Depending on installation and materials quality, how often the walkway is used, and the climate you live in, your brick paver walkway could last 25 to 50 years before it needs replacement or major repair.
Considering that the cost of a concrete walkway is typically $6 to $12 per square foot and the cost of a brick path is typically $8 to $19 per square foot, it’s cheaper to lay poured concrete than build with bricks.
Assuming that you’re using typical 4-by-8-inch bricks, it takes 4 1/2 bricks to cover one square foot. To determine how many paver bricks you need, figure out the measurements of your walkway to get the square footage, and then multiply that number by 4 1/2.
A standard walkway measures 36 inches wide. If you want to build one where two people can comfortably walk side by side, you should expand yours to 48 inches wide.
If you’re building a brick sidewalk with straight lines, the process isn’t quick, but it’s not particularly difficult. However, things start to get tricky when you opt for a walkway with curves. To accomplish the perfect bends, you’ll often need specialty brick pavers or a wet saw to cut typical bricks to size.
