VSI M-Sand (Vertical Shaft Impactor M-Sand), also known as Robo Sand in South India, is manufactured using the VSI crushing technology which produces particles with a rounder, more cubical shape compared to conventional jaw-crushed M-Sand. This superior particle shape significantly improves concrete and plaster workability, reduces water demand, and results in better packing density. VSI M-Sand is the premium grade of manufactured sand — the preferred choice for high-grade concrete and high-quality plaster finishes.
Available in bulk supply across Chennai, Chengalpattu, Kanchipuram, Thiruvallur, and all of Tamil Nadu. Delivered directly to your construction site in 24–48 hours. GST invoice provided on every order.
