TL;DR
A tooled joint is a straight groove pressed into fresh concrete with a grooving tool to create a deliberately weakened plane where shrinkage cracking will occur, hidden inside the joint instead of wandering across the slab. Effective grooves reach about a quarter of slab depth, so a 4-inch sidewalk needs a 1-inch-deep joint, spaced in feet at roughly two to three times the thickness in inches.
What it means
A tooled joint is a straight groove pressed into fresh concrete with a grooving tool to create a deliberately weakened plane where shrinkage cracking will occur, hidden inside the joint instead of wandering across the slab. Effective grooves reach about a quarter of slab depth, so a 4-inch sidewalk needs a 1-inch-deep joint, spaced in feet at roughly two to three times the thickness in inches. The rounded, burnished edges also resist chipping, which is why finishers tool rather than saw most residential flatwork.
