Planning to resurface pool deck with pavers? You can do it without tearing out the concrete, if the slab is sound and you solve one problem before you buy anything: height. Thin overlay pavers laid over the old deck raise it by their thickness plus the setting bed. That new surface has to finish at or just below the pool coping and still fall away from the water. Measure the coping, the deck drains, the skimmer lids and every door threshold first. The paver you choose comes second, and it is the easy decision.
A pool deck overlay is really a pavers over concrete job with a swimming pool parked in the middle of it. That guide covers slab inspection, drain holes and the three setting methods in full. This one covers what the pool changes.
Check the slab before you resurface the pool deck with pavers
Treat the old deck as a base. If it's moving, the pavers will show every move.
- Hairline cracks and surface wear. Fine. Overlaying cosmetic damage is the whole point.
- Cracks with one side higher than the other. The slab is moving, often from settled fill around the pool shell. An overlay will crack or rock along the same line.
- Hollow-sounding or rocking sections. Voids under the slab. Break these out.
- Standing water after rain. The pitch is wrong, and an overlay only hides it for a while.
Most in-ground pools sit in over-excavated, backfilled ground, and backfill settles. A deck that has sunk toward the pool is a candidate for removal and a proper compacted base, not an overlay.
Coping height decides whether an overlay works
This is my one strong opinion here. The coping, not the paver, decides whether you can resurface a pool deck with pavers. Measure it before you look at a single sample.
On most concrete pool decks the deck meets the back of the coping at about the same height. Add an inch or two of pavers and bedding, and the deck now stands above the coping. That leaves a lip at the pool edge that catches toes, and splash-out drains back into the pool with whatever it picked up on the deck. The deck has to finish level with the coping or slightly below it, and slope away from the pool.
You have three ways to get there:
- Use the thinnest build possible. Porcelain pavers at 2 cm (about 3/4 inch) set in a thin adhesive or mortar bed add the least height. On some decks that's enough.
- Replace the coping at the new height. Remove the old coping and set new paver or stone coping on the bond beam, raised to match the overlay. This is the cleanest result. Removing coping can disturb the tile line, though, so it is often a job for a pool contractor.
- Remove the deck. If neither works, take the slab out and build a full-depth paver deck at the right height.
Where people go wrong is ordering pavers first and finding the problem when the first row meets the coping.
New coping: what the manufacturers say
If the coping is being replaced, it goes on in mortar, never on sand. I compared two manufacturer coping guides, and they don't fully agree.
- Belgard's contractor's notes on paver pool coping call for a consistent 1-inch overhang. They say to set the coping level in mortar and not pitch it, since the deck itself will be pitched. They also call for foam expansion material between the coping and the deck pavers.
- Unilock's pool coping installation guide calls for a reinforced concrete collar at least 6 x 6 x 6 inches. The coping is set with a modified mortar, has about a 2-inch overhang and slopes at 2% away from the pool.
The difference is in the product details, so follow the guide for the coping you actually buy. Both agree on the part that matters most. The coping is bonded to the pool structure, and the joint between it and the deck stays flexible.
Leave the joint at the coping flexible
The pool shell and the deck move differently with temperature and ground moisture. The joint between them has to move too.
- Never mortar or glue the deck pavers to the back of the coping.
- Fill that joint with a foam backer rod and a flexible, self-leveling sealant.
- Run the deck's own expansion joints through the overlay where they exist in the slab below. A glued overlay spanning a slab joint will crack along it.
A rigid joint here is the usual source of a cracked coping line a winter or two later.
Deck drains, skimmer lids and doors
The overlay raises everything that sits in the deck surface. Walk the deck with a tape measure and list each item:
- Deck drains. Strip or channel drains buried under the overlay stop working. Plan to raise them with extensions, replace them with new channel drains at the new height, or re-pitch the deck to a new drain line.
- Skimmer lids. Most need an extension collar so the lid sits flush with the new surface.
- Ladder and rail anchors. Their sockets have to come up with the deck, or the rails end up short.
- Door thresholds and gates. Keep the finished surface below the door sill, and check that gates still clear the new deck and still latch.
Drainage is the part that gets skipped. On a normal paver deck, water goes down through the joints into the gravel. On an overlay, it hits the old slab. Sand-set overlays need drain holes at the low points, and glued or mortared ones must shed water across the surface to a drain. The finished deck should fall away from the pool, and the IRC asks for hard surfaces within 10 feet of a house to fall at least 2% away from it (section R401.3). The pool deck width guide covers this in more depth.
Choosing thin pavers for a pool deck overlay
Pool deck overlay pavers are usually thin concrete pavers, porcelain or travertine. Things to check:
- Thickness against your height budget. Thin concrete overlay pavers are commonly around 1 1/4 inches; 2 cm porcelain is about 3/4 inch. Check the exact product.
- Texture. Wet, bare feet need a textured, non-slip face.
- Color and heat. Lighter colors stay cooler in the sun.
- Salt and chlorine. Splash-out from a saltwater pool is hard on some surfaces. Look for a manufacturer statement on salt resistance, and rinse the deck regularly.
Material choice, traction and heat are covered in detail in our guide to pool deck pavers.
What a paver overlay costs against the alternatives
Dustless Blasting's pool deck resurfacing guide puts pavers at about $2 to $30 or more per square foot for materials, plus around $5 to $10 for labor. That comes to roughly $10 to $40 or more installed. Concrete overlays run about $3 to $10 and stamped concrete about $8 to $15. The details are in our piece on pavers for saltwater pool. Worth a read next: travertine vs porcelain pavers.
Pavers are the priciest of the three, and the overlay saves the demolition and haul-away. The coping work, drain changes and skimmer collars are extra and belong in the quote. Take the figures as a guide, and get local quotes.
Measure the coping, then pick the paver
If you resurface pool deck with pavers, work in this order. Confirm the slab is sound. Solve the height at the coping. Plan the drains, skimmer lids and flexible joints. Then choose a thin, textured paver that fits the height budget. Skip the tape measure and the pavers will still go down beautifully, right up to the moment they meet the pool.
FAQ
Can you put pavers over an existing concrete pool deck?
Yes, if the slab is structurally sound and the new surface can finish at or below the coping and still slope away from the pool. Thin concrete pavers or 2 cm porcelain keep the added height low.
How thick are pavers for a pool deck overlay?
Thin concrete overlay pavers are commonly around 1 1/4 inches, and 2 cm porcelain pavers are about 3/4 inch. The setting bed adds more, so measure the total against your coping and door heights.
Do I need to replace the pool coping when adding pavers?
Only if the overlay would end up higher than the coping. In that case the coping is usually reset or replaced at the new height on the bond beam, in mortar, with a flexible joint between it and the deck.
Should pavers be glued or sand-set over a pool deck?
Both are used. Sand-set needs drain holes through the slab and a solid edge; adhesive or mortar setting adds less height but needs the surface to shed water to a drain. Follow the paver manufacturer's overlay instructions.
Is it cheaper to resurface a pool deck with pavers or concrete?
Concrete overlays and stamped concrete usually cost less per square foot than pavers. Pavers cost more up front but let you lift and replace individual units later.
