Summer is here. The sun is out. You’re actually outside now, instead of huddled behind curtains pretending the gray skies don’t exist. It feels nice, right? Fresh air. Better mood. But there is a downside to spending time outdoors.
You see things you ignored in the winter. Specifically, your driveway.
It might not look as pristine as the magazine photos promised. Driveways take a beating. Cars park on them. Weather beats on them. Heatwaves bake them. If you want the front of your house to look decent—and you do—you have to fix it before it falls apart. Winter broke them with freeze-thaw cycles; summer is going to break them with heat and dry rot.
So what does broken actually look like? I asked the pros. They told me exactly where to look.
Soft Spots Are Not Cool
Tarmac should be hard. If it’s getting soft, something is wrong.
Sue Taylor from Complete Construction Products says high temperatures react badly with the bitumen binder holding tarmac together. It gets flexible. It gets tacky.
You’ll know it’s happening if you see tire marks left in the driveway after the car moves. Or indentations. It feels sticky underfoot on older drives because the material has lost strength over time. You can’t really undo softening once it happens, though. You can only stop it from getting worse by sealing the surface quickly. Don’t wait for the heat to melt it entirely.
Cracks Tell a Story
Small hairline cracks are normal. Life happens. But a crack that widens? That’s a warning shot.
Sue says timing is key here. If the crack is tiny, seal it. If it’s 5-10mm or bigger, use a proper tarmac filler. Clear out the dirt first. Fill it. Smooth it. Easy enough.
But Freya Chapman at Mainmark UK warns about something scarier. Sudden, widening cracks often mean the ground underneath is moving.
Subsidence. It’s ugly, expensive, and easily ignored until the foundation crumbles. If cracks appear out of nowhere and get worse fast, stop DIY-ing. Call a pro. It could be shifting ground, not just bad paving.
The Sinking Patch
Has your driveway developed a dip? A rut where you park your car?
That’s rutting. It happens when repeated weight hits a spot that’s already weakened by age and heat. Sue Taylor notes it’s common in older drives during summer months because the binder softens under pressure. If you park in the same spot every day, that’s your spot. The surface bends, then sinks, then stays that way.
Minor rutting can be patched. Severe cases need a full resurface. But here is the tricky part.
If you have widespread cracking plus sinking plus deep holes, patching it yourself won’t help. The problem is structural. You need experts. Trying to fix deep structural failure with a bucket of sealant is a waste of time.
Loose Bits Mean It’s Falling Apart
Tarmac, block pavers, resin. Doesn’t matter which. If chunks of aggregate are chipping off the edge, the binder is dying.
Sue explains this means the glue holding the stone or blocks together is breaking down. Catch it early and a surface treatment might save you. Ignore it? The driveway will disintegrate. Then you aren’t doing repairs; you are doing a total rebuild. Resurfacing is cheaper than rebuilding, so pay attention when the pieces start coming loose.
Is It Subsidence?
Freya Chapman points out that driveways are the first place ground movement shows up. Beyond cracks, watch for:
- Patches sinking unexpectedly
- Paving becoming uneven
- Water pooling on the drive (it should drain away)
- Gaps forming between the driveway and your garage or fence
Take photos. Measure the cracks. Note if they grow.
Water is usually the villain. Leaking drains. Tree roots sucking moisture out of the soil. Water running toward the house instead of away from it. If the ground shrinks, the house tilts. A professional assessment is non-negotiable here. Don’t guess.
Should You Do It Yourself?
Maybe. For the small stuff.
Daniel Wickham says you can pull weeds or re-sand joints on block paving yourself. Fine. Sue Taylor agrees that small, localized cracks and patch repairs are fair game for a weekend DIYer. Buy the right products. Prep the surface well.
But if it’s soft. If it’s sinking. If it’s widespread cracking?
Stay away. Let the qualified professionals handle instability. Saving a few hundred pounds now won’t help you much when you’re paying ten thousand later for a structural repair you delayed.
What are you waiting for to look?
