Looking for a pothole repair company in Perth?
Potholes are usually created when moisture penetrates into cracks of an asphalt surface on a road, car park or driveway.
Pothole repairs sometimes become necessary during the lifespan of the asphalt surface (which can be up to 20 years). The ideal time to act is sooner than you might think – when the old surface starts to crack or deteriorate.
When this happens, it allows water to pond on the surface and slowly penetrate through the cracks. The water forms in the sub-base below the asphalt surface and expands, pushing the asphalt pavement upwards.
With traffic, the pavement will then break down and collapse into the void, which becomes a pothole. Over time, and with increased use, the pothole becomes larger as the edges of the asphalt break away.
