A paver is stone, concrete or brick that is used to lay on a flat surface to make a patio, driveway or walkway.
The best types of pavers are those that will interlock with the sand that is placed between them.
Interlocking Brick Paver
Traditionally brick pavers were manufactured in 4" x 8" by 1 ½" thick or 6" x 12" by 1 1/2" thick. But with the recent success of interlocking paving stones, many brick manufacturers are now manufacturing a brick paver that has spacers built into the sides to create a space between each paver.
As they are laid in the sand the joints between each brick are filled with sand. This works to lock the bricks in place much more effectively than placing the bricks side by side without the sand.
The bricks are very stable, and the sand between the bricks makes the surface very strong, but still flexible so as to withstand varying pressures and even earth quakes.
A brick paver that is set in sand is usually 4" x 8" by 2 3/8" thick. It is made out of clay and kiln dried. They're very strong and can test out over 12,000 PSI. They also have all the advantages of interlocking concrete paving stones; strength, crack free and affordable. The surface however is real brick. The paver’s top edges are usually beveled to prevent chipping during installation. The bevel also emphasizes and enhances the pattern in which bricks are laid.
Brick Paver Installation
This chart outlines the various pros and cons of a paving stone installation verses other options. Brick pavers are a bit more costly than concrete paving stones. They are in the $10 per square foot range. The area to be paved is excavated not just the thickness of the pavers, but enough for the bedding sand and up to 8 inches of base material. The base used is specifically made for paving stones as well as road base. The finished product has no mortar joints, only sand.
Bricks which use mortar gives a familiar, traditional appearance, yet, it can be vulnerable to cracking resulting from ground shifts below the surface. The non-mortar, sand-based technique for paving, as mentioned above, has increased in popularity in recent years, because of the ease of installation, durability, strength and cost.
With the increase in sand-based installation, brick makers are producing styles which make these installations as elegant as ones using mortar while basically eliminating the problem of edge chipping and surface cracks.
