Question 1

How to stop moss from growing between block paving?

Accepted Answer

•

After removing existing moss, consider using paver blocking sand to fill the joints. This specialty material hardens once placed and serves as an effective barrier against moss and weeds. From there on, regularly clean your pavers and try to keep them dry. You can also seal your paver as a semi-permanent solution — just make sure you reseal every 3 to 5 years.

Question 2

Is a 20% slope too steep for a driveway?

Accepted Answer

•

While some areas may allow for a slope of up to 20%, this is often the maximum slope for driveways, with a few exceptions of up to 25%. Other regions may have a maximum of 12%, 15%, or 18%, so check with your local building department to ensure you’re laying a driveway that is up to code for your location.

Question 3

Does paving or repaving a driveway increase home value?

Accepted Answer

•

Yes, a paved or repaved driveway can boost your home's value by increasing its curb appeal and the functionality of your outdoor space. A new driveway can add anywhere from $5,000 to $20,000 to a property's value. An old, crumbling driveway can be a red flag for potential buyers and inspectors.

The amount of value added depends on the materials used, the design, and local market conditions. Concrete is often cited as adding the most value due to its long lifespan, though asphalt may be more desirable in colder climates. The return on investment is greatest when replacing a driveway that is in poor condition; repaving a driveway that is already in good shape will not yield as significant an increase in value.

Question 4

Is it worth it to build a cobblestone driveway?

Accepted Answer

•

Cobblestone driveways can take a major hit on anyone's bank account, begging the question of whether it's worth it to build a cobblestone driveway. Some homeowners might prefer more affordable driveway materials like concrete or pavers, which can give a similar appearance to cobblestone without the high price tag.

Paving your driveway costs between $2,500 and $6,600, to put that in perspective. But for others, there’s nothing quite like the timeless look of cobblestone driveways.

Question 5

What’s the difference between asphalt and blacktop?

Accepted Answer

•

While blacktop is a type of asphalt, the terms should not be used interchangeably, as not all asphalt qualifies as blacktop. The primary differences are in their composition, production process, and ideal applications. Blacktop contains more stone than other types of asphalt and is heated to a higher temperature during production—300°F or more—while hot-mix asphalt is heated to between 275°F and 300°F. The ratio of bitumen (a tar-like crude oil) is a key differentiator, though sources vary: some state blacktop has less bitumen, making it less durable, while others claim it has a higher ratio. Due to these differences, asphalt is generally more durable and better for high-traffic areas like highways and streets, while blacktop is more suitable for playgrounds and residential driveways. For a driveway project, it is best to consult a professional to determine the most appropriate material.
