Can I Use Regular Sand Between Pavers?

If you're considering using regular sand between pavers for your backyard patio or pathways, you might be wondering if it's a suitable choice. While it may seem like a simple and cost-effective solution, there are some factors to consider that could influence your decision.

To start, let's understand that the space between pavers, known as the joint, serves two primary purposes: stability and drainage. Good drainage prevents water from building up and pushing the pavers upwards, while stability ensures the pavers remain level and securely in place.

Understanding Paver Joints

Paver joints typically range between 1/8" to 1/2", with the ideal joint width dependent on the paver size and the base material. The joint width directly impacts how much sand you'll need to fill the space.

Now, let's delve into the two primary sand types used for paver joints: regular sand and polymeric sand. Each has its unique characteristics, advantages, and disadvantages.

Regular Sand

Regular sand, also known as mason sand or regular sand, is a common, affordable option for paver joints. It's typically used for wide joints (3/8" to 1/2") and is available in either natural or washed varieties. Natural sand contains small amounts of clay, while washed sand is free from clay and silt.

One of the primary advantages of regular sand is its ability to flow easily, making it simpler to fill large joints evenly. However, this ease of flow can also be a disadvantage, as it may wash out with heavy rain or, worse, shift slightly during the curing phase, leading to uneven pavers.

Polymeric Sand

Polymeric sand is a mixture of regular sand and a polymer additive that binds the sand grains together when wet, creating a stable, solid joint. This type of sand is ideal for narrow joints (1/8" to 5/8") and offers better stability and drainage than regular sand.

Polymeric sand's strength lies in its durability and resistance to weed growth. However, it's more expensive than regular sand and can be more challenging to work with, especially in cold or humid weather.

Can You Use Regular Sand between Pavers?

The short answer is yes, you can use regular sand between pavers. However, it's crucial to weigh the pros and cons based on your specific project and local climate.

For wide joints and budgets that prioritize cost-efficiency over long-term stability, regular sand can be an appropriate choice. Keep in mind, though, that you may need to touch up your paver joints more frequently due to regular sand's susceptibility to erosion and shifting.

best Practices with Regular Sand

If you decide to use regular sand, ensure you follow best practices for optimal results:

• Use the correct sand type based on your joint width.
• Wet the base and paver surface before application to minimize sand blowout.
• Fill the joints, compacting the sand using a tool like a rubber mallet or plate compactor.
• Immediately sweep and forcibly flush the joint surface to remove excess sand.
• Allow the sand time to set before subjecting it to heavy foot or vehicle traffic.

When Regular Sand Might Not Be the Best Choice

Regular sand might not be the best choice in certain circumstances. For instance, if you're working with narrow joints (under 3/8"), polymeric sand may be more suitable. In areas with heavy rainfall or freeze-thaw cycles, polymeric sand can offer better durability.

Additionally, if weed growth is a concern, you might want to consider using a herbicide-treated sand or polymeric sand, which helps deter weed growth by creating a solid barrier.

In conclusion, while regular sand can be a cost-effective option for paver joints, it's essential to consider your project's specific needs and potential long-term maintenance. By understanding the pros and cons of regular sand and comparing it to other sand types, you can make an informed decision that best suits your project's requirements. So, go ahead and plan your paver project with confidence, knowing you've made the right choice for your outdoor space.
