Can You Put Pavers Over a Concrete Pool Deck? What We Check Before an Overlay

By Tim Niemiec, Owner, American Paving Design

Many homeowners we meet are surprised that their existing concrete pool deck may not need to come out. If the concrete is suitable, an overlay can give them a new surface and a finished pool edge while retaining the slab underneath.

The decision starts with the condition of the concrete, how it drains, and the space available around doors, steps, and adjoining patios. Here is what I look for on the pool-deck renovations we handle in the Lowcountry.

When Can You Overlay a Concrete Pool Deck?

I want a reasonably smooth deck without large, gaping cracks or sections that have heaved upward. I also want good drainage and a slope that carries water away from the house.

In my experience, a deck that has been down for 12 to 15 years without major cracking or heaving can be a good candidate. Its history gives us useful evidence of how it has performed, although it is not a guarantee against future movement.

When Does a Pool Deck Need to Be Removed?

Every overlay adds height. We check what that means at fixed patios, steps, and especially doors. Some steps can be adjusted, but those changes need to be planned before work starts.

One of the most difficult situations is a large sliding door with a threshold set almost level with the existing deck. Adding material can bring the outside surface too high relative to the interior. In that situation, removing the existing deck may be necessary.

How Remodel Coping Covers the Existing Concrete Edge

Homeowners often ask how we hide the old concrete face between the new deck surface and the existing tile. Many manufacturers make L-shaped remodel coping. We cut back the existing cantilevered deck edge above the tile, then mortar-set the coping so its vertical leg covers that exposed face.

We aim to leave the existing waterline tile intact. Our crew takes care with the cuts, but we explain beforehand that accidental tile damage is possible. If a homeowner already wants new tile or plaster, this is a good time to coordinate with their pool contractor.

Pavers, Travertine, or Porcelain for a Pool Deck Overlay

We typically use remodel pavers around 30 mm to 1 1/4 inches thick, or travertine around 1 1/4 inches thick. Travertine may be installed over sand or mortar-set, depending on the project and budget. We typically mortar-set larger porcelain pieces.

We rarely use full-thickness 60 mm pavers over existing concrete. The added height and the difficulty of creating a compatible, attractive coping edge can make them a poor fit for the overlays we encounter.

If a product does not have matching L-shaped remodel coping, we can sometimes use an overhanging bullnose on top and a separate facing piece below it. We have had very few callbacks with that approach, but we explain that movement can affect the separate facing piece.

How We Address Concrete Cracks Before an Overlay

For cracks suitable for treatment, our typical approach uses a flexible crack filler with a membrane over the crack. We consult the membrane manufacturer about compatible materials underneath and follow the selected system requirements. That treatment does not make unstable or heaving concrete suitable for an overlay.

Large pieces of porcelain or stone cannot bend across an abrupt change in slope. We may need to cut pieces into smaller sections so the layout can follow the grade while keeping the pattern coordinated. Those layout cuts are separate from joints intended to accommodate movement.

How We Replace Pool Deck Drains During an Overlay

At the consultation, we ask whether the existing deck drains properly. If the layout works, we often retain the drain location but install a new drain at the higher finished surface. If it does not work, we evaluate the slope and whether a different location or drain size makes sense.

Most of our installations use a three-inch deck drain with a removable top. It gives access for cleaning, and we have had very few issues with the three-inch tops we use. In our experience, some wider plastic tops have been more prone to curling or warping in the heat. Metal grates are another option, at a higher cost.

Hidden Pool Deck Drains and Their Maintenance Tradeoffs

For a less visible drain, we can use manufactured slotted travertine pieces or precisely cut openings in larger stone above the drain channel. Water enters through those openings, with the drain concealed below.

The tradeoff is access. Concealed drains are much harder to clean and repair. For those installations, we use a sufficiently large channel and plan for flushing debris from an accessible end. That approach cannot guarantee every blockage can be cleared. Homeowners who prioritize easy maintenance should consider a removable-top drain.

How We Raise Skimmer Lids and Install Matching Covers

The skimmer access also needs to meet the new deck height. If the homeowner wants a conventional plastic lid, we use a compatible extension or collar and a lid in an available color, typically white, gray, or tan.

For a matching appearance, we can cut a cover from travertine or porcelain and add a lifting hole. We support it on a small concrete surround carried by the existing concrete deck, rather than resting it on the plastic skimmer. These custom pieces can break, so we typically cut two to four matching covers for the homeowner.

We have also used manufactured concealed-cover systems. I explain that a matching or hidden cover may involve more future maintenance. Conventional plastic lids are generally easier to replace and repair, and their available colors work for many homeowners.

Coordinating New Coping, Waterline Tile, and Pool Plaster

On a full renovation, our typical sequence starts with APD cutting back the existing concrete edge. The pool contractor then handles draining, interior preparation, and new waterline tile. APD returns to install the coping, deck surface, and drains. After our hardscape work is complete, the pool contractor returns for the new plaster finish. The pool contractor determines their exact preparation methods.

Hilton Head Pool Deck Overlay: Project Details and Cost

On a recent Hilton Head Island project, the homeowners were concerned that their old concrete deck would need to be removed. We were able to retain it and install a three-piece paver available in a 30 mm thickness, with matching remodel coping.

We adjusted the grading near a step, formed the drainage swale, and coordinated the coping and step elevations. The homeowner also had the waterline tile and plaster replaced by their pool contractor. APD's installation took about four days, including coping, drains, coping grout, deck pavers, and jointing sand. That was our installation time, not the entire pool-renovation schedule.

APD's quoted labor and materials for this specific project were:

APD scope

Project cost

Pool-deck overlay

$18,800

Remodel coping

$4,600

New deck drain

$2,800

Total APD work

$26,200

The pool contractor's tile and plaster charges were separate. This is one project example, not a standard price for every overlay. Retaining the slab avoided full deck demolition and its potential disturbance of buried pool plumbing. It was still a construction project, with dust and disruption, but the homeowners were very happy with the finished result.

FAQ section

Can you put pavers over a concrete pool deck? Yes, if the concrete is suitable. APD looks for a reasonably smooth deck without large cracks or heaved sections, good drainage, and a slope that carries water away from the house.

When does a concrete pool deck need to be removed instead of overlaid? When the added height won't work at doors, steps or fixed patios. A large sliding door with a threshold almost level with the deck is one of the most difficult cases. Unstable or heaving concrete is also not suitable.

How thick are pavers used for a pool deck overlay? APD typically uses remodel pavers around 30 mm to 1 1/4 inches thick, or travertine around 1 1/4 inches thick. Full-thickness 60 mm pavers are rarely used over existing concrete.

How is the old concrete edge hidden after an overlay? With L-shaped remodel coping. APD cuts back the existing deck edge above the tile and mortar-sets the coping so its vertical leg covers the exposed concrete face.

How long does a pool deck overlay take? On a recent Hilton Head Island project, APD's installation took about four days, including coping, drains, coping grout, deck pavers and jointing sand. That did not include the pool contractor's tile and plaster work.

How much did a recent pool deck overlay cost? APD's work on one Hilton Head Island project totaled $26,200: $18,800 for the overlay, $4,600 for remodel coping and $2,800 for a new deck drain. Tile and plaster were separate. This is one example, not a standard price.
