Do you want to replace your outdated concrete patio or driveway with a more beautiful design? Perhaps you are wondering if laying pavers over the concrete already in place is possible. Here you have a typical question, and the answer will help you make your project less complicated and cheaper. I will explain the procedure to you and let you know if this option is suitable for you.
Can You Install Pavers Over Old Concrete?
Yes, it is possible to lay pavers over concrete and this is the best way to go especially if the concrete is old. This method also has the advantage of being time and cost-efficient. It is not necessary to demolish the old concrete which is always a time-consuming process. However, you can use it as the foundation for your new pavers instead of being a hindrance. However, you should ensure that the existing concrete is in good condition before you apply the above methods. It should not have large cracks or any other major damage on it.
Why Choose Pavers?
Pavers are widely used in the construction of outdoor flooring. They are available in different styles and colors and this can complement the appearance of your room. Pavers are also strong and can easily handle traffic, especially heavy ones. When you place them on concrete, you are provided with a hard and firm ground to work on.
Preparing the Old Concrete
First of all, it is necessary to assess the state of the old concrete before beginning the work. Wash it to ensure that it is free from dust and any other form of dirt. If there are small cracks, then you can apply a concrete patch on those areas as well. For bigger cracks or if the surface is irregular, you may have to call a professional. It is very important that the old concrete is free from debris and also that the surface is flat before proceeding with the paver installation.
Choosing the Right Pavers
Choose pavers that you like and that will meet your requirements. Think about the thickness of the pavers. Thicker pavers are ideal for the driveway or any other region that is bound to experience a lot of traffic. If the area to be paved is a patio or a walkway, then the pavers used have to be thinner. Ensure that the kind of pavers you select are suitable for installation over concrete. There are some pavers that have special features that enable them to be laid on a rigid base.
Installing the Pavers
Now, let’s go to the installation process. First, apply a thin layer of sand or mortar over the old concrete to ensure that the new concrete will stick well to the old one. This layer also assists in creating a flat surface and also helps in the stabilization of the pavers. It is advisable to start laying the pavers from one corner of the area and spread out to the other corner. Lay each paver properly to guarantee that it is in the right position, level with the other and touching it. If necessary, tap them into place with a rubber mallet.
Securing the Edges
There are certain restrictions that are needed at the edge to ensure that the pavers do not move. Place edge restraints at the periphery of the area. These can be plastic, metal or concrete strips that lock the pavers into position. If edge restraints are not used, the pavers can move and thus lead to formation of gaps.
Filling the Gaps
After all the pavers are laid down, ensure that there is sand in between the pavers to help in interlocking. Sweep the sand into the joints using a broom. This step is very important as it ensures that the pavers are interlocked and cannot move from their positions. After filling the gaps, use a plate compactor to level the pavers and sand down. Continue with the sanding and compacting until the gaps are filled to the required level.
Maintaining Your Paver Surface
It is important to ensure that your paver surface is well maintained to ensure it always looks great. Clean the area daily by sweeping it to ensure that it is free from dust and other particles. Sometimes, it is required to introduce additional sand into the joints. If you find some of the pavers moving or becoming slightly loose, then it is advisable to fix the problem before it worsens.
Benefits of Pavers Over Concrete
Plain concrete has the following disadvantages which are however not characteristic of pavers: They are more attractive and may add value to your property. Pavers are also more flexible, and therefore if there is a need to repair some part of the pavement, it can be done easily. Pavers on the other hand can crack and they can be replaced one at a time unlike concrete which is a solid slab.
Potential Challenges
However, there are some difficulties in installing pavers over concrete which is advantageous in some ways. If the old concrete is not flat, it might be challenging to level it. Also, if the concrete has major cracks or structural problems, then it may not be ideal for paver installation. It is always important to evaluate the state of the existing concrete before beginning the project.
