You should place a layer of thick landscaping fabric directly over the concrete slab and then a thin layer of leveling sand over that to protect the pavers from moisture. For border pavers, you should plan on locking them in place with polyurethane adhesive. This will prevent them from shifting under foot traffic.

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.

To adhere pavers to concrete, you can use either mortar or a concrete-specific adhesive. For border pavers, a polyurethane-based adhesive is a good choice as it expands and contracts with temperature changes, keeping them firmly in place. For the non-border pavers, polymeric sand is used between the joints to prevent shifting. In most cases, it is also recommended to lay a permeable sand layer below the pavers to ensure proper stability and drainage. Before starting, always take the proper preparatory steps for a professional result.

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.
