What Resin Is Used for Driveways?

Resin bound driveways have become a popular choice for their durability, smooth finish, and wide range of design options. The type of resin used is a key factor in how well the driveway performs and how long it lasts. Understanding the options helps you make an informed decision before installation.

The details here are based on the experience of trusted driveway installers who work with high-quality materials. You can also learn more about finishes and colour options on our resin bound driveway services page.

Key Takeaways

• Polyurethane resin is the standard for resin bound driveways.

• UV-stable resin resists yellowing and fading.

• Non-UV resin is cheaper but can discolour over time.

• The resin must be compatible with the chosen aggregate.

Types of Resin Used in Driveways

Polyurethane Resin

The most common choice for resin bound driveways is polyurethane. This resin is flexible, strong, and able to cope with temperature changes without cracking. It bonds well with aggregate stones, creating a solid, smooth surface.

Polyurethane resin is also resistant to many common chemicals, which helps the driveway stand up to fuel spills and cleaning products.

UV-Stable Resin vs. Non-UV Resin

• UV-Stable ResinDesigned to resist the effects of sunlight, this resin prevents the surface from yellowing or losing colour. It’s ideal for light-coloured aggregates or driveways that get full sun for much of the day.

• Non-UV ResinLess expensive but prone to discolouration when exposed to direct sunlight. It’s best suited for darker stone blends or shaded driveways where colour change is less noticeable.

While both types are durable, UV-stable resin offers better long-term appearance.

Resin Compatibility with Aggregates

The resin must be matched to the aggregate size and type to achieve the right strength and finish. Most resin bound systems use natural stone aggregates in sizes ranging from 1mm to 5mm. The resin coats each stone, and the mix is laid to a depth of around 15–20mm for driveways.

Curing Time and Weather Conditions

Polyurethane resin typically cures within 4–6 hours for foot traffic and around 24 hours for vehicles. Weather plays a big role in curing times — warm, dry conditions are ideal, while cold or wet weather can slow the process and affect the finish.

Why Resin Quality Matters

High-quality resin ensures the driveway stays stable, resists wear, and maintains its appearance for many years. Cheaper or low-grade resin can lead to premature wear, loose stones, or uneven colour.

Summary

Polyurethane resin is the standard choice for resin bound driveways, with UV-stable options providing the best protection against colour change. Selecting the right resin type and pairing it with suitable aggregates is essential for a strong, attractive, and long-lasting surface.
