Construction Joints - an interruption of the concrete pour 30 minutes or greater creates a construction joint.
Expansion Joints - Designed to negate the compressive forces from abutting concrete structures that may occur as a result of expansion, loads, or differential movement from settlement. Expansion joints require an actual gap between the concrete pours, which is frequently filled with a compressible joint filler material such as foam, rubber, cork, or cane fiber board.
