Is your paver patio showing signs of movement this winter? You are not alone. Many homeowners in Fredericton notice their once-perfect paver surfaces starting to shift and sink during the cold months. This natural phenomenon affects driveways, walkways, and patios across colder regions. Understanding why your pavers move during winter can help you prevent damage and maintain your outdoor living space. Let’s explore the science behind winter paver movement and learn how proper installation, maintenance, and care can protect your landscape investment from the harsh effects of freezing temperatures.
Think of your landscape like a layered cake. When winter hits, water trapped in the soil under your pavers freezes. Just like when ice cubes form in your freezer tray, this frozen water expands. This expansion creates an upward force that can make your pavers shift and move over time.
Your paver patio or walkway might be more prone to frost heave depending on a few things. Sandy soils tend to drain better, while clay soils hold more water and are more likely to cause problems. Areas that get lots of shade can stay frozen longer, and poor drainage can make things worse.
Here’s what you might see happening to your outdoor space:
The freeze and thaw cycles during winter can really do a number on your hardscape if it wasn’t built properly. That’s why proper base preparation and drainage are so important during the installation process. A properly compacted base and the right materials can help prevent these winter headaches.
Think of your paver patio as a blanket laid over the ground. When winter ends and temperatures rise, something interesting happens beneath that blanket. The frozen ground starts to thaw, and all that expanded ice turns back into water. This is where your pavers might start playing hide and seek with your landscape design!
As the ground underneath thaws, it doesn’t always settle back evenly. Imagine stirring a cup of hot chocolate – some parts mix faster than others. That’s similar to how your outdoor space responds to warming temperatures. Some areas might thaw quickly while others take their time, leading to uneven settling that can make your pavers sink or shift in different spots. This is particularly noticeable in areas where the base was not properly prepared during the initial paver installation.
Your driveway or patio area might show various signs of settling. You could notice some pavers sinking lower than others, or gaps appearing between paver stones. Sometimes you’ll spot dips forming in certain areas, while the edges of the pavers become misaligned. These issues often appear near pool areas or where drainage isn’t optimal, making your once-level surface look a bit wobbly.
The good news is that interlocking pavers can be fixed when they become uneven. Unlike solid concrete, paver stones can be lifted and reset when the ground shifts. However, if your base material wasn’t properly compacted during installation, you might see these issues occur more frequently. That’s why having proper drainage and ensuring your pavers are laid on a properly prepared base is so important for maintaining your outdoor living space. Regular maintenance and addressing any drainage issues early can help your patio last for many years.
Your paver problems might stem from improper installation techniques. A proper base requires careful preparation and attention to detail during the installation process. The foundation needs sufficient depth to support the weight of both the pavers and any expected traffic. The base material must be properly compacted in layers to prevent future settling, using appropriate materials that promote effective drainage. Installing edge restraints around the perimeter keeps pavers from spreading outward under pressure.
Poor drainage is particularly problematic, as it allows water to accumulate beneath the surface. When water pools in these areas, it intensifies the effects of freeze-thaw cycles. Think of it as building a house – without a solid foundation and proper water management, structural issues are almost inevitable.
The materials in your paver installation respond differently to temperature fluctuations, much like how various materials in your home expand and contract at different rates. The stones, sand, and base materials each react uniquely to temperature changes, creating subtle movements within your paver structure. These tiny shifts might seem insignificant at first, but over time they can create spaces between pavers where water can infiltrate.
This thermal movement is natural and unavoidable, but proper installation techniques can help minimize its impact. The key lies in using appropriate joint sand and maintaining proper spacing between pavers to accommodate these natural movements while preserving the integrity of your outdoor space.
Metal shovels and snowplow blades are like sandpaper against your paver stones. When you drag these tools across your landscape, they can leave scratches, chips, and cracks in your pavers. It’s similar to using a metal spoon on a non-stick pan – the surface gets damaged bit by bit. These seemingly small marks create perfect hiding spots for water, which can freeze and cause your pavers to shift over time.
The way you remove snow matters too. Forceful shoveling can disturb the carefully laid pattern of your interlocking pavers. This rough treatment can loosen the edge restraints and disrupt the base material underneath, leading to uneven pavers when spring arrives.
The joint sand between your pavers plays a vital role in keeping water out. When you scrape away snow too aggressively, you might also remove this important sand. Without proper joint sand, water seeps down between the paver stones, creating a perfect setup for freeze-thaw cycles that can make your pavers sink or shift. Using ice melt products properly is also key – too much can damage your paver surface and make it more likely to absorb water.
If you want to protect your outdoor living space, consider hiring professionals for snow removal from your paver driveway or walkway. They understand how to keep your pavers free and clear of ice while preventing damage. With proper care, your patio can maintain its beauty through many winters to come.

While some minor seasonal movement is natural in paver installations, significant shifting typically indicates underlying problems. Natural settling during the first year is common, but ongoing movement suggests installation issues or maintenance needs.
Call for emergency paver repair immediately if you notice sudden, significant shifting or sinking of pavers, as this could indicate serious problems like broken water pipes or severe erosion underneath. Don’t delay if you spot cracked or broken pavers alongside the shifting, as this weakens your entire paver surface and can lead to more extensive damage. Watch for warning signs like exposed base material or water flowing beneath the pavers, especially if the area supports heavy weight or structures – these conditions can quickly lead to dangerous collapses if left unaddressed.
While repairing pavers during winter presents challenges, it’s not entirely impossible. The freezing temperatures and snow can make it difficult to properly reset pavers or compact the base material, but emergency repairs can be done if necessary. For best results, however, it’s recommended to wait for warmer temperatures when the ground has thawed and materials can be properly worked with to ensure a lasting repair.
