What is pavers polymeric sand?

Polymeric sand is a specialized material used for jointing paving slabs and brick pavers. It is made of fine silica sand combined with water-activated polymers that harden and bind the sand particles together, forming a flexible joint. Polymeric sand provides adhesion, permeability, longevity, ease of use, and weed and pest deterrence. It enhances the durability and stability of the pavers, making it a popular choice for paver installation and maintenance projects. Here are the key characteristics and benefits of polymeric sand:

1. Composition:
   • Polymeric sand is a blend of coarse-grained sand and special additives, including polymers and binding agents. These additives react with water to form a strong bond.
2. Function:
   • The primary purpose of polymeric sand is to stabilize the joints between pavers, preventing them from shifting or becoming uneven. It also helps to prevent weed growth and insect infestations by creating a nearly airtight seal.
3. Installation:
   • The installation process involves sweeping the polymeric sand into the joints, compacting the pavers to settle the sand, and then activating the binding agents with water. It is crucial to ensure the pavers are dry and free of dust to avoid staining.
4. Benefits:
   • Durability: Polymeric sand forms a strong and durable bond, significantly increasing the lifespan of the paver installation by resisting erosion and preventing joint sand washout.
   • Weed and Pest Prevention: It inhibits weed growth and pest infestations, maintaining the aesthetic appeal and structural integrity of the pavers.
   • Aesthetic Options: Available in various colors, allowing for a match with different types of pavers.
   • Ease of Use: While requiring some care during installation, polymeric sand is generally easy to apply and can be used on both horizontal and sloped surfaces.
5. Performance:
   • Polymeric sand sets quickly after water is applied and can be used in a variety of environmental conditions, including areas exposed to rain, wind, and freezing temperatures.
   • It helps prevent damages caused by climatic conditions and maintains pavers securely in place.

Polymeric sand is also a type of sand that contains polymer binders. These binders help to hold the pavers in place and prevent them from shifting or moving. Polymeric sand is specifically designed for filling the joints between pavers, providing enhanced adhesion, permeability, and longevity. It also deters weeds and pests, making it an ideal choice for maintaining the structural integrity and aesthetic appeal of a paver installation.

Overall, polymeric sand is a superior choice for paver jointing due to its enhanced durability, weed and pest resistance, and ease of installation.
