What Is Resin Bonded Gravel
Resin bonded gravel is a decorative and durable surface solution often used for driveways, pathways, patios, and other exterior spaces. It consists of a layer of loose gravel that is adhered to a substrate using a high-performance resin. While it shares similarities with resin bound gravel, resin bonded gravel has distinct differences that make it unique in terms of installation and appearance.
Composition and Installation
The process of creating resin bonded gravel begins by applying a layer of clear, UV-stable resin over an existing surface, such as concrete or tarmac. Once the resin is spread evenly, loose gravel or decorative aggregates are broadcast onto the resin layer. The aggregate used can vary, ranging from natural stone pebbles to colored gravels, depending on the desired aesthetic. After the resin has cured, the gravel particles are adhered to the surface, leaving them loose but firmly embedded in the resin.
Unlike resin bound gravel, where the aggregate is mixed with the resin before being laid down, resin bonded gravel results in a surface with a more textured and loose appearance, with visible gravel particles protruding above the resin. This gives it a distinctive, rougher texture compared to the smoother finish of resin bound gravel.
Advantages of Resin Bonded Gravel
Aesthetic Appeal: Resin bonded gravel provides a highly customizable and attractive surface. The variety of colors and textures available in the gravel means homeowners can create a unique, natural-looking finish to suit the surrounding environment. It can be used to complement both modern and traditional styles of architecture.
Durability: Resin bonded gravel is highly durable, providing long-lasting protection against heavy foot traffic, vehicular traffic, and weather conditions. The resin forms a strong bond with the gravel, making the surface resistant to wear and tear over time.
Slip Resistance: The loose gravel surface provides excellent traction, making resin bonded gravel an ideal choice for areas where safety is a concern, such as driveways or pathways that are exposed to rain or snow. Its texture helps to reduce the risk of slipping.
Easy Maintenance: Once installed, resin bonded gravel requires minimal maintenance. Regular sweeping to remove debris and occasional pressure washing is typically sufficient to keep the surface looking clean and functional. Additionally, since the gravel is bonded to the resin, it is less likely to shift or wash away compared to traditional loose gravel surfaces.
Disadvantages
Surface Texture: The rougher, loose appearance of resin bonded gravel may not suit every aesthetic preference. It can also be more difficult to walk on compared to resin bound gravel, especially in areas where barefoot traffic is common.
Limited Repair Options: If a section of the surface becomes damaged or wears down, repairing resin bonded gravel can be more challenging than resin bound systems, as it may require reapplication of resin and gravel.
In summary, resin bonded gravel is a robust and visually appealing surface solution, offering a unique combination of aesthetic flexibility and functional performance, ideal for various outdoor applications.
