Uneven pavers can quickly turn a beautiful outdoor area into a safety hazard or an eyesore. Whether it’s due to shifting soil, tree roots, or years of wear and tear, raised or sunken pavers are a common issue for many Perth homeowners.
In this guide, we’ll walk you through how to fix pavers so you can restore the look, safety, and functionality of your outdoor space.
Why Do Pavers Become Uneven?
Pavers can shift and settle over time because of a number of underlying issues. Here are some of the most common reasons:
-
Poor base preparation: If the ground wasn’t compacted properly or the base materials weren’t installed evenly, surrounding pavers may begin to sink or shift. Sinking pavers can become a tripping hazard.
-
Soil movement: Natural ground movement, especially in Perth’s sandy soils, can cause pavers to settle unevenly.
-
Tree roots: As roots grow beneath your patio, they can lift and displace pavers.
-
Water erosion: Poor drainage or heavy rains can wash away the bedding layer beneath pavers, leading to unevenness.
-
Heavy wear and tear: Regular foot traffic, furniture, or even vehicles (in driveways) can put stress on the pavers and cause them to move over time.
Understanding the cause of the issue is key to ensuring a lasting fix that keeps your patio both attractive and level.
Tools & Materials You’ll Need
Before you get started, gather the right tools and materials to make fixing sinking pavers easier and more efficient. Here’s what you’ll need to repair loose pavers:
Tools:
-
Rubber mallet
-
Flathead screwdriver or paver puller
-
Spirit level
-
Garden spade or small shovel
-
Broom
-
Hand tamper or plate compactor
Materials:
-
Bedding sand like washed river sand or paving sand
-
Cracker dust or road base if you’re redoing the foundation
-
Replacement pavers if any are damaged
-
Jointing sand to refill the gaps between pavers
Having everything on hand before you begin will help you complete the job more smoothly and avoid unnecessary delays.
Step-by-Step Guide to Removing & Resetting Uneven Pavers
Fixing uneven patio pavers isn’t as complicated as it might seem. With a bit of time and the right technique, you can restore a level and safe pavement. Follow these steps:
1. Identify the Problem Area
Use a spirit level or straight edge to pinpoint which pavers are uneven. Mark these to remove so you can focus only on the affected spots.
2. Carefully Remove the Uneven Pavers
Insert a flathead screwdriver or paver puller between the joints and gently lift the pavers out. Avoid using too much force so you don’t crack or chip them.
3. Check the Base
Inspect the paver sand or base layer beneath. If it’s eroded, washed out, or compacted unevenly, it will need to be re-levelled or replaced.
4. Rebuild the Base (If Needed)
If the issue is with the sub-base, dig a bit deeper and add compacted gravel or road base or cracker dust to create a solid foundation. Use a hand tamper or plate compactor to flatten it.
5. Add and Level the Bedding Sand
Spread a fresh layer of bedding sand and level it with a straight edge. Aim for a smooth, even surface roughly 25–30mm deep.
6. Reset the Pavers
Place the pavers back into position, aligning them with the surrounding layout. Lightly tap each one gently with a rubber mallet to set them into place evenly.
7. Check for Level
Use a spirit level to ensure each paver sits flush with the surrounding pavers. Adjust as needed by adding or removing sand.
8. Refill the Joints
Once all pavers are in place, sweep jointing sand into the gaps. This helps lock them together and prevents future shifting.
9. Compact the Area
Lightly compact the area again to bed everything in properly and top up any joints where the sand has settled. Brush away the excess sand on the pavers.
By following these steps to fix loose pavers, you’ll restore your patio surface to its best condition, level, stable, and ready to enjoy again. If you’re upgrading your entire outdoor space, Great Aussie Patios can help you tie it all together with a stylish, custom-built patio roof.
Preventing Future Shifting & Unevenness
Once you've fixed your uneven pavers, taking steps to stop the issue from happening again can save time, money, and frustration. Here’s how to keep your patio surface stable long-term:
Ensure proper drainage
Standing water can erode the base beneath your pavers. Make sure your patio slopes slightly away from buildings and has enough drainage to stop water from pooling.
Compact the base thoroughly
A poorly compacted base is one of the most common causes of paver movement. Use a hand tamper or plate compactor during installation or repairs to create a firm, level foundation.
Use high-quality bedding sand
Washed river sand or paving sand creates a stable bedding layer that supports your pavers and allows for good compaction and drainage.
Control surrounding vegetation
Keep tree roots at bay by installing root barriers or choosing patio plants that won’t disturb your paved areas.
Top up jointing sand regularly
Over time, jointing sand can wash out or settle. Replenish it as needed to keep pavers locked in place and prevent lateral movement.
Avoid overloading the area
Ensure that your patio is used as intended. If it’s not designed for heavy loads, avoid parking vehicles or placing overly heavy furniture on it.
With the right preparation and ongoing maintenance, your pavers will stay secure and level for years to come. And if you’re planning a full outdoor transformation, Great Aussie Patios is here to help design and build the perfect covered space to match your newly level surface.
When to DIY vs Hire a Pro
Fixing a few uneven pavers can be a straightforward DIY project if the affected area is small, the base is still in good condition, and you’re comfortable using basic tools. It’s a great option if you have the time and want to save on labour costs.
However, if the unevenness covers a larger area, or if there are underlying issues like drainage problems, shifting soil, or tree root interference, it’s best to call in a professional. The same applies if the original paving job was poorly done and needs a more thorough fix.
