How to replace a broken paver comes down to three ideas: get the damaged unit out without cracking its neighbors, rebuild the bedding sand underneath, and set the new paver a hair proud so you can tap it flush. Because interlocking pavers sit on loose sand, you can swap one without touching the rest of the patio. A pry bar, a rubber mallet, a bag of bedding sand and a bit of patience are the whole kit.
Paver repair is one of the few home jobs that gets easier because the original installer did it properly. (If the pavers fought you on the way out, a lot of the credit goes to whoever filled those joints.)
Check whether it is one bad paver or a warning
A broken paver is the visible end of a problem that may be below it. Decide before you lift anything.
- A small chip on a corner or edge. Cosmetic. Many guides suggest filling the joints with polymeric sand and living with it, and replacing only if the chip is sharp or growing.
- A through-crack across the paver. Replace it. A cracked unit can open, shift and trip someone.
- Several cracked pavers in one line. Look at the base. The same spot cracking repeatedly is a base, drainage or traffic problem and not a manufacturing flaw.
- A cracked paver that also rocks or sits low. The bedding has failed or there is a void. See how to fix sunken pavers.
Outback Landscape's repair guide makes the same point: repeated trouble can point to a thin sand base, poor compaction, weak edging or drainage around the patio.
What you need before you start
Everything on this list is cheap, and most of it is already in the garage.
- Flat pry bar or flat screwdriver, plus a hammer and a masonry chisel
- A drill with a 3/8 inch masonry bit, for stubborn pavers
- Trowel or small shovel, and a small hand tamper
- A spare paver, or a replacement from the same product line
- Bedding sand (concrete sand, ASTM C33) and joint sand, or polymeric sand
- Rubber mallet, level or straightedge, and a broom
- Safety glasses and gloves
If the replacement needs to be cut, you also need a wet saw or masonry saw and a respirator. We will get to that.
How to replace a broken paver, step by step
- Mark the damaged paver. Chalk the outline if you are removing more than one.
- Free the joints. Scrape out the joint sand around the paver with a screwdriver or utility knife until you have space for a pry bar. If the joints are hardened polymeric sand, our guide to how to remove pavers covers breaking it up.
- Lift the broken paver. Work the pry bar under an edge and lift. If the sand is hard, Outback Landscape suggests wetting it to soften it. Be gentle so you do not chip the neighbors.
- Remove the old bedding. Scrape the old sand out with a trowel down to the compacted base and leave the base alone. Hunker's guide says the same: remove the sand, keep the gravel.
- Add fresh bedding sand. Spread about 1 inch of loose sand, screeded level. ICPI and CMHA both give 1 inch uncompacted as the standard, and CMHA's wording is blunt: do not disturb screeded sand.
- Test fit the new paver. Set it in the hole and check height against its neighbors with a level or straightedge. Adjust the sand until the paver sits slightly proud.
- Tap it flush. Use a rubber mallet, checking level as you go.
- Fill and settle the joints. Sweep sand into the gaps, tap the paver once more, and top up. For polymeric sand, mist gently to activate it.
Getting a stuck paver out
Some pavers do not lift. They are locked in by tight joints and compacted sand.
- Open a joint first. Scrape it out down to the sand bed, then use a narrow pry bar at the corner and work around the unit.
- Break it if you must. Hunker suggests drilling a few holes through the paver with a 3/8 inch masonry bit, then breaking it apart with a chisel. Aim the chisel inward, toward the broken paver and away from the ones you want to keep.
- Do not lever against a neighbor. Prying on the edge of a good paver chips it and creates a second repair.
Wear safety glasses. Concrete chips fly.
Reset the bedding to the right height
Height is where one-paver repairs go wrong. A new paver that sits low becomes a bowl for rain. One that sits proud becomes a toe-stubber.
- Sand thickness: about 1 inch of loose sand, uncompacted before the paver goes in.
- Settlement allowance: CMHA's guide specification lets pavers sit 1/8 to 1/4 inch above final grade before compaction, which is why tapping down is part of the job.
- Final height: ICPI Tech Spec 2 allows no more than 1/8 inch of lippage between pavers on a pedestrian route.
- Sand type: CMHA's guide spec calls for ASTM C33 concrete sand under the pavers. It says not to use stone dust, limestone screenings or mason sand, so do not use them for a patch.
If the base below feels soft or the hole is dished, do not bury it in sand. Add base material, compact it, and then start the sand layer. Two inches of sand in a low spot is a dip you have scheduled for next spring. Our paver patio repair guide covers bigger fixes.
Cutting a replacement to fit
Most single-paver swaps need a full paver. If the damaged one was a cut piece along an edge, you will need to cut a new one to match.
OSHA's rule for a handheld saw cutting masonry is water on the blade, every time, and indoors a respirator from the first cut (29 CFR 1926.1153, Table 1). Outdoors, no respirator is needed up to 4 hours a shift. Mark the paver, cut slowly, and test fit it dry. Our guide to how to cut pavers goes through the tools.
Joints, adhesive and the color mismatch
- Joints: plain joint sand works in most places. Polymeric sand locks the new paver in and matches an existing hardened joint. Our how to apply polymeric sand guide has the details.
- Adhesive: Hunker mentions construction adhesive on the sides as optional extra stability. I would skip it, because the next person (probably you) who needs to lift that paver will be cursing the glue.
- Color: a new paver will look different from a weathered one. Hunker suggests testing a few against the old ones after washing. Many patios blend in after a season, and a spare from the original order helps most.
Why the paver cracked
If you can find the cause, you can stop the next one. The usual suspects:
- A void under one spot, from washed-out sand, a downspout or ants, so the paver is bridging a gap.
- Wheel loads on a patio paver. CMHA says units with an aspect ratio of 4:1 or more, such as a 12 by 12 inch paver that is 2 3/8 inches thick, should stay off driveways.
- A thin or uncompacted base, which lets the whole area flex.
- Frozen, wet ground and a base that holds water.
Fix that first or the new paver joins the old one in the skip.
Fix what is under it, then drop the new one in
The paver is the easy part. Check why it cracked, rebuild the sand to a clean 1 inch, set the new unit a touch proud, tap it flush and fill the joints. One careful swap beats a patio of patched dips.
FAQ
Is it possible to swap a single paver without relaying the patio?
Yes. Pavers are laid on loose sand without mortar, so you can lift one out, rebuild the bedding and set a new one without touching the rest. Mortared pavers are harder.
How do you remove a broken paver that is stuck?
Scrape the joint sand out first, then work a narrow pry bar under the corner. If it will not lift, drill several holes through the paver with a 3/8 inch masonry bit and break it apart with a chisel, aiming inward.
How do you level a replacement paver with the rest?
Spread about 1 inch of loose bedding sand, set the paver a little above its neighbors, then tap it down with a rubber mallet while checking with a level or straightedge. CMHA's allowance is 1/8 to 1/4 inch above final grade before settling.
Do you need polymeric sand after replacing a paver?
Not necessarily. Plain joint sand works in many cases. Polymeric sand gives a firmer, more durable joint and matches existing polymeric joints, but needs dry joints and gentle misting.
Why do pavers keep cracking in the same place?
Usually something underneath: a void, a soft or thin base, poor drainage or loads the paver was not meant for. Fixing the cause matters more than swapping the unit again.
