How to Prepare Your Existing Driveway for a Resin Bound Overlay

Introduction: Transforming your existing driveway with a resin bound overlay is a fantastic way to achieve a durable and visually stunning surface without requiring a complete driveway replacement. However, proper preparation is crucial to ensure the success and longevity of the overlay. In this blog post, we’ll guide you through the steps to prepare your existing driveway for a resin bound overlay, allowing you to achieve a seamless and attractive result.

1. Evaluate the Existing Driveway

Before beginning the preparation process, assess the condition of your existing driveway. Look for any cracks, potholes, or areas of unevenness. Addressing these issues before proceeding with the overlay is essential to ensure a smooth and long-lasting finish.

2. Repair Cracks and Potholes

If you find any cracks or potholes, it’s crucial to repair them. Here’s how:

Clean the Damaged Area: Remove loose debris, dirt, or weeds from the cracks or potholes.

Fill Cracks: Use a suitable crack filler or resin to fill in the cracks. Ensure the filler is level with the surrounding surface and allow it to dry completely.

Pothole Repair: For potholes, fill the depression with a suitable base material (like MOT Type 1) and compact it thoroughly. Top it off with a layer of the resin-bound mixture before continuing.

3. Clean the Surface Thoroughly

A clean surface is essential for proper adhesion of the resin bound overlay. Here’s how to clean your existing driveway:

Pressure Washing: Use a pressure washer to remove dirt, debris, oil stains, and other contaminants from the surface. Ensure that the driveway is completely dry before proceeding.

Weed Removal: Inspect the driveway for any weeds or vegetation growing through cracks or joints. Remove them, including their roots, to prevent future growth.

4. Surface Primer

Applying a surface primer may sometimes be necessary to improve adhesion. Your installer will assess whether a primer is required based on the condition of your existing driveway.

5. Set the Edge Restraints

Edge restraints, such as aluminium or plastic edging, are essential to contain the resin-bound overlay and prevent it from spreading beyond the designated area. Install edge restraints securely along the perimeter of your driveway.

6. Install a Suitable Base Layer

To ensure a stable and level surface for the resin bound overlay, consider adding a base layer of MOT Type 1 or crushed stone. This layer should be compacted to create a firm foundation.

7. Edge Detailing

Pay close attention to the edges, and any intricate detailing required around features like manhole covers or drainage. Properly finished edges enhance the overall aesthetics and functionality of the overlay.

8. Surface Primer (If Necessary)

Applying a surface primer may sometimes be necessary to improve adhesion. Your installer will assess whether a primer is required based on the condition of your existing driveway.

Conclusion: Preparing your existing driveway for a resin bound overlay is crucial in achieving a stunning and long-lasting result. By assessing and repairing any cracks or potholes, thoroughly cleaning the surface, installing edge restraints, and considering a base layer, you can ensure that the overlay adheres properly and creates a beautiful and functional driveway.
