The durability of your home depends on the quality of its structural DNA. Explore our complete material specifications sheet: Fe550D primary steel, machine-batched M25 concrete, Dr. Fixit waterproofing, and Kajaria vitrified ceramics.
Key Takeaways & Executive Summary
- Demand primary mill Fe550 or Fe550D TMT rebar (Tata Tiscon, Jindal Panther, SAIL) with high elongation properties for seismic safety.
- Use 43 Grade PPC cement for brick masonry and plastering, and high-strength 53 Grade OPC cement for structural column-beam casting.
- Never compromise on sand quality: require double-washed coarse riverbed sand free from organic silt and clay contamination.
- Gupta’s Evergreen Developers LLP maintains manufacturer mill test certificates and third-party laboratory test logs for every batch.
1. Primary Structural Civil Materials Schedule
In Uttarakhand’s Seismic Zone IV, material specifications are a matter of life safety, not cosmetic preference. Sub-standard re-rolled steel from secondary scrap mills exhibits brittle failure during earthquake tremors.
Here are the mandatory structural material standards enforced on all Gupta’s Evergreen Developers LLP construction sites:
| Material Category | Approved Primary Brands | Grade / Specification | Relevant Indian Standard (BIS) |
|---|---|---|---|
| Structural TMT Rebar | Tata Tiscon, Jindal Panther, SAIL | Fe550D High Ductility with 0% Surface Rust | IS 1786 (High Strength Deformed Bars) |
| Structural Cement | Ultratech, ACC, Ambuja | 53 Grade OPC (Structure) / PPC (Masonry) | IS 12269 (53 Grade) & IS 1489 (PPC) |
| Coarse Concrete Aggregates | Local Blue Granite Crushed Stone | 20mm & 10mm Graded, Angular Shape | IS 383 (Coarse and Fine Aggregates) |
| Fine Masonry Sand | Doon Valley Washed Riverbed Sand | Zone II Coarse Sand, Silt Content < 4% | IS 383 Testing Guidelines |
| Waterproofing Systems | Dr. Fixit, Fosroc, Sika | 3-Coat Polymer Modified Elastomeric Slurry | IS 3067 (Code of Practice for Waterproofing) |
| Sanitary & Water Supply | Astral, Supreme, Ashirvad | CPVC SDR 11 (Hot/Cold) & SWR PVC for Drainage | IS 15778 (CPVC) & IS 13592 (SWR) |
2. Finishing & Architectural Joinery Schedule
Finishing materials define everyday luxury, thermal acoustic comfort, and long-term aesthetic beauty:
- Flooring & Dado: Kajaria or Somany 4x2 foot double-charged glazed vitrified tiles in bedrooms; imported polished Italian Statuario marble in grand salons.
- Windows & Glazing: 3-track multi-chamber UPVC profiles (Fenesta / Aluplast) with SS mosquito mesh and 5mm+12A+5mm toughened acoustic double glazing.
- Paint & Exterior Coats: Two coats of Asian Paints Apex Ultima exterior weather-defense emulsion; Asian Paints Royale Luxury interior emulsion on putty base.
- Electrical Wiring: Concealed FRLS (Flame Retardant Low Smoke) copper stranded wires from Havells or Finolex with Legrand modular switches.
