Pavers Over Existing Concrete Patio — Overlay or Tear Out
Your concrete patio is plain, stained or a little rough but still flat, and you want it to look like pavers without paying to break it out.
JMB Builders lays pavers over an existing concrete patio in Minnesota when the slab is sound: no heaving, no wide cracks, and enough room under the door for the added height. We clean the slab, set a drainage path, build an edge restraint on the slab edge, and lay thin overlay pavers on a sand or mortar bed. Cracked or heaved slabs get torn out. Priced per project after a look.

A concrete slab can be a good base for pavers, or a bad one. If the slab is flat and has not moved, it is already a solid, compacted surface, and an overlay saves the tear-out and the haul. If it has heaved, sunk at one corner or cracked into pieces that move, the pavers will follow every crack and every heave, and the slab has to come out.
The second check is height. Overlay pavers plus their bed add height to the patio. At a patio door or a house step, that can close up the step down or put the patio above the door threshold, which sends water toward the house. We measure the step at the door before quoting. If there is not room, the answer is a tear-out.
When the slab passes both checks, the build is: clean the slab, make sure water still runs off it away from the house, fix an edge course or restraint around the slab edge so the overlay cannot spread, and lay thin pavers on a thin sand bed with drainage or a mortar bed, depending on the paver and where water goes. Joints get polymeric sand or mortar to match.
What you supply

What JMB supplies
- A look at the slab: level, cracks, heave and the step height at each door
- Slab cleaned; small cracks and low spots evened out
- A drainage path so water still runs off the patio, away from the house
- Edge course or restraint set on or at the slab edge
- Thin overlay pavers on a sand bed or mortar bed, cut to fit
- Polymeric sand or mortar in the joints
- A tear-out and new base instead, if the slab fails the check
- Photos of the finished patio in your job folder
How it is priced: per project
Quoted in writing from your photos within one business day. What moves the number:
- Patio size in square feet
- Slab condition: sound as is, or needs cracks and low spots fixed
- Sand-set vs. mortar-set overlay
- Paver choice and pattern; herringbone and borders mean more cuts
- How the edge restraint is built on the slab edge
- Steps or a stoop included in the overlay
- Tear-out and new base if the slab cannot take an overlay
Send photos of the whole slab, any cracks, and a tape measure at the door showing the step down to the patio. That tells us whether an overlay is even possible.
How long it takes
A typical patio overlay: two to three days. A tear-out and full new base instead: three to five days.

Situations and options
Sand-set overlay
Thin pavers on a thin sand bed over the slab, with a drainage path so water under the pavers can get out. Faster, and pavers can be lifted later.
Mortar-set overlay
Pavers or stone set in mortar bonded to the slab, with mortar joints. Suits a front stoop or steps where the pavers must not shift.
Overlay plus an extension
The slab gets an overlay and the patio grows past its old edge on a new compacted base, with the two surfaces finished at the same height.
Tear out and rebuild
When the slab is heaved or broken, it is broken out and hauled, and the patio is rebuilt on a compacted base like any new paver patio.
Pavers Over Existing Concrete Patio — Overlay or Tear Out: questions, answered
Can you put pavers over a concrete patio?
Yes, if the slab is flat, not heaving and not badly cracked, and there is room under the door for the added height. A sound slab makes a good base and saves the tear-out. A cracked or heaved slab passes its movement to the pavers, so it has to come out first.
How much height do pavers add over concrete?
It depends on the paver thickness and whether it is sand-set or mortar-set; thin overlay pavers are made to keep it low. The added height matters most at a patio door or house step. We measure the step before quoting so the patio stays below the threshold.
Will pavers over concrete heave in a Minnesota winter?
Only if the slab under them heaves. A slab that has sat flat through many winters is on stable ground and usually stays that way. Water trapped between the pavers and the slab can freeze, so the overlay is built with a drainage path off the slab.
How do you keep pavers from sliding off a concrete slab?
With an edge restraint. The outside course is set in mortar on the slab edge, or a restraint is fixed to the slab, so the field pavers are locked in. Without it the edge pavers creep off the slab over time.
Is it cheaper to overlay concrete than tear it out?
Usually, because there is no breaking, hauling or new base. It only saves money if the slab is sound; an overlay on a moving slab fails and then gets torn out anyway. We tell you which one the slab needs after we look at it.
Can you put pavers over concrete steps?
Yes, when the steps are solid. The treads and risers get mortar-set pavers or a cap, and the bottom step height is checked so every step stays even. Rules for step heights at a house entry apply, so we measure before quoting.
