Material Selection Guide
Which sand and aggregate for which part of your house?
Using the wrong grade causes wall cracks, weak RCC slabs, or wasted money. Here is the standard civil specification for residential construction in Chennai.
| Construction Stage | Recommended Grade | Specification | Why It Matters | Action |
|---|---|---|---|---|
| Roof Slabs, Beams & Columns (RCC) | 20mm Blue Metal (Grade A) & Double-Washed M-Sand | IS 383 Zone II / M20-M25 Grade | Angular blue metal creates high mechanical interlock; double-washed granite sand guarantees zero salt and maximum compressive strength. | Quote → |
| Internal & Ceiling Wall Plastering | P-Sand (Plastering Sand) | IS 1542 Graded (<150 micron controlled) | Super-fine sieved sand with micro-silt removed. Eliminates wall cracks, roughness, and reduces paint primer consumption. | Quote → |
| Brick & Fly Ash Block Masonry | M-Sand (Double Washed) | IS 383 Zone II/III | Consistent grading provides uniform mortar bed thickness and superior bonding with red clay bricks and solid blocks. | Quote → |
| Foundation, Footings & Rafts | 25mm Aggregate & 40mm Gravel (HBG) | 20mm-40mm Hard Broken Granite | Massive load-bearing capacity for column pits and basement floor sub-bases with zero water absorption. | Quote → |
| Compound Roads, Driveways & Paving | WMM (Wet Mix Macadam) & Crusher Dust | MoRTH Specification Graded | Pre-mixed aggregate with controlled moisture compacts into a rock-hard pavement foundation that will not sink under heavy vehicle loads. | Quote → |
