What are the Differences Between Asphalt Paving and Seal Coating_Preparing a surface that is able to stand up to harsh outdoor elements can be rather challenging and technology has offered a number of innovative solutions. Whether referring to driveways, walkways or large parking lots, two of the most common methods are asphalt paving and seal coating.

While both might appear similar at first glance, there are actually a number of interesting differences to keep in mind. Knowing the unique characteristics of each will allow you to make the right choice when contacting professional paving contractors.

Asphalt Paving

Tarmac contractors in Cardiff will often employ asphalt paving when completely covering an existing surface or when dealing with extensive potholes. Asphalt is a viscous material which is applied directly to materials such as concrete, gravel or even existing asphalt.

Offered in hot and cold formulations, the main benefit is that it provides a robust level of protection that can last for years if cared for properly. The thickness of the asphalt will vary depending upon the needs of the location in question.

This mixture of gravel and tarmac is also waterproof and highly durable; offering an extremely hard-wearing surface.

Seal Coating

Seal coating is a rather inexpensive process that helps to extend the lifespan of underlying material such as concrete or asphalt. This liquid coating is rolled or painted over the area and once allowed to cure, it effectively seals (hence the name) the material from potential exterior damage.

Seal coating is often used when addressing car park surfacing maintenance tasks and other one-off issues. Seal coating will also help to safeguard the underlying surface from excessive oxidation; once again extending is aggregate lifespan.

Both of these methods are highly effective and when performed by professionals, they offer a resilient surface that is able to stand up to a plethora of weather conditions. This is why it is best to work with a trained firm, as the results are guaranteed and the majority of projects will be completed within a short period of time.
