How to Repair Driveway Paving Stones How to Repair Driveway Paving Stones
Driveway paving stones lend a great rustic appeal to your driveway that asphalt and concrete simply cannot provide. Since driveway paving stones are a natural material they are subject to damage by the elements. They can sink and rise, become stained and even break due to expansion and contraction or from bearing too much weight. Thankfully driveway paving stones are just as easy to replace as they are to install. These steps will help you complete a seamless replacement.
Step 1 – Loosen the Driveway Paving Stones
Mortar and concrete is never used to install driveway paving stones because those materials make it impossible to make repairs. This is why compacted sand is used in place of those materials. Once the sand dries out it forms a bond nearly as hard as concrete without being infinite in its lifespan. In order to loosen the stones all you need is a garden hose. Turn the water on and saturate the joints of the stone or stones you need to remove. The sand needs to be soft so 2 minutes should be a long enough time to properly saturate the joints.
Step 2 – Remove the Stone
With the sand properly saturated you can now remove the actual stone. This can take some work depending on the type of driveway paving stones you used. There are many kinds from brick to 4-inch thick square blocks and anything in between. The general idea is that they have to be pried up and so they make a special removal tool for this but you can use a pair of ordinary forks. Slide the handle of the fork or tool along the edges of the driveway paving stones to be removed and scrape out as much sand as possible from around the edges. Once the sand is properly removed you can then remove the stone. Use the tool as leverage or insert a fork at opposite sides and grip the stone and lift up.
Step 3 – Replace the Stone
Simply place the new driveway paving stones in the open areas where the old stones were. Once they are inside the space you will need to seat them. Use a rubber mallet and gently tap them all over the surface until they are even with the other driveway paving stones. You now need to make sure they will not move so pour sand over the stone you replaced and then smooth it out with a push broom. Make sure the sand fills the gaps and then water the area down again with the garden hose as you did in Step 1. This will help to settle the sand in the gaps and when it dries will create that strong bond. You may need to add more sand to completely fill the gaps.
