How to Tell When Your Driveway Needs Sealing
Driveway sealing is important to get the maximum lifespan out of both asphalt and concrete driveway use. Depending on the driveway and the techniques used your driveways’ lifespan can last 5 -15 years before needing resealing. Because every driveway is different, it’s worthwhile being aware of the tell-tale signs your driveway is due for a new seal as this will help you avoid unnecessary driveway damage and costs down the track.

What Exactly is Driveway Sealing?
Sealants are traditionally applied to asphalt and concrete driveways during installation and as part of standard driveway maintenance. The process for each, sealing concrete driveways and spray sealing asphalt driveways are two very different processes. Let’s take a closer look:
Sealing a concrete driveway involves applying a thin, protective film over the concrete surface. A wide range of sealant products are available on the market, including acrylics, polyurethanes, epoxies and penetrating resins. At Asphalt Concepts we specialise in all types of concrete driveway repairs and maintenance and can advise you which sealing product will best protect your driveway.
What are the benefits of concrete driveway sealing?
- Aesthetics – It enhances the colour of the concrete and adds an appealing glossy finish without being slippery.
- Durability – It can increase the lifespan of your concrete driveway by helping prevent; water absorption, under-slab erosion (wash out) and fading from sun exposure (for coloured concrete).
- Easy Clean – It makes your driveway less porous and can actually repel stains from substances like grease and oil.
Asphalt Spray Sealing
We usually apply our asphalt spray seal as a two-coat system for new or never sealed driveways. Liquid bitumen is sprayed onto a prepared road base surface; a 14mm aggregate is then spread evenly and rolled with a rubber tyred roller. A second coat of bitumen is sprayed, followed by a layer of 7mm aggregate to fill the voids between the aggregate of the previous coat, then rolled again. The surface texture of a spray seal is coarse with an amount of loose stones on the surface. This is usually left and will bed in when driven on over time. For lighter use applications or rejuvenation of an older surface, a single coat spray seal is more likely suitable. At Asphalt Concepts we’ve been working with asphalt since 2004, so we can guarantee an expertly applied, evenly distributed non-slip seal.
Another option for spray sealing is an asphalt overlay. A layer of asphalt is applied to your driveway surface. This is a cost effective solution to freshen up the visual appeal and double the life of your driveway.
What are the benefits of asphalt driveway spray sealing?
- Durability – A spray seal can help prevent natural deterioration by creating a barrier between the asphalt and the destructive impact of water penetration
- Save Money – Asphalt can become dry, brittle and prone to cracking if left without a spray seal for too long. If you maintain your driveway, by applying spray seal and repairing cracks as soon as they are noticed, you can extend the life of your driveway, saving dollars down the track.
- Safety – Driveway spray sealing can help reduce skidding / slipping, most notably in wet weather once a driveway starts showing its age and the asphalt texture starts to smooth out.
Signs Your Driveway Needs Sealing
Just like every other aspect of your property, your driveway needs care and maintenance and that means periodic sealing. Don’t wait until the day you fall into a giant pothole while collecting the mail to take care of your driveway! So, how can you tell when driveway sealing is due?
Asphalt is due for spray sealing when it starts to show signs of surface damage. Another tip is to take a close look at the asphalt surface. If you’re able to make out the colour of the different stones within the surface, then your asphalt needs a top-up spray seal.
Checking your concrete driveway right after a downpour is an easy way to determine if it’s due for sealing. If you can see water beading on the concrete, that means the seal is still effective. If water soaks in instead, then it’s time for sealing! Alternatively, you may choose to seal based purely on the aesthetics of the concrete. If you love that high gloss look for your concrete, you can simply decide to reseal when the gloss has started to fade.
How Often Should My Driveway Get Sealed?
As with most things in life, there’s no hard and fast rule when it comes to the frequency of driveway sealing. This is because every driveway is different and experiences different traffic volumes. Importantly too, climate conditions vary so much across the country. For instance, driveway sealing in Brisbane would likely be required less frequently than in Far North Queensland, where the sun is fiercer and the rain more frequent and intense.
