Why Do They Put Lines in Concrete?

These joints are called expansion or control joints and are designed to make sure as the soil shifts or moves under varying seasons, the slab will not crack along the large flat portions. Many don’t know that these expansion joints vary in design.

Concrete is one of the most widely used materials in construction and is often seen in roadways, driveways, sidewalks, and other areas. It is a durable material that provides a strong foundation for buildings and other structures. But what most people don’t realize is that there are lines in concrete, and these lines have a purpose.

First, let’s discuss what lines in concrete are. Lines in concrete are typically made of steel or other metal materials and are placed in the concrete to help control and guide the spread of the concrete when it is poured into place. These lines are also known as control joints and are typically 1/4 to 3/4 inch in width.

The purpose of lines in concrete is to help reduce stress in the slab. When concrete is poured and dries, it will shrink slightly, and this shrinkage can cause the concrete to crack. The lines in the concrete will serve as a break in the concrete, allowing it to crack in a controlled manner. This reduces the risk of concrete cracking in an uncontrolled manner, which can cause structural damage.

Lines in concrete can also be used to help create a desired pattern or design in the concrete. For example, lines can be spaced apart and used to
