Calculating the Amount of Dried Aggregates

To calculate the number of dried aggregates needed for resin-bound installation, you can follow these steps:

Determine the Area: Measure the length and width of the area where the resin-bound surface will be installed. Multiply these two dimensions to obtain the total square meters or square feet area.

Determine the Desired Thickness: Decide on the desired thickness of the resin-bound surface. The typical thickness ranges from 15mm to 18mm (0.6 to 0.7 inches).

Calculate the Volume: Multiply the area by the desired thickness to obtain the resin-bound material needed in cubic meters or cubic feet.

Convert Volume to Weight: Aggregates are usually sold by weight, so you must convert the volume to weight. You’ll need to know the bulk density of the aggregates you plan to use to do this. The supplier typically provides the bulk density, expressed in kilograms per cubic meter (kg/m³) or pounds per cubic foot (lb/ft³).

Use the Conversion Factor: Multiply the volume by the bulk density to convert the volume to weight. The result will give you the total weight of the dried aggregates required for the resin-bound installation.

It’s important to note that the specific mix design and aggregate selection may vary depending on the manufacturer’s recommendations and the desired properties of the resin-bound surface. It is advisable to consult with a supplier or professional installer who can provide accurate calculations based on your project’s specific materials and requirements.

Necessary Equipment

To carry out a resin-bound driveway installation, you will need the following materials and equipment:

Dried Aggregates: Choose a selection of aggregates in various sizes and colours to achieve the desired aesthetic for the driveway.

Resin: Select UV-resistant resins specifically designed for external applications like resin-bound driveways to ensure durability and colour stability over time.

Forced Action Mixer: Use a reliable forced action mixer, such as the Baron F110, with a capacity suitable for the recommended mix design.

What to Consider Before Installation?

Before starting the installation of a resin driveway, it is essential to consider the following factors:

Surface Suitability: Assess if the existing surface is suitable for a resin-bound installation. The surface should be structurally sound and capable of supporting vehicles’ weight and traffic load.

Base Stability: Ensure that the base layer is stable and adequately prepared. The base should be free from any soft spots or areas prone to subsidence and provide a solid foundation for the resin-bound surface.

Surface Cracks: Inspect the surface for any existing cracks. Significant cracks may need to be repaired or filled before the resin-bound installation. It is crucial to address any underlying issues to prevent the cracks from reappearing and affecting the integrity of the resin surface.

Surface Damage: Check for any damage to the surface, such as potholes, depressions, or uneven areas. These should be repaired or levelled before proceeding with the resin-bound installation to ensure a smooth and uniform finish.

Considering these considerations before starting the installation process will help ensure a successful and long-lasting resin driveway. It is advisable to consult with a professional installer or contractor who can assess the surface’s suitability and provide guidance on any necessary repairs or preparations.

Pre-Installation Preparations

Preparation is a crucial part of installing a resin-bound surface. Here are some of the key steps involved in preparing the area for installation:

Site Survey: Conduct a thorough site survey to assess the area and identify potential obstacles, such as drainage systems, trees, or existing structures.

Site Clearance: Clear the area of any debris, vegetation, or other materials that may interfere with the installation process.

Base Preparation: Prepare the base by excavating the area to the required depth and laying a suitable base layer. The base layer should be free from any soft spots or areas prone to subsidence and provide a solid foundation for the resin-bound surface.

Edge Restraint Installation: Install edge restraints along the perimeter to prevent the resin-bound surface from spreading beyond the designated area. The edge restraint should be made of suitable steel, aluminium, or plastic.

Surface Cleaning: Clean the surface thoroughly to remove any dirt, oil, or other contaminants that may affect the adhesion of the resin-bound material. A power washer or industrial cleaner may be used for this purpose.

Surface Levelling: Ensure the surface is level and free from any bumps or depressions affecting the finished surface.

Primer Application: Apply a primer to the surface to improve the adhesion of the resin-bound material. The primer should be chosen based on the specific substrate and resin system used.

These steps will adequately prepare the area for the resin-bound installation, ensuring a smooth and long-lasting surface. It is advisable to consult with a professional installer or contractor who can provide guidance and assistance throughout the preparation process.

Appropriate Bases for A Resin Driveway

Following are some suitable bases for a resin driveway:

Macadam: Macadam, or tarmac, is a commonly used base for resin driveways, and it provides a stable foundation and is compatible with the resin-bound system.

Asphalt: Asphalt is another suitable base option for a resin driveway, and it offers excellent durability and stability, making it a popular driveway choice.

Concrete: Concrete is a versatile and durable base material that works well with resin-bound systems. It provides a solid and long-lasting foundation for the resin driveway.

These bases offer stability, load-bearing capacity, and compatibility with resin-bound systems. When installing a resin driveway, assessing the project’s specific requirements and consulting with professionals to determine the most suitable base material based on factors such as the expected load, site conditions, and local regulations is essential.

Steps for Mixing the Resin

To mix the resin for a successful installation of a resin-bound system, follow these steps:

  • Follow precise blends for resin and aggregates to meet site requirements.
  • Use a protective surface for resin mixing to prevent splashes.
  • Secure the resin container before starting the mixing process.
  • Mix Part A components slowly for 10-20 seconds with a high-torque mixer.
  • Add Part B component and mix thoroughly for around 60 seconds until uniform.

Maintaining accuracy and precision during the mixing process is crucial to ensure the desired properties and performance of the resin-bound system. If multiple batches are required for the project, it is important to use the same batch in one area to avoid slight variations between batches.

Managing the curing speed

  1. Let the surface cure for 8 hours, but hold off on foot traffic for 24 hours.
  2. Add an accelerator (also called a catalyst) to maintain curing speed.
  3. Use the accelerator for temperatures below 15°C, especially overnight.
  4. Ensure uniformity by using the accelerator in each mix.
  5. Remember, you may skip the accelerator at consistent temperatures of 25°C.

Calculating the Amount of Catalyst

The amount of accelerator (catalyst) required depends on your specific resin and accelerator. Follow the manufacturer’s instructions for the recommended mixing ratio. Typically, mix Part A of the resin for 15-20 seconds before adding the specified amount of accelerator (Part B). Thoroughly blend the mixture to ensure even distribution of the catalyst before proceeding.

Making A Mixture of Sand, Resin and Aggregates

  • Place a 25kg bag of 2-5mm aggregates and a 25kg bag of 1-3mm aggregates in the mixer.
  • Add pre-mixed resin and start the stopwatch.
  • Add two more 25kg bags of 2-5mm aggregates.
  • Slowly add the bag of C52 sand.

Here are some key tips to keep in mind:

  1. Dry aggregates only! Avoid dampness before mixing.
  2. Mix thoroughly to coat all materials evenly.
  3. Time matters! Ensure consistent duration for each mix.
  4. Use the right blend of aggregates for optimal results.
  5. Keep aggregates shaded to maintain their quality.

Supplying Material at the Required Workplace

Teamwork and precision are key during the installation process:

  • The luter transfers the mix to the troweller’s area.
  • Tip manageable amounts of the mix, ensuring even distribution. Avoid excess material to minimise trowelling.
  • Scrutinise the trowelled surface from different angles. Address any imperfections promptly, as they become harder to fix once the mix has cured.

Trowelling the Mixed Material

Following are the key points to trowel the material for a resin driveway:

  • Plan the route and mark the area with chalk squares.
  • Use batons as guides for tipping the mix.
  • Consider using a screed bar for a smoother surface before trowelling.
  • Keep the trowel clean with white spirit and clean it regularly.
  • Pack aggregates tightly into edges to eliminate gaps.
  • Knit the mix together, maintaining pressure but preventing trowel digging.
  • Trowel until aggregates settle and become solid, using minimal strokes.
  • Polish the surface for an appealing sheen.
  • Leave the edges rough for seamless blending of the next batch.
  • Enhance slip resistance with a light sprinkling of crushed glass.

Ensure Proper Compaction and Depth Consistency

In the last, for a quick check of mix compactness and trowelling depth you should:

  • Cut a section into the edge of the trowelled surface.
  • If it stays intact, the mix is adequately compacted and knitted.
  • This test also ensures your trowelling depth is accurate and consistent.
