Edge Form

Definition

A forming member used to limit the horizontal spread of fresh concrete on flat surfaces.

Purpose

Edge forms are essential in concrete construction for creating clean, defined edges and controlling the flow of concrete. They help ensure that the concrete remains within the designated area, resulting in precise and uniform edges on flat surfaces such as floors, slabs, and pavements.

Examples of Use

• Using edge forms to shape and contain concrete for a new sidewalk or driveway.
• Creating sharp, clean edges for a concrete patio or floor slab.
• Forming the perimeter of a concrete foundation to maintain the desired shape and dimensions.

Related Terms

• Formwork: Temporary or permanent molds used to shape and support wet concrete until it hardens.
• Screed: A tool used to level and smooth freshly poured concrete.
• Rebar: Reinforcing bars embedded in concrete to increase its strength.

Notes

• Proper installation and bracing of edge forms are crucial to prevent movement and ensure accurate concrete placement.
• Edge forms can be made from various materials, including wood, metal, and plastic, depending on the project requirements.
