Dummy Joint

Definition

A joint placed strictly for design in sidewalks and patios.

Purpose

Dummy joints are used to create visual divisions and control the appearance of concrete surfaces. They are not intended to accommodate movement or stress but to enhance the aesthetic appeal of the pavement.

Examples of Use

1. Sidewalks: Used to create a uniform appearance and simulate the look of smaller sections.
2. Patios: Adds visual interest and defines different areas within the patio surface.
3. Driveways: Used to create decorative patterns and control the layout of concrete surfaces.

Related Terms

• Control Joint: A joint designed to control cracking in concrete by allowing for movement due to shrinkage and temperature changes.
• Expansion Joint: A joint that allows for expansion and contraction of concrete structures due to temperature variations.
• Score Line: A shallow groove in concrete to create a visual break or pattern.

Notes

• Dummy joints are typically shallow and do not affect the structural integrity of the concrete.
• They are often used in conjunction with other types of joints to achieve both functional and aesthetic goals.
