The purpose of an expansion joint is to allow the concrete slab to expand and contract with temperatures changes, without cracking the slab. Expansion joints must be sealed with a flexible sealant, like QUIKRETE® Self-Leveling Polyurethane Sealant or QUIKRETE® Non-Sag Polyurethane Sealantor an expansion joint strip, to prevent water from penetrating the joint and deteriorating the sub-base.
Read MoreFor stamped concrete, if the pattern has straight lines, such as slate, brick, or wood patterns, cut your joints to follow the stamped pattern as much as possible. Joints can vary in location a few inches or even a foot or two without leading to cracks. Some stamping contractors use custom-fabricated chisels to cut joints into the stamped

Sealing cracks on concrete floors allows to strengthen the screed and protect it from mechanical chips at the joints, prevents tears, punctures, and abrasion. This is especially important if you plan to put a ceramic tile on the concrete floor, as with leaky joints in the coating, cracks appear, which leads to rapid destruction of the tile coating.

2000-9-1 Water reaching poorly sealed joints will bypass the flashing. During many rainstorms, especially wind-driven rains, some water will build up in the cavities. This will depend on the amount of water penetration, the velocity of the wind, the air-pressure differential across the masonry, and the effectiveness of the weep holes.
