The layer of polymeric sand under the pavers plus the polymeric sand that gets swept into the joints between your pavers holds them in place in a few ways. For one, the gritty texture of the sand helps lock the pavers together. Polymeric sand also contains bonding agents that get activated by water. Polymeric sand will take between 24 and 48 hours to fully cure, so do not walk on your paver walkway before this time.

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.

Pavers will crack in a fire pit if they are made of the wrong materials. Be sure to use kiln-fired brick paver stones when building your backyard fire pit. You can also purchase a fire pit project kit, which will sometimes come with fire-safe pavers, to help you avoid the guessing game of buying pavers separately.

One advantage of selecting a resin bound driveway over concrete or asphalt is that homeowners have a variety of colors to choose from. Manufacturers customize aggregate materials, so customers can choose browns, golds, greens, blues, reds, and blacks. Some manufacturers also offer metallic shades.
