WHAT ARE CONTROL JOINTS?

It is important to be active in deciding where control joints are placed. Don't leave this important part of concrete construction to chance.

Make sure you are cutting joints soon enough. In hot weather, concrete might crack if joints are not cut within 6-12 hours after finishing concrete. In this condition, if you don't want to use a grooving tool to cut joints, there are early-entry dry-cut lightweight saws that can be used almost immediately after finishing.

V shape, T shape segments or customize sepecial blades are available now.
