Install Resin Bonded Gravel

If you're looking to enhance your outdoor space with a stylish and durable surface, resin bonded gravel might be the perfect choice. This innovative paving solution combines the beauty of natural gravel with the strength of resin, creating a smooth and attractive finish that can transform driveways, pathways, and patios. Not only does it offer a unique aesthetic, but it’s also low maintenance and permeable, making it an eco-friendly option.

Overview of Resin Bonded Gravel

Resin bonded gravel is a distinctive surfacing method that combines resin with aggregate stones. This process involves applying a resin layer to a prepared base and scattering aggregate stones over it. The resin serves as an adhesive, securing the stones in place while allowing them to remain partially exposed, resulting in a textured, non-permeable surface.

Types of Resin Surfacing

• Resin Bonded Gravel: Utilizes a resin layer for stone adhesion, leading to a durable but non-porous finish.
• Resin Bound Gravel: Blends resin with aggregate stones before application, creating a smooth, permeable surface that complies with Sustainable Urban Drainage Systems (SUDS) standards.

Installation Steps for Resin Bonded Gravel

• Confirm that the base surface (concrete, block paving, or slabs) can support the desired traffic load. Proper preparation ensures the longevity and performance of the resin bonded gravel installation.

Benefits of Resin Bonded Gravel

Resin bonded gravel offers numerous advantages that make it a top choice for outdoor surfacing. From its aesthetic qualities to its resilience, this paving solution enhances various outdoor spaces effectively.

Aesthetic Appeal

Resin bonded gravel provides a unique and attractive finish, combining the natural charm of gravel with modern resin technology. Available in various colors and textures, it allows customization to complement existing landscapes. The finished surface appears smooth and inviting, making it suitable for driveways, pathways, and patios.

Durability and Longevity

Resin bonded gravel boasts impressive durability, capable of withstanding various weather conditions and heavy traffic loads. The resin binds the aggregate stones securely, preventing displacement and degradation over time. This combination of materials provides a long-lasting solution that resists cracking, chipping, and fading, ensuring consistent performance for years.

Low Maintenance Requirements

Resin bonded gravel requires minimal maintenance compared to traditional gravel surfaces. It's easy to clean, often just needing occasional sweeping to remove debris. The non-porous nature helps prevent weed growth, reducing the need for herbicides. Regular inspections and simple touch-ups keep the surface looking pristine without significant effort.

Preparation for Installation

Preparing for the installation of resin bonded gravel involves careful planning and material selection. This ensures a durable and visually appealing surface.

Choosing the Right Materials

Select high-quality resin and aggregate materials for optimal results. Look for resins specifically designed for gravel applications to ensure proper bonding and durability. Choose aggregate stones that complement your aesthetic preferences, keeping in mind color, texture, and size. Opt for aggregates that are round and angular for improved stability and traction.

Site Assessment and Preparation

Assess the existing site to determine its suitability for resin bonded gravel. Check the base surface for any cracks or damage; if it's not strong enough, consider excavating and installing a new base. Ensure the area is dry and free from dust, weeds, and algae; thorough sweeping is essential before starting the installation.

Prepare the base to support the resin surface effectively. For new installations, a sub-base of at least 150mm of MOT type 1 material is recommended, compacted with a vibrating roller. Over this, apply either a 125mm thick concrete layer or a 75mm thick base coat tarmac layer. Fix the edgings in position with sharp sand and cement, ensuring they are 15-20mm proud of the finished sub-base.

Step-by-Step Installation Process

Installing a resin bonded gravel surface involves a few straightforward steps. Carefully following this guide ensures a durable and visually appealing finish for your outdoor space.

Applying the Resin

Prepare the resin by mixing the components of Part A and Part B in a separate container using a powerful drill and paddle. Mix until the color is uniform, typically requiring 60-90 seconds. For specific kits, mix slowly for about 20 seconds in a rubber container before combining the components. Once mixed, pour the resin onto the prepared base, spreading it evenly with a trowel or roller. Aim for a consistent layer that ensures proper bonding with the aggregate.

Spreading the Gravel

After applying the resin, immediately scatter the aggregate stones over the surface while the resin remains tacky. Use a shovel or broadcasting tool to achieve an even distribution. Ensure full coverage, so the aggregate adheres to the resin without any visible gaps. The thickness of the aggregate layer should typically be around 10-15mm, ensuring a robust and textured finish.

Finishing Touches

Once the aggregate is spread and has set for the recommended time, gently brush off any excess gravel with a broom. This step enhances the aesthetic and ensures an even surface appearance. Allow the resin to cure for at least 24 hours before subjecting the area to foot or vehicular traffic. You might consider applying a sealant after full curing to increase durability and resist staining.

Common Mistakes to Avoid

Inadequate Base Preparation

• Ensure the base is strong enough for the intended use. Repair any cracks or damage before proceeding with the installation[1][3][5].
• Make sure the surface is dry and free from dust, weeds, and other debris. Priming the surface with an appropriate primer enhances adhesion[1][2][5].

• Mix the resin components (Part A and Part B) thoroughly and accurately. Short mixing times or incorrect ratios lead to poor adhesion and uneven curing[2][3][5].
• Ensure all aggregate is evenly coated with the resin. Uniform mixing maintains color consistency and prevents dry spots in the finished surface[1][3][5].

Conclusion

Choosing resin bonded gravel for your outdoor spaces can transform your driveways and pathways into stunning features. Its blend of durability and aesthetic appeal means you'll enjoy a beautiful surface that stands the test of time.

By following the proper installation steps and avoiding common pitfalls, you can ensure a long-lasting finish that requires minimal maintenance. With various colors and textures available, you can easily customize your space to match your style.

How does resin bonded gravel differ from resin bound gravel?

Resin bonded gravel creates a durable, non-porous surface, while resin bound gravel is smooth and permeable. The latter allows for water drainage, complying with Sustainable Urban Drainage Systems (SUDS) standards, making it suitable for areas where water management is crucial.

What are the benefits of using resin bonded gravel?

Some benefits of resin bonded gravel include its aesthetic appeal, durability, low maintenance requirements, and customization options. It withstands various weather conditions and heavy traffic loads without cracking, and its maintenance typically only involves occasional sweeping.

How do you prepare for resin bonded gravel installation?

Preparation includes selecting high-quality resin and aggregate materials, assessing the site for suitability, and ensuring a stable base. A sub-base of at least 150mm of MOT type 1 material should be compacted, and edges should be properly fixed for optimal results.

What is the installation process for resin bonded gravel?

Installation starts with mixing the resin components thoroughly. After applying the resin evenly to the base, aggregate stones are scattered on top while the resin is still tacky. The surface is finished by brushing off excess gravel, and the area is allowed to cure for 24 hours before use.

What mistakes should be avoided during installation?

Common mistakes include inadequate base preparation, improper mixing of resin components, and uneven coating of stones. Ensuring the base is dry and clean, using correct mixing ratios, and achieving uniform coverage are essential to avoid problems and ensure a long-lasting surface.
