Why do pavers sink?
One of the most common questions we get here at Paver Pete’s is “Why do pavers sink?” We thought it would be helpful to address this issue in a blog post.
There are a few reasons why pavers might sink:
1. Poorly compacted base: If the base material underneath your pavers is not compacted properly, it will settle over time and cause your pavers to sink.
2. Incorrect paver size: If you use pavers that are too small for your project, they will sink over time as people walk on them.
3. Use of sand instead of gravel: Sand is a much finer material than gravel, so it doesn’t provide the same level of support. Over time, sand will settle and cause your pavers to sink.
4. Use of mortar instead of polymeric sand: Mortar is a cement-based product that is used to adhere brick and stone together. While mortar can provide a strong bond, it is not flexible like polymeric sand. When mortar cracks, it allows water to seep in and compromise the bond between the paver and the mortar bedding, causing the paver to sink.
How to keep your pavers from sinking
Pavers are a beautiful and popular choice for many homeowners. They are easy to install and can provide a high-end look to any home. However, one of the downsides of pavers is that they can sink over time. This can be due to a number of factors, such as poor installation, soil erosion, or even just heavy traffic. If your pavers are starting to sink, there are a few things you can do to fix the problem.
Choose the right pavers
When choosing pavers for your outdoor project, make sure to choose those that are made from durable materials that can withstand the elements. Also, make sure to pick a paver that is the right size and shape for the area you’re working on.
Prepare the ground before you lay the pavers
One of the best ways to prevent your pavers from sinking is to prepare the ground before you lay the pavers. The ground should be flat and level, and you should use a layer of gravel or sand to create a stable base. If you are using pavers that are 50mm (2 inches) thick or more, you should also use a layer of concrete to create a solid foundation.
Once the foundation is prepared, you can start laying the pavers. Make sure that each paver is level with the others, and use a space between each paver so that there is room for expansion. If you are using concrete pavers, be sure to use a sealant on the joints to keep water from seeping into the cracks.
Use the right adhesive
There are a few things you can do to keep your pavers from sinking, but it starts with using the right adhesive. Look for an adhesive that is specifically designed for pavers, and make sure it is outdoor-rated and waterproof. You may also want to use two types of adhesives to be extra safe – a core adhesive to hold the pavers together, and a surface adhesive to keep them from shifting.
Lay the pavers correctly
The correct way to lay pavers is to start at one end and work your way towards the other. Begin by laying the pavers along the edge of the area to be paved. Use string or a straight edge to make sure that the first row of pavers is level. The next row of pavers should be offset so that they are not directly above or below the first row of pavers. This offset is usually done by half a paver width.
How to fix sunken pavers
Pavers can add a lot of beauty and value to your home, but they can also be a bit of a hassle. If your pavers are sinking, it can not only be unsightly, but it can also be dangerous. Luckily, there are a few things you can do to fix the problem.
Remove the sunken pavers
To remove the pavers, place the chisel at a 45-degree angle underneath the stone. Use a mallet or small sledgehammer to tap the chisel and loosen the paver. You may need to work the chisel back and forth to loosen the paver. Once it is loose, pry it up with your hand or a small pry bar. Repeat for all of the sunken pavers.
Prepare the ground
Whether your pavers are new or have been in place for years, it’s important to properly prepare the ground before attempting any repair work. Start by removing any weeds or grass that is growing between the pavers. Next, use a hard bristled brush to remove any loose dirt or debris.
Once the area is clean, you will need to apply a layer of sand over the entire surface. Use a push broom to spread the sand evenly, being sure to fill in all the cracks and crevices. The sand will act as a buffer between the pavers and the ground, helping to keep your pavers level and in place.
Relay the pavers
Sunken pavers can be a real eyesore, and can pose a safety hazard if they’re not fixed. But don’t worry, there is a fix! By relayering the pavers, you can easily fix sunken pavers and have your patio or walkway looking like new in no time. Here’s what you need to do:
-Use a power washer to clean the area around the sunken pavers. You want to make sure that all of the dirt, debris, and weeds are removed so that you have a clean surface to work with.
-Next, use a chisel and hammer to remove the sunken pavers. Be careful not to damage the surrounding pavers as you remove them.
-Once the sunken pavers are removed, use a trowel to level off the area where they were removed. You want to make sure that the area is level so that your new pavers will lay flat.
-Now it’s time to lay your new pavers! Lay them in the same pattern as the surrounding pavers, making sure that they are level with the rest of the patio or walkway. Use a level to make sure that they are even.
-Finally, use sand to fill in any cracks or gaps between the new pavers and the old ones. This will help to keep everything in place and prevent future sinking.
