It is necessary to replace driveway pavers when they becomedamaged as the result of everyday wear and tear. This is true of both concrete driveway pavers and brick driveway pavers. Loose pavers can cause safety problems. People can trip over them and they are also an issue for vehicle tires that are continuously being driven over them. Because of potential problems, it is important to remove problem pavers as soon as you notice something wrong. Both types of pavers are replaced in much the same way.
Step One: Preparations and Safety
Gather tools in one place and make sure always wear safety gloves and glasses. Paver removal, cutting and installation can all be hazardous procedures and you need to wear sufficient protection at all times.
Step Two: Remove Old Pavers
Remove cracked and broken pavers. Some damaged pavers may lift out easily but different measures need to be taken with pavers that are set into the ground. Lift them by tapping into the side of each individual paver with a mallet and bolster. Once the pavers have been removed, clear the area of broken paver and garden debris to leave a flat, even working surface.
Step Three: Replacing the Sand
Put a layer of sand into the areas where the pavers have been removed. Push the sand into all corners of the remaining pavers, using a wooden mallet to make sure that the sand is distributed evenly. Compact the sand in those areas well and pat the exposed sand flat. You can lightly sprinkle powdered concrete mix on top of the sand.
Step Four: Leveling
Before continuing, use a spirit level to check that the sand base is completely leveled. If it is not, level it with the wooden float and check again.
Step Five: Lay the New Pavers
New pavers are ready to be installed. Use a screwdriver to make sure that the gaps around each paver are even. Use the screwdriver to force pavers over slightly by using existing pavers as a wedge.
New pavers should be at the same level as the old pavers. If this is not the case, sand can be added or removed. Try fitting the pavers again once you have made the adjustments. Tap the pavers into place using the rubber mallet. Make sure that they settle into the area evenly.
Step Six: Pouring the Sand
Pour a 50/50 sand and concrete mixture over the newly installed pavers. Be sure that each gap is completely filled in. Wet the area with a light spray and allow the mixture to dry. Cover the area with additional sand and concrete mix and let the mixture dry.
Step Seven: Finishing Up
Once the mix is dry, sweep the area with a stiff broom to remove any debris or surplus mixture. Clean and put away all materials and save the remainder of the sand for a future project
