gross weight constraints:

- **20GP Dry Container Max Payload:** Approx. 26,000 kg – 27,000 kg depending on shipping line route limits.
- **20mm Thickness Pavers:** ~52 kg/m² → One 20GP container carries approx. **480 m² to 520 m²** (approx. 20–22 wooden crates).
- **30mm Thickness Pavers:** ~78 kg/m² → One 20GP container carries approx. **320 m² to 340 m²** (approx. 18–20 wooden crates).
- **Fumigation & Timber Crates:** Heat-treated (ISPM 15 compliant) hardwood timber crates reinforced with steel strapping, lined with waterproof polyethylene film, and cushioned with high-density EPE foam corner protectors.

## 6. Sub-Base Installation & Chemical Sealing Protocol
1. **Sub-Base Requirements:**
   - Minimum 100mm reinforced concrete slab with 1:100 slope away from buildings for outdoor vehicular/patio applications.
   - Or compacted crushed aggregate base (150mm) with permeable open-graded bedding for water-permeable pedestrian installations.
2. **Mortar & Adhesives:**
   - Use high-polymer modified stone adhesive (C2S1 or C2S2 grade per EN 12004) with 100% back-buttering coverage to eliminate moisture voids under pavers.
3. **Penetrating Sealer Application:**
   - Never apply topical polyurethane or acrylic clear coats on outdoor limestone (they trap subterranean moisture, leading to efflorescence and spalling).
   - Apply high-grade penetrating fluoropolymer or silane/siloxane impregnating sealer (e.g. Dry-Treat Stain-Proof or Lithofin MN Stain-Stop) 14 days post-grouting once all joint moisture has fully evaporated.
   - Re-application cycle: Every 3–5 years for exterior patios; every 2 years for salt-chlorinated swimming pool borders.
