How to Replace Concrete Patio Pavers
Concrete patio pavers are common for outdoor flooring areas since they are long-lasting and require little upkeep. However, there might still be cases where one or more of the pavers need to be replaced. In such cases, it will be worthwhile to know how to replace them yourself, rather than having to hire somebody else. Follow the simple steps below to effectively replace concrete pavers on your own.
Step 1: Determining the Setting
Start off by determining whether your concrete pavers are set in a foundation of mortar or sand. This will directly affect the way you will replace the pavers. Before you move on, put on gloves to protect your hands.
Step 2: Remove the Concrete Pavers
Start removing the particular paver or pavers with a pry bar. If you can not manage to remove them this way, you might have to use a mason's hammer.
Step 3: Cleaning the Gap
If the paver is set in mortar, use a chisel to remove any remaining mortar in the area below and from the sides. On the other hand, if the paver was embedded in sand, clean away any sand that has any residues stuck with it.
Step 4: Preparing and Filling the Gap
Next, you have to prepare the gap so it will be a good foundation for the new paver. If your pavers are set in sand, spray water onto the exposed area and tamp down the sand. Then, fill the gap with a new layer of sand, and spray with some more water. Smooth it down and repeat until the layer is slightly above the other pavers' levels.
If the pavers are set in a foundation of mortar, you have to mix some dry premixed mortar with water until you get the right consistency. Then, start using this mixture to fill in the gap where the new paver will be placed. Smooth it using a piece of wood.
Step 5: Placing the New Concrete Pavers
Once the gap has been properly prepared, you can start to place the new pavers in place. Make sure they are of the correct size, and start off at a corner. If the pavers need to be cut, use chalk to mark the part that has to be removed. Then put on safety glasses, and use a mason's hammer to tap and strike the area until you manage to remove the excess part. When done, press the paver downwards so that it fits in snuggly, and check whether it is level with the adjacent pavers. If it is protruding upwards, use a rubber mallet to tamp it gently until it fits in place. If you notice that the new paver is below the level of the adjacent pavers, you will have to remove it so you can add more sand or mortar in the gap.
Step 6: Finishing Up
Once you are satisfied that the new pavers are placed neatly and level, fill the edges or joints around them with mortar. If the layer you used is sand, sprinkle some sand onto the paver and make sure it fills the gaps. Remove any excess when done.
