These are general instructions for the installation of paving brick. Every project and situation is different and therefore, may require modifications or changes in the installation procedures. Before you begin your project, you should always check on local building codes (permits maybe needed and restrictions may apply), call J.U.L.I.E. at 1-800-892-0123 in Illinois to locate in-ground utilities, and refer to the manufacturer’s installation and reference documentation for the brick you plan to install. Large projects or load-bearing structures such as driveways, should be installed by a professional, because of the drainage and supporting foundations needed. We can recommend professional installers for your project.
Why Paving Brick?
There are several very good reasons to use paving brick
for your walk or patio other then its beauty and functionality. First, we
live in an environment that has freezing and thawing. When the ground freezes,
it expands and will move and heave your walk or patio. Solid structures
like poured concrete will tilt or crack, leaving damage that is difficult
if not impossible to repair. Paving brick float on their gravel base, as
the ground freezes and expands, the individual brick can move upwards with
no damage. When spring arrives and the ground thaws, the brick settle back
into place with no cracks or breakage.
Secondly, most walks and patios are near the foundation of your house. When the house was built, this area was dug-up and then back-filled. The material in the refilled area will settle and this settling can continue for years and years. Depending on the amount and depth of the excavation that was done during the construction of your house, this settling can continue for up to 50 years. Like stated before, paving brick are not a fixed structure and can move when the ground moves. This makes paving brick idea to use in areas that may settle. If settling occurs, the brick can be removed in the afflicted area, the base material filled and leveled, and the brick returned, a simple fix that restores the beauty and functionality of your walk or patio.
Lastly, paving brick are not a permanent structure. This means that they can be moved or removed. As time passes, your needs or desires can change. Maybe you need a bigger patio, or a smaller one. Perhaps the tree next to your sidewalk has grown too big. Either you cut down the tree or just move the sidewalk. With paving brick, this is possible. Your walk or patio can be altered just by moving the brick.
The most important part of any project is the base. This supports your walk, drive or patio and anything that is placed on it. If your base fails, your brick project fails. Typically the base of any hardscape project consists of a crushed gravel topped by a leveling sand. In the case of paving brick, the gravel used is a ¾” crushed limestone, ranging from ¾” stone to dust size particles. The particles, called “fines,” filter into the gaps between the stone creating a hard, solid surface. A thin layer of leveling sand is then placed over the compacted stone to smooth out the gravel and provide a level surface to place the brick on.
