These restraints prevent pavers from shifting or spreading, maintaining their intended pattern and preventing damage. This guide provides a comprehensive overview of paver installation edge restraints, covering their types, materials, installation methods, and best practices.
Types of Paver Installation Edge Restraints
Flexible Edge Restraints
- Plastic Edging: Made of durable plastic, these restraints are flexible and easy to install. They are ideal for curved or irregular edges.
- Rubber Edging: Similar to plastic edging, rubber edging is flexible and provides a more natural appearance.
- Geotextile Fabric: A permeable fabric that prevents soil erosion and weed growth, geotextile fabric can be used as an edge restraint for pavers.
Rigid Edge Restraints
- Concrete Curbing: A permanent and durable option, concrete curbing is poured into a mold and cured to create a strong and stable edge.
- Metal Edging: Available in various metals such as steel, aluminum, or corten steel, metal edging provides a sleek and modern look.
- Stone Edging: Natural or manufactured stone edging adds an elegant and timeless touch to paver installations.
Materials for Paver Installation Edge Restraints
Plastic
- Polyethylene: A lightweight and durable plastic, polyethylene is commonly used for flexible edge restraints.
- Polypropylene: A stronger and more rigid plastic, polypropylene is suitable for both flexible and rigid edge restraints.
Rubber
- Recycled Rubber: Made from recycled tires, recycled rubber edging is environmentally friendly and provides excellent durability.
- Virgin Rubber: A more expensive option, virgin rubber edging offers superior strength and longevity.
Metal
- Steel: A strong and durable metal, steel edging is available in various thicknesses and finishes.
- Aluminum: A lightweight and corrosion-resistant metal, aluminum edging is ideal for areas with high moisture.
- Corten Steel: A weather-resistant steel that develops a protective patina over time, corten steel edging adds a unique aesthetic appeal.
Stone
- Natural Stone: Granite, limestone, and sandstone are popular natural stone options for edge restraints, offering durability and a natural look.
- Manufactured Stone: Concrete or porcelain pavers can be used as edge restraints, providing a cohesive appearance with the paver surface.
Installation Methods for Paver Installation Edge Restraints
Flexible Edge Restraints
- Dig a trench along the edge of the paver area.
- Place the edge restraint in the trench and backfill with compacted soil.
- Secure the edge restraint with stakes or pins.
Rigid Edge Restraints
- Excavate a trench and pour a concrete base.
- Install the edge restraint on the concrete base.
