How to Clean & Seal Exposed Aggregate Driveways in Mandurah

Take a drive through Halls-Head, Meadow Springs, or Dawesville, and you will quickly notice that exposed aggregate and liquid limestone are the undisputed kings of Western Australian driveways. They look incredible when poured, but they have one massive flaw: they trap absolutely everything.

Because the surface is highly textured and porous, your driveway acts like a giant sponge for motor oil, hot rubber from your tyres, red dirt, and black mould. Before you know it, that premium million-dollar curb appeal starts looking neglected.

The DIY Gurney Mistake ("Tiger Striping")

When the driveway gets dirty, most homeowners grab an electric pressure washer from Bunnings and spend their entire Sunday blasting away with the standard wand. Unfortunately, this usually results in a driveway covered in permanent "tiger stripes" (squiggly, uneven clean lines).

Worse, holding a high-pressure wand too close to exposed aggregate can actually blast the decorative pebbles right out of the concrete matrix, leaving bald patches. If you have deep oil stains or bore rust, cold water from a standard hose won't even make a dent.

The Peel Soft Wash Driveway Restoration Process

To bring a driveway back to life without damaging it, you need commercial-grade equipment and the right chemical treatments. Our Driveway & Concrete Cleaning service is built specifically for WA conditions:

1. Chemical Pre-Treatment: We start by applying a heavy-duty degreaser to lift embedded engine oil, and a specialized bio-wash to kill the black mould spores hiding between the pebbles.
2. Rotary Surface Cleaning: Instead of a wand, we use a commercial rotary surface cleaner. This hovering disc applies a perfectly even, consistent spray across a wide area, eliminating tiger stripes entirely and protecting the aggregate from getting dislodged.
3. High-Volume Flush: Once the dirt and oil are lifted, we flush the entire driveway down, washing the slurry straight into the drains and leaving the concrete perfectly clean.

Why You MUST Seal Your Driveway Afterwards

Once you have invested in getting your driveway professionally cleaned, leaving it raw is a massive mistake. As soon as you park your car on it again, the oil and tyre marks will instantly sink back into the open pores.

Applying a premium Concrete Sealer is the ultimate protective shield. A high-quality solvent or water-based sealer acts like a raincoat for your driveway. It locks out moisture, stops black mould from growing, and prevents oil from penetrating—meaning next time your car leaks, you can literally wipe it up with a rag.
