To control seasonal thermal and shrinkage cracking in lengthy exposed slabs, which planning approach spaces engineered movement joints responsibly?
Choices
- (A) Use monolithic pours regardless of climate swings
- (B) Provide engineer-stamped joint layouts tying thermal and shrinkage movement to support restraints
- (C) Ignore axial expansion because finishes hide cracks
- (D) Rely on decorative trims without structural jointing
Correct answer: (B)
Provide engineer-stamped joint layouts tying thermal and shrinkage movement to support restraints
Explanation
Joint spacing links thermal/shrinkage strain to boundary restraint conditions.
