Brick Paver Patio Repair: How to Level Sunken Bricks
If you have a brick paver patio, it is common for some of the bricks to not be completely flush. Luckily, leveling your patio isn’t hard to do, no matter what brick-paver patio design you have. The process involves figuring out which of the bricks are sunken through the use of a furring strip and/or level, removing the sunken brick(s), and adding sand to raise the brick(s).
This how-to article will discuss the necessary steps, along with the correct tools and materials, for repairing your brick paver patio.
Step 1 – Lay Out a Furring Strip
You will need to mark the bricks that do not sit flush in your brick patio. You can do this by using a furring strip.
A furring strip is a thin piece of wood that forms a frame or template used when building basement walls and decks made with concrete blocks or paver bricks. The furring strip allows you to maintain the pattern for the deck. You can purchase a furring strip at a home-improvement center, or you can create one yourself with vinyl or wood-veneer strips.
Place the furring strip across the length of the area and mark the bricks that appear below the line of the strip. You can also do this with a level, but using the furring strip will make the task of identifying sunken bricks go faster and easier.
Step 2 – Remove Marked Bricks
Once you have identified the bricks that are sunken and in need of leveling, use a trowel to carefully remove them from their spots. If the paver is damaged, you need to have replacement ones on hand to put in place of the damaged ones. Whether you've bought pre-cut pavers to the appropriate size or you've cut them yourself, make sure they're the same size as your damaged ones.
If you have a large number of them that are sunken, it is best to work on leveling the sunken bricks one at a time, especially if you are unable to complete the project in a single afternoon.
Step 3 – Add Sand to Level Bricks
After removing the sunken brick, place an appropriate amount of multipurpose sand into the resulting spot to level it. This process involves trial and error because you will not know how much sand to place into the hole until you place the paver inside and check the level. This is also why you should work one paver at a time.
Step 4 – Level the Sand and Reposition Bricks
When adding the sand, use the back of the trowel or the level to smooth the sand out before placing the brick inside. You want as smooth a surface as possible when placing the brick paver in to create the even level you’re looking for. Repeat this process for each sunken paver.
