Movement Joints

Expansion Joint Calculator

Plan the field movement joints for a tiled or stone floor. Enter the room, its exposure and tile type — get the joint grid, total linear metres and the perimeter gap, so big tiles don't tent or pop. Indicative India 2026; follow IS 15622 & your adhesive maker's detail.

Your floor

Floor is 30 sq m. At interior — shaded, no bay should exceed about 8 m. Stable indoor floor away from direct sun. Field joints up to ~8 m apart. Perimeter gap is clamped to 5–20 mm and kept hidden under skirting. Always confirm against IS 15622 and your adhesive maker.

Plan view: orange lines are field joints; the dashed edge is the perimeter gap. Largest bay ≈ 6 × 5 m.

Field-joint vs perimeter-gap linear metres. Indicative — verify IS 15622 / manufacturer.

This floor is small enough to need perimeter movement joints only — keep the perimeter gap under skirting and add joints at every doorway. No interior field joints required at this spacing.

Indicative planning aid only. Movement-joint spacing depends on tile size, substrate, climate and adhesive — always follow IS 15622, tile-council practice and your adhesive manufacturer's instructions, and have a site engineer confirm joint positions before laying.
