Lay your stone the smart way
Discuss layout, joints and slab inspection with DesignAI — it summarises your floor, stone and slab count to cut wastage and get a clean finish.
Estimate only. Natural-stone slab sizes vary slab-to-slab and quarry-to-quarry — confirm actual gangsaw sizes with your vendor. Wastage depends heavily on room shape, slab defects and laying pattern, so a busy or L-shaped layout may need more than the default 15%. Always inspect full slabs in daylight for cracks, resin fills and shade variation, and buy 1–2 spare slabs from the same lot. Rates are indicative midpoints for India 2026 and exclude adhesive, laying labour, skirting, polishing and transport.
