Do Pavers Shift Over Time?
Pavers are blocks, concrete, or bricks used to create hard-surfaced pathways, patios, driveways, and other outdoor areas. They are widely used for residential and commercial landscaping projects due to their durability, aesthetic appeal, and ease of installation. The question is, do pavers shift over time after installation?
Do Pavers Shift Over Time?
Yes, pavers can shift and move over time due to various factors such as ground movement, poor installation, and dramatic temperature changes. In most cases, improper edging tends to be the leading cause of pavers shifting. When the edges of the pavers need to be properly secured with an appropriate edging material, the pavers can shift and move.
When deciding to use pavers for a project, it is vital to know the possible problems that could arise over time. One such problem is the shifting of the pavers. When a paver shifts, it can become uneven or even create gaps between them, resulting in an unsafe walkway or patio area.
Why Do Pavers Shift?
It is common that when you install pavers, you will want them to last a long time; however, they are resistant to shifting. Several factors can influence the shifting of pavers, including:
Bedding Sand Wasn’t Installed Properly
One of the most common reasons pavers shift is improper installation of bedding sand. Bedding sand, which provides a cushion between the paver and the subbase material, needs to be installed correctly. If the bedding sand is not compacted properly or has too much moisture, the pavers can shift, leading to gaps and an uneven surface.
Experts will use a process called screeding to ensure the bedding sand is at a consistent depth, then use a plate compactor to ensure it is properly compacted. This way, the pavers are not overly supported or allowed to move.
Improper Installation of the Pavers
Installation of pavers is more involved than simply laying them down. It is important to follow the manufacturer's instructions to ensure that the pavers are laid correctly, including proper gaps between each paver and the correct amount of sand or mortar. If the pavers are not laid correctly, they can shift and create gaps, resulting in an unsafe walking surface.
Hiring a professional paver installer when installing pavers is vital, as they are experienced and knowledgeable in the proper techniques and materials. At Aviara Pavers, our experienced and certified contractors can provide a high-quality installation that will last for many years. We are a company that follows ICPI standards and best practices for paver installation for patios, driveways, entryways, pool decks, and outdoor spaces.
Temperature Changes
Dramatic temperature shifts can also cause pavers to shift over time. During the winter months, when temperatures drop below freezing, and freeze-thaw cycles occur, pavers can shift due to the expansion and contraction of the materials used in the installation.
Temperature changes can also cause small gaps to appear between the pavers. To prevent this, experts suggest using polymeric sand in the installation process. This type of sand is designed to expand and contract with the temperature, reducing the chances of gaps appearing between the pavers.
Having Long Linear Lines
Another cause of paver shifting has long linear lines. When pavers are laid out in long straight lines, there is more pressure on the edges of the pavers, and they can easily move or shift due to ground movement.
Long linear lines compromise the integrity of the paver installation, and it is advised to use a variety of patterns when laying pavers. A pattern with curves, circles, and angles helps distribute the pressure evenly across the entire area and reduces the likelihood of shifting or movement over time.
Tree Roots
Tree roots can also be a major cause of paver shifting. When the roots grow underneath the pavers, they can push them up, leading to an uneven and potentially unsafe walking surface. Tree roots can also cause pavers to crack as they grow and spread.
To avoid these issues, it is important to know if trees are nearby when preparing to install pavers. If there are, then it is best to remove the trees or relocate them elsewhere, as they can cause major damage in the long run.
What Can You Do to Prevent Shifting?
If you are a homeowner looking to install pavers, there are steps you can take to ensure they do not shift. You want to avoid going through all the trouble and cost of installing pavers only to find that they need to be replaced a few years later. The following tips can help:
Hire a professional paver installer to help with the installation since they have the necessary experience and techniques to ensure a high-quality installation
Use polymeric sand instead of regular sand to help prevent gaps between pavers
Avoid long linear lines when laying pavers and instead use a pattern that contains curves, circles, and angles
Be aware of nearby trees and remove them if necessary to prevent root damage
Ensure Proper Maintenance and care once the pavers are installed correctly. This includes regularly removing moss and cleaning paver dirt and debris, sealing the pavers every two years, and checking for any damage signs.
Frequently Asked Questions
What Is the Life Expectancy of Pavers?
The life expectancy of pavers depends on the type of material used, installation quality, and maintenance. Generally speaking, brick and concrete pavers can last from 50-100 years. However, the durability of pavers can be extended with proper installation and regular maintenance.
Do Pavers Need to Be Sealed?
Yes, it is recommended that pavers be sealed at least every two years to protect them from stains, fading, and other damage. Sealing helps maintain the aesthetic beauty of your pavers and ensures they last longer.
Are Pavers High Maintenance?
No, pavers are not high maintenance. They only require regular sweeping, occasional power-washing, and occasional sealing to keep them looking their best. Regular maintenance can help extend the life of your pavers and keep them looking great for years to come.
Conclusion
Shifting and movement of pavers over time is a common problem that homeowners run into. However, this likelihood can be reduced with proper installation, choosing the right materials, and regular maintenance. By following these tips, your pavers can look great for years. Happy paving!
