Can concrete be poured in the winter?

Can concrete be poured in the winter? The key is to use the proper sealer or filler depending on the intended purpose and what type of joint it is. Just remember that expansion joints should always be sealed and filled with a flexible joint sealer and never epoxied or coated over.

Do concrete expansion joints need to be sealed? Expansion joints must be sealed with a flexible sealant, like QUIKRETE® Self-Leveling Polyurethane Sealant or QUIKRETE® Non-Sag Polyurethane Sealant…or an expansion joint strip, to prevent water from penetrating the joint and deteriorating the sub-base.

Do I need to fill expansion joints? It might sound like a good idea, but if the joints are filled with a solid material and then covered with epoxy, it defeats their purpose. Improperly filled expansion joints is where the chips and cracks in floors are born. We do not fill the expansion joints; we paint epoxy over them to get the color continuity.

Should you fill driveway expansion joints? Even expansion joints in your concrete driveway should be caulked. They can be the biggest culprit of water under your slabs.

Curing serves these main purposes: It retains moisture in the slab so that the concrete continues to gain strength. It delays drying shrinkage until the concrete is strong enough to resist shrinkage cracking. Properly curing concrete improves strength, durability, water tightness, and wear resistance.
