Main Reasons Cracks May Develop On Your Driveways

Installing a driveway at home is something some people don’t put much emphasis on. In fact, some people say that driveways are only good for people with cars. This is not always true since driveways also boost the aesthetic value of a home. People install driveways for different reasons using different materials.

Moisture

Water infiltrates in any paved surface and this does not go well with the driveway. This infiltration could eventually wash away the sand and gravel base of any asphalt driveway.

A single crack is enough to cause this flexibility loss. The presence of cracks on your driveway means you need to contact experts who offer quality asphalt repairs Melbourne has today.

Sun

The sun causes some of the substances to destabilize in the asphalt mixture due to the heat it produces. The sun heat causes the asphalt to dry out quickly and this finally causes it to break down and wear out. What keeps asphalt in good condition is moisture. If there is not enough moisture, the asphalt will wear down and form cracks on it. When the sun is too hot, the asphalt ingredients break apart and this may lead to expensive repairs if one is not careful. It is important to note that heavy foot traffic and parked cars cause cracking in many of the driveways Melbourne has in homes.

Ground movements

Conditions such as frost and thaw as well as other seasonal changes cause the ground to constantly shift. The ground or earth could also shift due to certain natural disasters. What you need to know is that the impact from the annual ground movement is great and it puts much pressure on the asphalt causing potholes and cracks.
