Do you have cracked concrete in your yard? This type of asphalt paving is done in one day, with no mess or rubble, and drastically saves money on renovations
Concrete is synonymous with strength and longevity, but it is not indestructible. The ravages of time, temperature fluctuations, heavy loads, and regular winter salt use leave their mark. When the first cracks appear and the surface begins to crumble, traditional repairs with mortar or repair compounds often look messy, like poorly stitched patches, and are short-lived.
TL;DR
- Asphalt overlaying is a fast and cost-effective method for repairing cracked or worn concrete surfaces, often completed in one day.
- Benefits include significant savings on time and money by avoiding heavy machinery for demolition and waste removal, better resistance to road salt, improved aesthetics, and reduced noise and mess compared to full demolition.
- A crucial prerequisite for successful asphalt overlaying is the structural stability of the existing concrete base; otherwise, the new asphalt may crack due to underlying movement.
- Proper preparation involves thorough cleaning, repairing larger cracks, ensuring proper drainage, and applying a bonding agent (bitumen emulsion) before asphalt application.
- The required asphalt thickness varies based on the intended use, from 3-4 cm for pedestrian areas to 5-7 cm for standard vehicle traffic, and over 7 cm for industrial loads.
- Potential drawbacks include the complexity of future repairs due to the two-material system and the risk of reflective cracking if the base concrete is unstable.
- Costs typically range from 15-18 euros per square meter for basic overlaying, and 25-35 euros per square meter if significant preparatory work is needed.
- Alternatives to concrete, such as stone and decking, are also mentioned as aesthetic and functional options for outdoor spaces.
