What is the difference between paver sand and polymeric sand? When it comes to laying pavers, the choice of sand is crucial for the stability and longevity of the paving project. Both paver sand and polymeric sand are used in the installation process, but they have distinct properties and applications. Understanding these differences can help you make an informed decision for your next paving project.
Polymeric sand is a specialized type of sand that contains a polymer, which is a chemical compound. This polymer acts as a binder, allowing the sand to set and harden when it comes into contact with water. Once cured, polymeric sand forms a strong, durable bond between the pavers, preventing weed growth and reducing the amount of sand that is washed away over time. It is commonly used in outdoor paving projects, such as patios, driveways, and walkways, where a long-lasting, low-maintenance solution is desired.
On the other hand, paver sand, also known as jointing sand, is a fine-grained sand that is used to fill the gaps between pavers. It is typically composed of natural sand and does not contain any polymer. Paver sand is suitable for both indoor and outdoor paving projects and is available in various sizes, with fine sand being ideal for tight joints and coarse sand for larger gaps. While paver sand does not provide the same level of durability as polymeric sand, it is more cost-effective and easier to work with.
One of the main differences between paver sand and polymeric sand is their application. Polymeric sand is primarily used for creating a waterproof barrier between pavers, which helps to prevent water from seeping into the ground and causing damage. This makes it an excellent choice for areas that are prone to heavy rainfall or flooding. Paver sand, on the other hand, is used to fill the gaps between pavers and provide a stable base for the pavers to sit on. It also helps to prevent weeds from growing through the gaps and to maintain the aesthetic appearance of the paving project.
Another difference between the two types of sand is their curing time. Polymeric sand requires a curing period of several days to several weeks, depending on the temperature and humidity of the environment. During this time, the polymer in the sand needs to cure and harden, forming a bond between the pavers. Paver sand, on the other hand, does not require any curing time and can be used immediately after laying the pavers.
In conclusion, the main difference between paver sand and polymeric sand lies in their properties, applications, and curing times. Polymeric sand is a specialized type of sand that provides a durable, waterproof barrier between pavers, while paver sand is a more cost-effective and versatile option for filling gaps and providing a stable base. Choosing the right type of sand for your paving project will depend on your specific needs, budget, and desired level of maintenance.
