Ditch Asphalt: A More Durable Alternative To Use On Your Driveway

Asphalt is perhaps the most common material used for driveways across the U.S. It is comparatively affordable and can be laid relatively quickly. The surface requires little maintenance, and even when it ages, there are ways to make your driveway look new again. However, asphalt driveways are a bit plain, and while they are reasonably hard-wearing, there is a more durable and visually interesting alternative. It is called exposed aggregate.

An exposed aggregate driveway starts out as poured concrete, then aggregates (usually smooth stones or pebbles) are added to the mix. Before it is completely hardened, some of the top surface of the concrete is removed with a high-pressure washer and a broom. This exposes the aggregates, and hence the name. Finally, the surface is polished, and a sealer is applied.

There are a number of driveway materials that go beyond concrete, but exposed aggregates take advantage of the inherent strength of that material and add a number of positive features. The aggregates come in a variety of shapes and colors, allowing the driveway to be customized to suit your home. The finished surface is slip-resistant and easy to look after. It is also more durable than asphalt, with a typical lifespan of 30 years plus, depending on the environment.

Installing an exposed aggregate driveway demands skills that are beyond the vast majority of DIYers. To be fair, the same is true of asphalt. Nevertheless, costs are significantly higher. Asphalt can be anywhere from $4 to $8 per square foot, whereas exposed aggregates are likely to be $8 to $14. Although it provides good traction when wet, removing snow can be challenging, and it's not as comfortable as a flat driveway if you're wearing thin-soled shoes or if your kids tend to run around with bare feet.

Although maintenance demands are low, an exposed aggregate driveway should be resealed every 2 to 3 years to maximize its durability. The uneven texture makes this a little more time-consuming than with a standard asphalt or concrete driveway. If you're looking for a regular surface and the consistent color of concrete or pavers, exposed aggregates will not be your best choice.

On the other hand, when you're thinking about creative ways to increase your home's curb appeal, there's no better place to start than with your driveway. The unique and stylish look of exposed aggregates makes an instant impact, and the excellent durability means it should still be looking just as good many years from now.
