What are clay pavers and klinker?
Clay pavers are paving units made by shaping clay and firing it in a kiln at high temperature. Klinker is the term used in Spain and much of Europe for densely fired clay products, and in English they are often called brick paviors or brick blocks. The defining feature is that the colour is part of the material itself.
Because the colour comes from the clay and the firing, it does not depend on pigments in a thin top layer. Wear and weathering expose more of the same material rather than a different core, which is why clay paving tends to age evenly. The range of tones runs from pale sand through terracotta and red to deep brown and near-black, often with natural variation between units in the same batch.
Clay pavers are covered by the standard UNE-EN 1344, which sets requirements and test methods for products intended for paving. When you compare offers, it is worth asking for the product data that refers to this standard and checking that the units are actually designed for paving, not walling bricks used on the ground.
Where do clay pavers work best on the Costa del Sol?
Clay pavers look most at home beside traditional Andalusian architecture, terracotta roofs and brick details, and in gardens with a Mediterranean planting scheme. They work well on patios, paths, courtyards and drives, provided the product is suitable for the expected traffic.
On a villa with brick arches or a farmhouse with old tiled floors, clay pavers outside can continue the same palette and feel more natural than grey concrete. In small town courtyards they bring warmth to shaded spaces. On drives, a thicker clay paver laid in herringbone on a well-built base can carry cars, although the product data must confirm that it is intended for vehicle use.
If you are weighing clay against other materials, our guide comparing paving materials sets them side by side, and the article on choosing between concrete, stone and clay pavers discusses appearance, maintenance and price factors. Owners who want a brick look at a lower cost often consider coloured concrete block paving as an alternative.
How are clay pavers laid?
Clay pavers are usually laid in a flexible system: a compacted granular sub-base, a screeded grit bed, the pavers set tightly together and jointing sand vibrated into the gaps. Firm edge restraint is essential, because without it the units creep outwards.
- Excavate to the required depth and compact the natural ground.
- Install kerbs or edging on a concrete haunch so the paving has a fixed boundary.
- Spread and compact the granular sub-base in layers, shaping the falls towards drains.
- Screed an even bed of grit over the sub-base without walking on it.
- Lay the pavers in the chosen pattern, mixing units from several packs to spread colour variation.
- Cut edge pieces cleanly and fit them so no tiny slivers are left at the borders.
- Brush in dry jointing sand, vibrate with a protected plate compactor and top up the joints.
Mixing pavers from several packs is particularly important with clay, because firing creates natural shade differences between batches. Laying one pack at a time can produce visible bands of colour across the finished area. Patterns are a matter of taste and use: herringbone for drives, stretcher or basket weave for patios and paths. Our guide to laying patterns illustrates the options.
Why do clay bricks or ceramic tiles lift on a concrete base?
When ceramic tiles or clay units bonded to concrete lift or tent upwards, the cause is usually movement that the surface cannot absorb: thermal expansion, missing movement joints, poor adhesion or moisture under the tiles. It is a bonded-surface problem, different from block paving that sinks.
Outdoor surfaces exposed to direct sun heat up during the day and cool down at night. A rigidly bonded layer of tiles or bricks on a concrete slab, laid without perimeter and intermediate movement joints, has nowhere to expand, so it pushes upwards and debonds. Flexible clay paving on a sand bed avoids much of this risk because the joints themselves accommodate small movements.
If an existing bonded surface has lifted across a large area, it often makes more sense to remove it and lay a flexible paved surface on a proper base; our page on replacing old paving covers that process. If clay paving on sand has instead sunk or rocks underfoot, the cause lies in the base, and the sister site's page on diagnosing why paving sinks explains how that is investigated.
Can old clay paving on a drive be painted or renovated?
A faded clay drive that is still level and intact can be cleaned and, if the owner wants a change of colour, coated. Painting clay pavers changes their character permanently, so it is best considered only when cleaning alone will not give the result you want.
Clay pavers develop moss, algae and dark staining in shaded or damp spots, and a careful pressure clean often brings back much of the original colour. Where a different look is wanted, the renovation method used on our sister site involves cleaning, filling cracks and applying a tinted acrylic resin in two coats, with an optional protective coat. The page on renovating existing pavers explains the process, and we work with Mapei products for that type of work.
Before deciding, it is worth looking honestly at the base. Coating a drive that is already sinking will only make the defects more visible. In that case, a repair or a full relay is the better investment. A quick check of levels and rocking units at the visit usually answers the question.
What affects the cost of clay paving?
The price of the clay units themselves, the format and thickness, the pattern and the base needed for the traffic are the main factors. Clay pavers are typically priced above standard concrete blocks, and complex patterns or many cuts add laying time.

If you already have pavers in mind, include the product name or a photo of the pack so the quote can be based on the actual units. Send us a photo and the approximate m² – free, no-obligation quote.
Frequently asked questions
Is klinker the same as clay paving?
In Spain, klinker refers to densely fired clay products, including pavers. In English the same products are usually called clay pavers or brick paviors. All of them are made from fired clay, so the colour runs through the whole unit rather than sitting in a surface layer.
Which standard applies to clay pavers?
Clay pavers are covered by UNE-EN 1344, which defines requirements and test methods for fired clay products intended for paving. When comparing offers, ask for product data referring to that standard and make sure the units are designed for paving rather than walls.
Do clay pavers keep their colour?
Because the colour is part of the fired clay, it does not wear off as a surface layer can. Dirt, moss and staining can still darken the surface, especially in shade, but cleaning usually restores much of the original tone of clay paving.
Can I drive a car on clay pavers?
Yes, if the pavers are specified for vehicle traffic and laid on a suitable base in an interlocking pattern such as herringbone. The manufacturer's data for the chosen product should confirm its intended use before it is selected for a drive.
Why does my clay paving show stripes of different colour?
Clay pavers vary in shade between firing batches. If pallets are laid one after another without mixing, the batches can show as bands across the surface. Drawing units from several packs at once during laying spreads the variation evenly.
Can I use old house bricks as pavers?
Bricks made for walls are not designed to withstand foot and vehicle traffic and weathering on the ground, and some will crumble or flake. Reclaimed paving bricks can be used if they are sound. We assess any reclaimed material before agreeing to lay it.
Why have my ceramic tiles lifted outdoors?
Outdoor tiles bonded to concrete often lift because of thermal expansion without movement joints, weak adhesion or moisture underneath. The tiles push against each other and debond. Replacing them with a flexible paved surface on a proper base is one way to avoid the problem.
Can clay pavers be laid on a concrete slab?
They can be bonded to a slab with mortar, but movement joints and drainage then become critical. A flexible system on a granular base with a grit bed is often more forgiving. Which approach suits your site depends on use, levels and the existing surface.
Does clay paving need sealing?
Sealing is not required for clay paving to perform. Some owners choose a sealer near outdoor kitchens or to make cleaning easier. Any sealer should be tested on a small area first, because it can change the colour and surface grip.
Can you paint my clay brick driveway?
If the drive is level and sound, it can be cleaned and coated with a tinted acrylic resin, which is a renovation service covered by our sister site. If the drive is sinking or rocking, the base should be repaired first, otherwise the coating will not hide the defects.
