How to Prevent Pavers From Sinking?

Paver Patio

A paver patio is an outdoor living setting constructed from interlocking paver stones that are durable and available in a range of sizes, shapes, and colors. Paver patio cost can vary depending on various factors such as the size of the patio, the type of patio, the complexity of the design, and the location of the project. Paver patios can cost anywhere from $10 to $25 per square foot. 

Paver patio installation involves creating a flat surface with a compacted gravel base and then laying down interlocking pavers in a desired pattern on top. The first step in the installation process is to mark out the area where the patio will be built and excavate the soil to the required depth. Next, a layer of crushed stone or gravel is spread over the excavated area and compacted to provide a solid and level base for the patio. Once the base is prepared, the pavers are laid on top of the base in the desired pattern. The pavers are interlocked using sand or another filler material, which is brushed into the spaces between them to keep them securely in place. The final step is to compact the pavers with a mechanical compactor to ensure a level and stable surface.

A paver patio pattern is one of the different designs or arrangements of pavers used to create a patio. Pavers are individual units made from materials like concrete, stone, and brick, which can be arranged in various patterns to create a unique and aesthetically pleasing outdoor space. The pattern chosen can have a significant impact on the overall appearance and functionality of the patio.

How to Prevent Pavers From Sinking?

Sinking pavers can cause many damages, so, the steps necessary to prevent pavers from sinking and ensure that your installation remains stable and functional for years to come. So here are some steps to prevent paving stones from sinking: 

  • Proper preparation of the base: Make sure the base for your pavers is properly prepared. This means removing any vegetation or debris, excavating the soil to the required depth, and adding a layer of crushed stone or sand as a base for the pavers. It will help ensure that the pavers remain stable and don’t sink.
  • Use the right materials: Make sure you are using the right materials for your paver installation. Use high-quality pavers that are designed for your specific application, and use the right type of crushed stone or sand for your base.
  • Proper compaction: Properly compact the base material before laying the pavers. This will help ensure that the base is stable and won’t shift over time, which can cause the pavers to sink.
  • Use edge restraints: They keep the pavers in place and are typically made of plastic or metal. They are installed around the perimeter of the paver installation to keep the pavers from shifting or spreading out over time.
  • Maintain proper drainage: Ensure that water is able to drain away from the pavers. Poor drainage can cause the soil underneath the pavers to become saturated and soft, which can lead to sinking. Make sure that the slope of the ground around the pavers is appropriate and that any nearby drainage systems are functioning properly.



Different factors that cause pavers to sink.

Here are the different factors that cause a paver to sink, which include:

  • Poor Base: One of the primary reasons why pavers sink  is a poorly constructed base. If the base is not compacted enough, it can shift and settle over time, causing the pavers to sink and become uneven.
  • Heavy Traffic: Areas that experience heavy foot or vehicular traffic are more prone to paver sinking. The constant pressure exerted on the pavers can cause them to sink into the soil below.
  • Drainage Issues: Improper drainage can cause water to accumulate under the pavers, causing the soil to become saturated and soft. This can lead to sinking and shifting of the pavers.
  • Soil Type: The type of soil on which the pavers are installed can also affect their stability. Soils with high clay content or organic matter tend to be more unstable and prone to sinking.
  • Weather Conditions: Extreme weather conditions, such as heavy rainfall, snow, and freezing temperatures, can also cause pavers to sink. Water can seep into the base and freeze, causing it to expand and push the pavers up.
  • Installation Issues: Improper installation techniques, such as incorrect spacing between the pavers or inadequate joint sand, can also lead to sinking and shifting over time.
  • Natural Settlement: Natural settlement of the ground over time can cause pavers to sink. This is particularly true in areas with loose or sandy soils.
