Various types of edge restraints are available, each suited for specific materials and conditions. Here are some common types:
Rigid Plastic or PVC: These are popular for their ease of installation. They are often used in walkways and patios.
Aluminum: Known for their strength and durability. Aluminum restraints are typically used in driveways and other high-traffic areas.
Concrete or Stone: These provide a natural look and are often used with similarly natural pavers. They are ideal for garden paths and decorative landscapes.
Metal Edging: Offers a sturdy option that can withstand heavy loads. It’s frequently used in commercial spaces.
Each type has its unique advantages, and choosing the right one depends on the specific needs of the project.
Concrete Paver Edge Restraints
Concrete paver edge restraints come in two main types: preformed concrete options and poured concrete methods. Each type offers specific benefits and considerations.
Preformed Concrete Options
Preformed concrete edge restraints are pre-cast units designed to provide a durable and stable edge for pavers.
These are usually created in standard shapes and sizes, which makes them easy to install. Preformed options often lock the pavers in place, reducing movement. They are especially suited for areas with heavy traffic, as they provide a strong border.
Installation involves placing the preformed units along the edge of the paver base and securing them with spikes or adhesive. This method ensures uniformity and precision. These options are available in various colors and textures, allowing them to match the pavers and the surrounding landscape.
Advantages include their ease of installation and consistent quality, as they are made in controlled conditions. They are also less likely to crack due to uniform mixing and curing processes.
Poured Concrete Methods
Poured concrete edge restraints are custom-made on-site, providing flexibility in design and shape.
This method involves pouring concrete along the edge of the pavers to form a continuous, strong barrier. It is highly adaptable, allowing for smooth curves and custom designs that match the layout of the paver area.
Installation requires proper preparation, such as setting up forms to shape the concrete. Once the forms are in place, concrete is mixed and poured, then finished to the desired shape and texture.
Advantages include a seamless appearance and enhanced strength. Poured concrete is less likely to shift over time, providing a long-lasting solution.
Brick Paver Edge Restraints
Brick paver edge restraints are crucial for keeping the pavers in place and maintaining the integrity of the design. Two common types are metal edging and plastic edge restraints. Each has its own benefits and drawbacks.
Metal Edging
Metal edging provides a sturdy and durable option for brick pavers. It is often made of aluminum or steel. Aluminum edging is lightweight and resistant to rust, making it a long-lasting choice.
Steel edging, on the other hand, offers exceptional strength and can hold heavy loads. Metal edging can be installed with minimal tools; usually, stakes are driven into the ground to secure it.
The main advantage of metal edging is its durability. It is less likely to shift over time, ensuring that the pavers remain in place. However, metal edging can be more expensive compared to plastic options.
Pros:
- Strong and durable
- Resistant to weather
- Holds heavy loads
Cons:
- Higher cost
- Requires proper installation
Plastic Edge Restraints
Plastic edge restraints are another popular choice for brick pavers. These are typically made from polyethylene or PVC. Polyethylene is flexible and easy to handle, making it a good option for curved designs. PVC provides more rigidity and is often used for straight edges.
Installation of plastic edge restraints is straightforward. They can be cut to size with basic tools and are usually secured with spikes driven into the ground.
Pros:

- Easy to install
- Cost-effective
Cons:
- Less durable than metal
- May shift over time
Plastic edge restraints are practical for lighter loads and simpler projects. They offer a balance between cost and functionality, making them a preferred choice for many DIY homeowners.
Natural Stone Paver Edge Restraints
Natural stone paver edge restraints can be either mortar-based or use flexible edging solutions. Both methods have their own benefits and are suited for specific needs.
Mortar-Based Restraints
Mortar-based restraints involve using a cement mix to secure the pavers. They provide a strong and long-lasting hold. This method is particularly effective for areas with heavy traffic since it prevents shifting. Mortar can be applied between the joints and along the edges, creating a solid boundary.
Installing mortar-based restraints requires skill. First, a trench is dug around the edges of the paver area. Mortar is then applied and the pavers are placed directly onto it. This method can be more time-consuming but offers superior durability.
One downside to mortar-based restraints is that they are less flexible in terms of design changes. If changes need to be made, the mortar must be removed and redone.
Flexible Edging Solutions
Flexible edging solutions use materials like plastic, metal, or rubber to keep pavers in place. These materials are often easier to install compared to mortar. Flexible edging is ideal for curves and intricate designs since it can be shaped to fit various layouts.
Plastic and rubber edges are common because they are light, easy to cut, and resistant to weather. Metal edges, typically made of aluminum or steel, offer more strength and are suitable for straight edges.
Installers set flexible edging by anchoring it into the ground with stakes. This method allows for simple adjustments and repairs. Flexibility makes it easier to design unique patterns and shapes.
Flexible edging may not provide as strong a hold as mortar, but it works well for projects with lighter traffic and for those looking for a quicker installation.
Installation Techniques for Edge Restraints
Proper installation of edge restraints is crucial for maintaining the integrity and appearance of paver surfaces. Key steps include preparing the base and correctly securing the restraints in place.
Excavation and Base Preparation
Before installing edge restraints, it is essential to prepare the area properly. Start by excavating a trench around the perimeter where the edge restraint will be placed. The depth of this trench should match the type of paver material being used, usually about 6-8 inches deep.
Next, fill the trench with a layer of crushed stone or gravel. This base layer acts as a foundation, providing stability and helping with drainage. Compact the base layer using a plate compactor to ensure it is firm and level.
After compacting, apply a thin layer of sand or stone dust on top of the base layer. This helps to create a smooth surface for the pavers and edge restraints to sit on. Make sure the base is uniform and even to prevent future movement or shifting.
Securing Methods and Stake Placement
Different methods are used to secure edge restraints, depending on the type of materials and the environment. For plastic or metal edge restraints, place them on the prepared base and line them up with the edges of the pavers.
Secure the edge restraints using stakes or spikes. Drive the stakes into the ground at a 45-degree angle towards the pavers to ensure they hold firmly. Position stakes every 12 to 18 inches for added stability. If using concrete edge restraints, mix the concrete according to the manufacturer’s instructions and pour it into forms set along the edges.
Allow the concrete to set for at least 24 hours before placing the pavers. This method is especially useful in areas with higher loads or vehicular traffic.
Always check the alignment of the edge restraints and make adjustments as needed. Properly installed edge restraints will prevent paver movement, maintaining the overall look and function of the paved area.
Material Compatibility and Selection
Proper edge restraint selection depends on matching the material to the paver type and considering the environmental impact. Careful selection helps ensure durability and functionality.
Matching Restraints to Paver Types
Different paver materials like concrete, brick, and stone require specific restraints. Concrete pavers pair well with plastic or aluminum restraints due to their uniform shape. Brick pavers benefit from sturdy steel or concrete restraints because they offer robust support.
Natural stone pavers often need flexible restraints such as plastic or metal spikes, allowing for irregular shapes and sizes. Ensure the restraint matches the flexibility and weight of the paver to prevent shifting. Compatibility here means considering the specific physical properties of both the restraint and the paver material.
Environmental Considerations
Choosing edge restraints also involves thinking about environmental factors. Climate plays a major role; areas with heavy rainfall might need corrosion-resistant materials like aluminum or treated steel. In hot climates, UV-resistant plastic can prevent cracking and fading.
Also, consider drainage requirements. Permeable pavers with specific restraints can help manage stormwater. Look for environmentally friendly options like recycled plastic. Ensure that the restraints do not negatively impact local wildlife or plant life, maintaining harmony with nature.
Maintenance and Longevity of Edge Restraints
Proper maintenance ensures that edge restraints last longer and perform effectively. Regular inspections and timely repairs are essential for the durability of edge restraints in different paver materials.
Routine Inspections
Regularly inspecting edge restraints is crucial. Look for signs of wear, such as cracks, shifting, or loosening. Pay attention to areas with heavy traffic as they tend to deteriorate faster.
Inspecting after extreme weather conditions helps in detecting early damages. After heavy rain or strong winds, examine the edges to see if they have moved or have any new damage.
A checklist can be helpful for inspections:
- Visible cracks
- Shifts in alignment
- Loose restraints
Taking notes during each inspection can track the aging process and plan maintenance.
Repair and Replacement Strategies
Timely repairs are critical. Small cracks or shifts should be fixed promptly to prevent larger problems. Material-specific adhesives and fillers can be used to address minor damages in concrete or plastic edge restraints.
In cases of severe damage, replacement is often the best option. For instance, metal restraints might bend or rust over time and require full replacement. Ensure replacement materials match the original to maintain consistency.
Having a maintenance schedule can ensure regular upkeep and prevent major issues. Make use of professional help if necessary to secure longevity and performance.
