# Can pavers go over an existing concrete pool deck?
The concrete deck is stained, crazed and patched, and breaking it out sounds like weeks of noise and a mountain of rubble. Laying pavers straight over it sounds like the obvious shortcut, and sometimes it is. The concrete paver industry's own guidance allows it. What the shortcut does not advertise is that the deck comes up in height, that the old slab's slope and cracks come along with it, and that the water that soaks through the new surface needs somewhere to go.

A paver overlay is a new paver surface laid over an existing concrete slab instead of on a new compacted base. The pavers sit either on a thin layer of bedding sand with sand-filled joints, or bonded to the slab with a mortar bed. The old slab stays in place and becomes the base.
The short version
I. Existing concrete can be overlaid with concrete pavers, and pool decks are among the uses the industry's application guide lists (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1).
II. Thin paving units of 1 1/4 to 1 3/4 inches are used for overlays, on bedding sand screeded 1 to 1 1/2 inches thick (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1). On our arithmetic the deck rises roughly 2 1/4 to 3 1/4 inches.
III. Water that soaks into the bedding sand has to drain out, through holes at the low points of the slab or to drains, covered with fabric so the sand stays put (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1).
IV. Bedding sand is never used to fill dips, so the old slab's slope and low spots come through to the new surface (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1).
V. At the required exit door, an outside landing may sit no more than 7 3/4 inches below the threshold and slope no more than 2 percent (Florida Building Code, Residential, 2023) [3](#ref-3). The code sets no minimum gap, so check the doors before ordering pavers.
VI. A slab that is sinking, breaking up or sloped toward the pool is a poor base. Overlaying it hides the problem without fixing it.

I.

## Can pavers go over an existing concrete pool deck?
Yes, in the right conditions. The concrete paver industry's application guide says new or existing concrete pavements can be overlaid or inlaid with pavers, and it lists pool decks among the uses it covers (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1). The conditions are about drainage, cracks and joints in the slab, the thickness of the units and the height the deck gains.
The application guide describes two versions. An overlay sits on top of the existing slab. An inlay grinds part of the old surface out and sets the bedding sand and pavers into the milled area, which keeps the finished height down (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1). On a pool deck the overlay is far more common, because grinding a whole deck down is its own project.
In both cases the old concrete becomes the base, and that is the whole bargain. A sound, well-sloped slab is an excellent base, and laying over it avoids demolition, hauling and the time a new base takes to build. A cracked, sinking or badly pitched slab hands every one of those faults to the new surface, which is why the [post on resurfacing a cracked deck](https://www.splashpoolsllc.com/blog/can-a-cracked-pool-deck-be-resurfaced-naples/) starts with the slab rather than the finish.
The guidance quoted here is written for concrete pavers. Natural stone such as travertine is a different product with its own installation guidance, and the [travertine pool deck page](https://www.splashpoolsllc.com/travertine-pool-deck-naples/) covers the stone itself. Whatever the material, the questions below about height, slope, water and cracks apply the same way.
II.

## How much higher will the deck sit with pavers on top?
Higher than most owners expect. Thin paving units made for overlays are 1 1/4 to 1 3/4 inches thick, and bedding sand is screeded 1 to 1 1/2 inches thick before compaction (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1). On our arithmetic, a sand-set overlay raises the surface roughly 2 1/4 to 3 1/4 inches. A bonded overlay adds less, the paver plus its mortar bed.
Those thin units are a specific product, and the guide limits them to pedestrian use: they are sand set on or adhered to a concrete base for walkways and decks and are not recommended for any vehicle area (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1). A pool deck is exactly the pedestrian case they were made for. Standard full-thickness pavers laid over a slab would raise the surface further still.
Inches matter on a pool deck because almost everything the deck touches was built to the old surface height: the sliding doors, the coping around the pool, the screen enclosure door and its kick plate, deck drains, hose bibs, the base of a spa, and the edge where the deck meets the lawn or a planting bed. Each of those has to be looked at before the height is settled.
The way to remove the guesswork is to measure, not estimate. Ask for the finished surface height at each door, at the coping and at each drain, written into the quote. A contractor who has done overlays will expect the question, and the answer decides whether an overlay works at all on that deck or whether an inlay, a thinner bonded install or a tear-out is the better route.
III.

## What happens at the sliding doors, the coping and the screen?
Each one loses some of its clearance. At the required exit door, Florida's residential code allows an outside landing no more than 7 3/4 inches below the threshold and limits a landing's slope to 2 percent (Florida Building Code, Residential, 2023) [3](#ref-3). It sets no minimum gap, so a raised deck can be legal and still let wind-driven rain reach a door track.
The code rules exist for safe exits, not for keeping water out. They say a landing must be at least 36 inches deep in the direction of travel and slope no more than a quarter inch per foot, and that landings at the required egress door sit no more than 1 1/2 inches below the threshold, with an exception that lets the outside landing sit up to 7 3/4 inches below it (Florida Building Code, Residential, 2023) [3](#ref-3). Raising the outside surface toward the threshold does not break those rules. What it removes is the step that stops a summer storm running toward the door.
The coping is the other critical edge. Where the coping sits at or near the deck surface today, raising the deck 2 or 3 inches can leave the coping below it, so rain runs off the deck and into the pool over it. The fix is usually new coping set at the new height, which the [coping replacement page](https://www.splashpoolsllc.com/pool-coping-replacement-naples/) explains.
The screen enclosure is easy to forget. Its door has a fixed swing clearance and its kick plates and footer sit at the old deck height. A raised deck can stop the screen door clearing, and it can put the base of the cage below the new surface where water collects against it. None of this is a reason not to overlay. It is a list of places to measure first.
IV.

## Will the new paver surface follow the old slab's slope?
Yes, and its low spots too. The application guide says bedding sand is screeded to a consistent thickness and must not be used to fill depressions, which eventually show through in the finished surface (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1). If the slab falls toward the pool or holds water today, the pavers on it will do the same unless the slab is corrected first.
This is the part of the shortcut that disappoints people. An overlay changes what the deck looks like, but the shape of the deck is still the shape of the slab. The guide specification is blunt that the installer cannot correct deficiencies in the base surface with additional bedding sand (Concrete Masonry and Hardscapes Association, 2013) [2](#ref-2), and on an overlay the base surface is the old concrete.
Florida's code gives a benchmark for how much fall a deck needs: public pool wet decks are sloped 2 to 4 percent away from the pool or to deck drains, with 1 percent allowed for paver-type decks (Florida Building Code, Building, 2023) [4](#ref-4). A private deck is not held to that rule, but a slab that measures well under it in places will hold water under any surface laid on top.
If the deck holds water now, read the [guide to pool deck drainage](https://www.splashpoolsllc.com/blog/pool-deck-drainage-standing-water-naples/) before choosing pavers. Correcting the fall, by grinding high spots, patching and building up low areas properly, or adding drains, is far easier before the pavers go down than after.
V.

## Where does the water under the pavers go?
Out through the slab or to a drain, if the installer plans for it. Rain soaks through sand-filled joints into the bedding layer, and on a solid slab it has nowhere to go. The application guide calls for draining that moisture with vertical holes at the slab's lowest points or with holes leading to drains, covered with fabric so the sand stays in place (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1).
On an ordinary paver deck the water passes down through the bedding sand and into a porous base below. A concrete slab stops it, so without a way out the bedding layer simply stays wet. That is why the guide says consideration should be given to draining excess moisture from the bedding sand whenever pavers go over existing concrete (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1).
Deck drains need the same attention. The guide says drains in a paver surface must have holes or slots at the level of the bedding sand so the moisture in it can escape, covered with fabric to stop sand washing in (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1). An existing slot drain set flush with the old concrete will usually need to be raised or replaced so the new surface still steps down into it.
Ground conditions matter too. Where drain holes would empty into soil that does not drain or that swells, the guide says they will need to be piped to a suitable outlet (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1). Ask the installer where every drain hole will lead, and expect the answer to be specific.
VI.

## What has to be done about the cracks in the old slab?
They have to be dealt with before anything goes on top. The application guide says cracks 3/8 inch or wider should be patched first, and that fabric may need to be laid over the slab's joints and cracks, typically in strips about 12 inches wide (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1). Otherwise bedding sand drains down into them and the pavers above settle.
Sand-set pavers do not care much about a hairline crack under them, as long as the sand cannot escape into it. That is what the fabric strips do. Over the slab's control joints and cracks, the fabric keeps the bedding layer in place while the slab beneath moves slightly with heat and moisture (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1).
Wide or active cracks are a different matter. A crack that is opening, a section that has dropped or a slab that rocks underfoot is telling you the ground or the concrete is moving, and pavers will follow it down. Those are slab repairs first, and sometimes a reason to remove the slab instead, which the [pool deck repair page](https://www.splashpoolsllc.com/pool-deck-repair-naples/) covers.
Cracks near the pool deserve one more check. A crack line that runs toward the pool, or a wet patch that never dries beside it, can be a sign of water coming from the pool rather than the sky, and the [guide to telling a leak from evaporation](https://www.splashpoolsllc.com/blog/pool-losing-water-leak-or-evaporation-naples/) is worth a read before the slab disappears under a new surface.
VII.

## Is sand-set or mortar-bonded better over a pool deck slab?
Each has a place. For bonding pavers to existing concrete in pedestrian areas, the application guide recommends a latex-modified thinset or thickset mortar, and it limits mortared pavers to pedestrian areas without freeze and thaw (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1). Naples qualifies. Sand-set units add more height but can be lifted and relaid when something under them needs work.
Bonded pavers are attached to the slab, so they add the least height and do not shift on a wet bedding layer. The trade-off is that they move with the concrete. A crack that opens in the slab can show up through a bonded surface, and lifting a bonded paver to reach something underneath usually means breaking it out.
Sand-set pavers float on their bedding layer with sand in the joints. The guide points out that interlocking pavers can be reinstated after repairs (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1), which on a pool deck means a plumbing repair or a drain replacement can be done by lifting a section and relaying it. The cost of that flexibility is height and the drainage work described above.
Either way, the edges have to be held. The guide calls edge restraints essential to how interlocking pavers perform, because the restraint is what keeps the units and sand locked together (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1). On an overlay that usually means a restraint fixed along every open edge of the slab, at the lawn, the beds and the screen footer.
VIII.

## When is tearing out the concrete the better choice?
When the slab is the problem rather than the surface. A deck that is sinking, broken up, pitched toward the pool or already too close to the door thresholds will hand those faults to any overlay. Removing it costs more up front, but it lets the new deck be built at the right height, with the right fall and a base that drains on its own.
The height question alone can decide it. If the doors, coping and screen leave no room for 2 or 3 more inches, an overlay means replacing the coping, adjusting the screen and living with a smaller step at the doors. At that point, removing the slab and building a new paver base at the original height can be the simpler job.
The same goes for a slab with no usable fall. Building up low areas under an overlay is possible, but it is real work, and on a deck that slopes the wrong way it can be more work than starting again. The [pool decks and pavers page](https://www.splashpoolsllc.com/pool-decks-pavers-naples/) explains how a new base is built, including the base thickness the guidance calls for under patios.
There is also the question of how much paved area the property carries. Extending the deck while the work is under way changes that picture, and the [post on paver decks and impervious area in Collier County](https://www.splashpoolsllc.com/blog/paver-pool-deck-impervious-area-collier-county/) explains why it matters there.

## What should a quote for pavers over concrete spell out?
The finished heights, the drainage and the slab work, in writing. A good quote says how high the new surface will sit at each door, at the coping and at each drain, whether the units are sand-set or bonded, where the drain holes go, how cracks and joints are treated, what edge restraint is used, and what happens to the coping and the existing drains.
Height first. Written heights at the doors and coping turn the most common overlay surprise into a number you can check before work starts. If the quote does not mention the coping at all on a deck that is coming up 2 or 3 inches, ask what the plan is for it.
Then drainage and cracks. The quote should name the number and location of drain holes or the drains they lead to, the fabric over joints and cracks, and which cracks are being patched before the overlay (Concrete Masonry and Hardscapes Association, 2022) [1](#ref-1). It should also say how existing deck drains will sit relative to the new surface, which the guide specification puts at 1/8 to 3/8 inch below the pavers (Concrete Masonry and Hardscapes Association, 2013) [2](#ref-2).
Finally, compare like with like. A sand-set overlay, a bonded overlay and a tear-out with a new base are three different jobs, and the [guide to choosing a deck resurfacing contractor](https://www.splashpoolsllc.com/blog/choose-pool-deck-resurfacing-contractor-naples/) explains how to tell which one each quote actually describes before comparing them.
