Do I Need Joints in Brick Paver Patio?

When it comes to installing a brick paver patio, one might wonder if it’s necessary to have joints between the pavers. The answer is yes, and for good reason. These joints play a crucial role in preventing the pavers from becoming loose, shifting, or settling due to erosion. It’s surprising, however, that many homeowners neglect this vital aspect of paver maintenance. The simple and effortless task of sweeping in paver joint sand is often overlooked, with homeowners failing to realize it’s importance in ensuring the longevity and stability of their patio.

What Happens if You Don’t Put Sand Between Pavers?

Without proper joint stabilization, the structural integrity of your paver installation is at risk. The purpose of filling the gaps between pavers with sand is to create a solid foundation and prevent movement. If you skip this step, the consequences can be far-reaching.

One immediate effect of not using sand between pavers is the risk of water damage. When rainwater or pool water accumulates in the joints, it seeps into the base material below the pavers and can potentially wash it away. This compromises the stability of the entire installation and can lead to loose, wobbly, and uneven pavers. Without sand, even the slightest weight or pressure can cause the pavers to sink or raise up, creating uneven surfaces that aren’t only unsightly but also hazardous to walk on.

In addition to physical damage, not using sand between pavers can also result in weed growth. The gaps between the pavers create perfect conditions for weeds to take root and thrive. Without joint sand, their growth becomes even more pronounced, as there’s no barrier to impede their progress. This not only ruins the aesthetics of your installation but also requires constant maintenance to keep the weeds under control.

Lastly, skipping the sand bed can impact the overall appearance of your paver project. Without the joint sand, the gaps between the pavers will be more noticeable, detracting from the clean and uniform look that’s typically desired. The absence of the soft filler also means that the pavers can shift more easily, leading to unsightly gaps and irregular patterns.

From water damage and uneven surfaces to weed growth and compromised visuals, the risks and consequences are significant. It’s essential to follow proper installation practices to ensure a long-lasting and visually pleasing paver project.

The Process of Properly Filling the Gaps Between Pavers With Sand

The process of properly filling the gaps between pavers with sand involves carefully pouring sand into the spaces between the pavers to ensure stability and prevent weeds or other debris from filling the gaps. This can be accomplished by using a broom to sweep the sand into the gaps, making sure it’s evenly distributed. The sand should be compacted by using a tamper or vibrating plate to ensure a solid, level surface. In the end, the gaps should be completely filled with sand, leaving no empty spaces or unevenness.

In addition, sand helps to prevent weed growth, promotes proper drainage, and enhances the overall appearance and durability of the paver installation. Therefore, it’s essential to regularly re-sand the joints to maintain the stability and longevity of your brick pavers.

Should I Put Sand Between My Pavers?

In addition, the sand acts as a barrier to prevent weed growth and helps to absorb moisture, preventing water from seeping under the pavers and causing damage. Without sand, the pavers may shift and become uneven, compromising their stability and overall aesthetic appeal.

Re-sanding brick paver joints is crucial because over time, the sand may become displaced or worn away due to foot traffic, weather conditions, or regular maintenance. As the sand deteriorates, gaps between the pavers begin to form, allowing for weed growth and potential instability.

When re-sanding, it’s important to choose the right type of sand. Polymeric sand is highly recommended as it contains additives that bind the sand particles together when activated by water. This results in a firm and durable joint that’s less likely to wash away or be disturbed by foot traffic.

Next, evenly distribute the polymeric sand over the surface, making sure it fills the gaps between the pavers completely. Use a broom or brush to sweep the sand into the cracks, gently tapping the pavers to ensure the sand settles evenly.

Once the sand is in place, use a hose to lightly mist the area, activating the binding agents in the polymeric sand. Allow the sand to fully dry and settle for the recommended time specified by the manufacturer before proceeding with sealing the pavers.

By following the proper technique and using the right type of sand, you can ensure a seamless and durable joint that will enhance the appearance and functionality of your paver installation.

It’s important to understand that pavers do indeed require expansion joints. These joints play a crucial role in providing flexibility for the movement of both the concrete paving and the base slab. As such, the inclusion of control joints and expansion joints should be carefully considered during the design phase, particularly for extensive areas of paving.

Do Pavers Need Expansion Joints?

Without these joints, the paving may crack and become damaged over time. Expansion joints, also known as isolation joints, accommodate the expansion and contraction of the concrete caused by temperature changes.

Without expansion joints, the concrete wouldn’t have the space it needs to expand and contract, resulting in cracks and potentially uneven surfaces. These joints act as a buffer and prevent the concrete from cracking under stress.

In addition to expansion joints, control joints are also important for maintaining the structural integrity of the paving. These joints are strategically placed to control where cracks occur in the concrete, directing them along predetermined paths.

Adequate jointing of paving is crucial for it’s long-term durability and stability.

The design phase is the ideal time to determine the placement and size of expansion and control joints. Factors such as climate, site conditions, and the type of paving material should all be considered when determining the spacing and dimensions of these joints.

Pavers do need expansion joints to accommodate the movement of the concrete caused by temperature changes. Proper planning and consideration should be given to the placement and size of these joints during the design phase to ensure a successful and long-lasting paving installation.

This will create a solid and stable surface for walking and prevent the pavers from shifting or sinking over time. On the other hand, if you’re installing pavers for a driveway or a pathway, it’s recommended to leave a small gap between each paver. This gap will allow for proper drainage and flexibility, reducing the chances of cracking or damage due to ground movement. Additionally, adding joint sand between the pavers can further enhance stability and prevent weed growth. Overall, leaving gaps between pavers is essential for a durable and long-lasting paved surface.

Do You Need Gaps Between Pavers?

This will create a seamless and solid surface that’s less likely to shift or become uneven over time. On the other hand, if youre using pavers for a pathway or driveway, it’s important to leave some space between them.

The main reason for leaving gaps between pavers is to allow for adequate drainage. When water falls on a paved surface, it needs somewhere to go. By creating small gaps between the pavers, youre providing a path for the water to flow through and into the ground. This helps to prevent puddles and water buildup, which can lead to erosion and damage to the pavers.

Concrete pavers, like any other material, expand and contract with temperature changes. Without sufficient space to move, the pavers can become stressed and crack or become uneven. By leaving gaps, youre allowing the pavers to naturally adjust to temperature variations, reducing the risk of damage.

Many people prefer the look of pavers with visible gaps. It adds a sense of dimension, texture, and character to the paved surface. It also allows for the use of decorative materials, such as gravel or moss, to fill in the gaps and create a more unique and visually appealing design.

In summary, whether youre laying concrete pavers for a patio, pathway, or driveway, leaving gaps between them is highly recommended. The size of the gap will depend on the type of pavers and the purpose of the paving. Gaps provide essential drainage, allow for expansion and contraction, and enhance the overall aesthetic of the paved surface. So, when in doubt, leave a gap!


In conclusion, the importance of including joints in a brick paver patio can’t be emphasized enough. By being aware of the significance of full paver joints and actively performing this basic upkeep, homeowners can ensure the longevity and stability of their beautiful brick paver patios.
