Thin pavers are concrete, clay brick or natural stone pavers about 1 to 1 3/8 inches thick, instead of the usual 2 3/8 inches, and they are made for one job: covering a surface that is already solid, usually a sound concrete patio, porch, walk or pool deck. Set on mortar over the slab, they add about 1 1/2 inches of height instead of 3 1/2 and weigh about 40% of a standard paver per square foot. They are not a cheaper way to build a patio on gravel, and they are not for driveways.
I went through the spec sheets from Wausau Tile, Belgard and Pine Hall Brick to see where the manufacturers draw the line. They all draw it in the same place, just in different fonts. We have a separate page on pavers vs tile outdoor if you need the specifics.
What counts as a thin paver
"Thin" is a marketing word, not a standard, so it helps to know the reference point. The concrete paver standard, ASTM C936, defines a paver as a unit at least 2 3/8 inches (60 mm) thick, according to CMHA's Tech Spec 10. Anything thinner is sold as an overlay paver, remodeling paver, slim paver, paver tile or thin brick, and it is tested against its own product sheet rather than that definition.
In practice, thin patio pavers fall into four families:
- Thin concrete pavers. Belgard's paver overlay page describes 30 mm (about 1 1/4 inch) concrete pavers for refreshing tired concrete, and 50 mm slabs for larger formats. Wausau's Thin Series is 1 inch.
- Thin clay brick pavers. Pine Hall Brick sells 1 3/8-inch clay pavers for mortared work over concrete, plus 1/2-inch "PaverTiles" that install like ceramic tile. "Brickface" or thin brick flooring sits in the same family.
- Thin stone pavers. Travertine, bluestone, sandstone and limestone sawn to about 1 inch, sold specifically for mortar-set overlays.
- Porcelain. Outdoor porcelain is usually 2 cm (about 3/4 inch).
A thin paver looks the same as a standard one from above. The difference is entirely in the side view, which is the view nobody photographs.
Thin concrete, brick and stone pavers compared
| Type | Typical thickness | Usual setting method | Strong points | Watch for |
|---|---|---|---|---|
| Thin concrete | 1 to 1 1/4 in (25 to 30 mm) | Mortar, dry mudset, or thin sand bed on a slab | Cheapest per sq ft, matches full-thickness lines from the same brand | Only the brand's own sheet vouches for its strength |
| Thin clay brick | 1/2 to 1 3/8 in | Mortar or thinset on a slab | Real fired clay color that doesn't fade | Buy a product rated for exterior freezing if you get winters |
| Thin natural stone | about 1 in | Mortar-set on a slab | Natural look at far less weight than 2-inch flagstone | Softer stones need sealing and careful joints |
| Porcelain | about 3/4 in (2 cm) | Mortar, pedestals, or sand over a stiff base | Near-zero water absorption, stain resistant | Hard to cut cleanly, slick if the finish is polished |
The Wausau Thin Series sheet is a good example of what a solid thin concrete product should publish: compressive strength above 9,500 psi, water absorption under 5%, and freeze-thaw resistance of under 1% weight loss. If a thin paver you are looking at lists no test results at all, treat that silence as the result. Worth a read next: winterizing pavers.
Where thin patio pavers earn their place
Thin pavers solve a height problem and, sometimes, a weight problem. Nothing else. They are the right call when:
- A door sits close to the slab. A standard sand-set overlay adds about 3 3/8 inches (a 2 3/8-inch paver on 1 inch of sand). A thin paver on a mortar bed adds about 1 1/2. At a sliding door with 2 inches of clearance, that is the difference between a project and a leak.
- A porch or stoop already has steps. Raising the landing changes the top riser. Keeping the overlay thin keeps the step heights close to even.
- A pool deck meets fixed coping. You can't lift the coping, so the new surface has to stay low.
- Weight matters. Balconies and roof decks can't take a full paver field. That is its own subject, with load limits and pedestals, and it lives in our guide to lightweight pavers.
If none of those apply, especially on bare ground, there is no reason to buy a thinner paver. You'd be buying less paver to carry the same load.
Why a 1-inch paver needs a slab under it
This is the opinion I hold most firmly on this topic: thin pavers are a resurfacing product, not a patio-building product. If there is no sound slab under them, buy full-thickness pavers.
The mechanism is simple. A 2 3/8-inch paver on sand is both the surface and a stiff block that spreads your weight into the base. When the base settles slightly in one spot, a thick paver bridges it and the joint sand keeps it locked to its neighbors. A 1-inch paver has less than half the depth to resist bending and much less mass to stay put. Over a soft spot it tilts or cracks across the middle. (A thin paver on gravel is a cracker on a mattress.)
On a concrete slab, that weakness stops mattering. The slab carries the load, and the paver only has to be a surface. That is why Wausau lists its Thin Series for thin set, mortar set and a paver grid system only, and why Belgard pitches its thin units as an overlay for existing concrete.
The slab has to deserve it, though. Heaving sections, cracks with one side higher than the other, or a slab that holds water will pass all of that straight through to the new surface. Our guide to pavers over concrete walks through which slabs qualify, drain holes and how to hold the edges.
Height, weight and what a thinner unit saves
Here is the arithmetic that usually decides the order:
| Build over a slab | Paver | Bed | Height added |
|---|---|---|---|
| Standard paver, sand-set | 2 3/8 in | 1 in sand | about 3 3/8 in |
| Thin paver, sand-set | 1 1/4 in | 1 in sand | about 2 1/4 in |
| Thin paver, mortar-set | 1 in | 3/8 to 1/2 in mortar | about 1 1/2 in |
Weight follows thickness almost exactly. Wausau puts its 1-inch pavers at 13 lb per square foot. Scale that same concrete to 2 3/8 inches and you're near 31 lb per square foot. On a 200 sq ft porch, that's roughly 2,600 lb of thin pavers against about 6,200 lb of standard ones: fewer pallets, a lighter load on a suspended porch, and a much kinder afternoon for whoever carries them.
Setting methods for thin pavers
Three methods show up on the product sheets:
- Mortar set. Latex-modified mortar bonded to a clean slab, with mortar or a rigid-rated compound in the joints. Most common for thin stone and brick.
- Dry mudset. Belgard describes a dry mix that spreads like sand and is activated by spraying water once the pavers are down, bonding them to the slab.
- Thin sand bed. Some thin concrete pavers can go on sand over the slab, with drain holes and a restraint fastened to the concrete. Brands disagree here, so follow your paver's sheet.
Many thin units should not see a plate compactor at all; they are seated with a rubber mallet. Crack one with a rented plate and the rental just got more expensive by one paver and one bad mood.
Limits to check before you order
- No driveways, unless the maker says so. Thin overlay units are sold for foot traffic. Belgard does say its 20 mm porcelain can take a driveway on a concrete base, which tells you the concrete base is doing the work.
- Freezing climates. Ask for the freeze-thaw result on the sheet. For clay, look for an exterior freeze rating; for stone, ask about absorption.
- Cuts and slivers. Edge cuts on a thin paver snap more easily than on a thick one. Lay out the pattern so edge pieces stay at least a third of a paver.
- Edges. A thin field on a slab still needs a finished edge: a bullnose, a border set in mortar, or a restraint fastened to the concrete. An exposed 1-inch edge chips.
What thin pavers cost
I could not find a national price survey for thin pavers specifically, so I'll give you the one breakdown I found with its working shown. Chief Bricks' thin stone paver guide puts the stone itself at $4 to $15 per square foot, labor at $10 to $20, and mortar, sand and sealer at $2 to $4, for a total of about $16 to $39 per square foot. It compares that with $25 to $50 or more for jobs that include tearing out the old slab.
The real saving is in what you skip: demolition, hauling and a new base. If the slab is sound, that's the whole argument for a thin overlay. If it isn't, the argument evaporates.
Keep a sound slab, and a thin paver makes sense
Thin pavers change what a solid surface looks like without changing much else: an inch and a half of height, less than half the weight, no demolition. The slab does the structural work. On concrete that doesn't move, they look like any other paver for decades. On gravel, you've bought the one paver designed to break. Measure under every door, check the slab for rocking sections, and ask for the test sheet. Still undecided on thickness? Our paver thickness guide sets out every size and where it belongs.
FAQ
How thick are thin pavers?
Most thin pavers are 1 to 1 3/8 inches thick. Thin concrete overlay pavers usually run 1 to 1 1/4 inches (25 to 30 mm), thin clay pavers are often 1 3/8 inches, thin stone is sawn to about 1 inch, and outdoor porcelain is about 3/4 inch (2 cm). Standard pavers are 2 3/8 inches.
Can you put thin pavers on gravel or dirt?
No. A thin paver can't bridge small dips in a base and weighs too little to stay locked in place, so on gravel or soil it rocks, tilts and cracks. Use full-thickness pavers for a sand-set patio on a gravel base, and save thin pavers for sound concrete.
Are thin pavers strong enough to drive on?
Not as a rule. Thin concrete overlay pavers are sold for foot traffic. A few products are rated for vehicles when bonded to a concrete slab, but in that case the slab is carrying the car. Use 2 3/8-inch or 3 1/8-inch pavers on a proper base for a driveway.
Are thin pavers cheaper than regular pavers?
Per square foot of material, usually a little. The bigger saving comes from skipping demolition and base work when you already have a sound slab. Mortar setting costs more than sand setting, so the installed price isn't always lower.
