How to Install Interlocking Bricks for a Patio
By using interlocking bricks for a patio, you can not only enhance the beauty of the place but also they are more durable. Interlocking bricks are a better option than the conventional concrete used for the patios. Installing the interlocking brick requires a bit of time and labor but surely the result pays off. You also have the option of creating various designs using bricks of various color and shape.
Step 1: Setup
If you are installing the interlocking bricks on an already concreted patio, you are one step ahead. If not, first you have to manage and set-up the area for installing the bricks. Outline the area you are willing to cover with the interlocking bricks and to save labor you can outline the boundary with a line of brick. When you are lining up the bricks, leave a small gap between two bricks. While you are placing the bricks try to change your design and put in whole bricks in the edge. By doing so you can save labor as otherwise later you have to cut lot of bricks for making the edge of the patio. Once the area is marked out properly, dig out the area making a depth of about 5 to 6 inches.
Step 2: Plastic Edging
Next, after digging out the area, the plastic edger is to be put on the boundary. This plastic edging forms the perimeter of the patio. The top of the edging must be made in line with the ground. The plastic edging can be nailed to the ground using tent nails.
Step 3: Bottom Layer
Once the plastic edging is done the next step is to set up the bottom layer. For the under layer the most preferred material is lime. You can use concrete, sand or any other apt material for doing this but lime is the cheapest and a very effective material for this purpose. Fill in the excavated area evenly with lime and use a metal rake if necessary, for making it smooth. Then use a cinder block or any similar thing for hammering the layer till it is hardened. This might take a bit of time and you may need to repeat it several times.
Step 4: Laying the Bricks
When the hardening of the lime is complete you can actually start the process of laying the bricks. First start from the edge, lay a few blocks of interlocking bricks on the edge and check whether they are leveled or not. Next each brick must be pounded so that the bricks do not come out later. While pounding the bricks be careful and do not break the bricks. You can use a rubber mallet for pounding the bricks and setting them tightly in place. Continue this and lay more bricks until the entire excavated area is filled. In places where a whole brick does not fit in, you can cut a brick and then place it.
Step 5: Final Touch Up
Once all the bricks are laid, check if they are all leveled. If a brick is not leveled you can remove some amount of lime from the bottom of it and then place it again.
