Sedimentary Limestone

The pool deck and outdoor living stone — warm, cool underfoot, and naturally beautiful.

Travertine is a form of terrestrial limestone deposited by mineral springs, particularly hot springs. Its characteristic voids (pores and channels) form as carbon dioxide escapes during deposition. The stone has been used for millennia — the Colosseum in Rome is built largely of travertine.

Surface options

Tumbled

Edges and surface abraded to a natural, aged look. Maximum slip resistance. Best for pool decks and patios.

Honed

Flat, matte surface. Popular for interior floors and walls. Requires sealing.

Filled & Honed

Voids pre-filled, then honed flat. Easiest to maintain. Most popular interior format.

Brushed

Wire-brushed to create texture and depth. Good for exterior walls and feature applications.

Pros & cons

Advantages

  • Stays cool in direct sun — best pool deck performance
  • Natural slip resistance (tumbled/brushed finish)
  • Resistant to salt and chlorine systems
  • Elegant, warm Mediterranean aesthetic
  • Easy to repair — individual pavers replaceable
  • Good freeze-thaw performance (dense grades)

Considerations

  • Natural voids require filling — upkeep if fill degrades
  • Softer than granite (Mohs 4–5) — can chip on edges
  • Requires annual sealing outdoors
  • Polished finish not appropriate for wet/exterior use
  • Higher water absorption than granite (needs proper sealing)

Travertine — common questions

Travertine's characteristic pores and channels form naturally during deposition as CO₂ escapes. "Filled" travertine has these voids pre-filled at the factory with epoxy or grout. "Unfilled" travertine shows the natural holes. For most applications (floors, pool decks), filled and grouted travertine is recommended to prevent dirt and algae accumulation.
Yes — travertine is the premier pool deck stone. It stays cool underfoot (up to 12°F cooler than concrete pavers) because its lighter color and porous surface reflect rather than absorb heat. Its natural surface texture provides slip resistance when wet. It's resistant to salt-chlorine systems and tolerates the outdoor conditions Florida and Arizona pools require.
Travertine's freeze-thaw rating is "Excellent" for dense grades (C1364 rated). The key is to fill all voids, seal with a penetrating sealer annually before winter, and ensure good drainage so water doesn't pool and freeze on the surface. Thicker pieces (2cm+) perform better than thinner ones. Verify freeze-thaw compliance with your supplier before specifying in USDA Zone 6 or colder.
Filled travertine has the natural voids pre-filled at the factory (usually with epoxy or grout) and then honed or polished smooth. It has a flatter, more uniform surface. Unfilled travertine shows the natural holes — a more rustic, authentic look. Most filled travertine is also "honed" or "polished." Tumbled travertine is typically unfilled, showing its natural character.
Travertine is one of the most affordable natural stones. Material runs $7–$15/sq ft for standard pavers (filled, honed). Premium grades and large formats run $12–$22/sq ft. Installed pool deck with travertine pavers typically runs $15–$25/sq ft total, including material, base preparation, and installation.

How to Maintain a Travertine Pool Deck

Seasonal maintenance schedule for travertine pool decks to ensure long-lasting beauty and safety.

1

Weekly rinse

Rinse the deck with fresh water (hose) weekly to remove salt, chlorine residue, sunscreen, and organic matter. This is especially important for salt-water pool systems, which accelerate surface deterioration if left on the stone.

2

Monthly cleaning

Clean with a pH-neutral stone and tile cleaner diluted per label directions. Use a stiff brush on grout lines. Rinse thoroughly. For biological growth (algae, mold), use an oxygen bleach solution, not chlorine bleach.

3

Inspect and refill voids

Inspect grout-filled voids annually. Freeze-thaw cycles or pool chemical exposure can degrade fill material over time. Re-grout any voids that have opened using matching colored grout.

4

Annual sealing

Apply a penetrating impregnator sealer formulated for exterior and wet environments before the end of summer or start of winter. Apply to clean, dry stone. Allow absorption (10 min), wipe excess, cure 24 hours before foot traffic.

5

Repair settled pavers

Travertine pavers installed on sand can shift or settle. Lifted or rocking pavers are a trip hazard. Re-set by removing the paver, adding or removing sand, and re-bedding in position. Polymeric sand fills joints and resists washout better than regular sand.
