Stone or concrete at the water's edge: how the two really compare

What exactly are we comparing?

We are comparing three families of surface for a pool surround: natural stone slabs or crazy paving, manufactured concrete slabs and pavers laid on a bed, and poured concrete, including stamped or imprinted concrete. They look different, are built differently and age differently.

Natural stone slabs for external paving fall under UNE-EN 1341, while concrete paving blocks fall under UNE-EN 1338 with the Spanish complement UNE 127338. Poured concrete is a site-made slab rather than a product with its own paving standard. Knowing which family you are looking at helps you ask the right questions of a supplier.

Which grips better when wet?

Neither family is automatically safer. Grip depends on the specific product and its finish, which is why the Spanish Building Code works with declared slip classes rather than material names. For pool surrounds within its scope, it requires class 3.

With stone, the finish varies enormously: a riven or flamed face behaves very differently from a honed one. With concrete slabs, manufacturers offer textured outdoor ranges with declared properties. Poured concrete depends on how its surface was finished on site. In all cases, ask for the declared class of the exact version you will walk on. Our guide to pool surround materials explains the classes and the surround width the code asks for.

Which is more comfortable for bare feet?

Comfort for bare feet depends mainly on colour, texture and joint width. Light colours generally stay more pleasant underfoot in strong sun than dark ones, whatever the material. Very rough textures grip well but can feel harsh; very wide joints are less comfortable to walk on.

• Lighter tones are usually preferred around pools for comfort underfoot.
• Moderate texture balances grip and comfort better than extremes.
• Narrow, well-filled joints feel better than wide open ones.
• Crazy paving with tight joints is more comfortable than with wide ones.

We do not make claims about how a specific product behaves in heat; ask the supplier, and if possible stand on a sample in the sun before deciding.

How do they compare on appearance?

Natural stone wins on individuality: every piece is different and the surface looks rooted in the garden. Concrete slabs win on consistency: uniform sizes, chosen colours and clean lines that suit modern villas. Poured concrete gives a seamless surface, and stamped concrete imitates a pattern on that surface.

Appearance also includes how the surround relates to the house and the terrace. Using the same family of material on the terrace and around the pool gives a calm, unified look; contrasting them, for example concrete slabs on the terrace and stone around the water, can frame the pool as a feature. Either works if the levels and joints are handled carefully.

Which is easier to repair?

Concrete slabs and pavers laid on a bed are the easiest to repair: affected pieces are lifted, the base corrected and the same pieces relaid. Natural stone on a bed can be handled the same way, though matching new pieces may be difficult. Bonded crazy paving and poured concrete are the hardest to repair invisibly.

Settling next to the coping is the most common repair on pool surrounds. On a flexible pavement it is a local job; on a poured slab it may mean cutting out and recasting a section. Our sister site explains lift and relay for flexible paving that has dropped.

If an existing stamped concrete surround is sound but faded, it can often be renewed without replacement through cleaning, crack filling and a tinted resin applied in two coats. That is the work of our sister site for stamped concrete restoration, and we work with Mapei products for it.

How do they age and what upkeep do they need?

Stone weathers and develops a patina, which many owners like, but porous stones can absorb stains from leaves, suncream or barbecue grease. Concrete slabs fade gradually and their joints need topping up. Poured concrete can crack and its surface can wear or discolour.

Routine care is similar for all three: sweep, rinse, deal with spills quickly and keep drains clear. Our guide on looking after outdoor paving covers the routine, including what not to do with a pressure washer.

How does each option meet the coping?

Each option meets the coping differently. Stone surrounds are often paired with a matching stone coping, which gives a seamless edge but makes the coping choice part of the stone order. Concrete slab surrounds can be combined with manufactured coping units or with an existing coping that stays. Poured concrete usually runs up to a coping that is already in place.

• Stone with stone coping: unified look, order both from the same batch.
• Concrete slabs with existing coping: the surround is set to the coping level.
• Poured concrete: the joint between slab and coping has to be detailed carefully.
• In every case, the fall starts at the coping and runs away from the water.

Because the coping belongs to the pool structure, we always confirm in advance who supplies and fixes it. That single decision affects the order, the levels and the sequence of the whole job.

So which should you choose?

Choose natural stone if character and a natural garden feel matter most and you accept some variation and more careful upkeep. Choose concrete slabs or pavers if you want consistency, easy repairs and a wide choice of modern looks. Poured concrete suits simple layouts where local relaying is not a priority.

If you are leaning towards stone, our post on whether natural stone by the pool is right for you looks at who it suits best. Our service pages for pool surround paving and paved terraces describe how we build stone and slab surrounds; we also pour new stamped concrete where that layout suits it.
