Granitic paving slab and sett - Exposed aggregate in grey, pink, sepia and black
Granitic paving: the classic exposed aggregate floor
Granitic paving, also known as exposed aggregate or washed concrete, is a concrete slab whose visible face is washed before it fully sets to leave the aggregate on show. That exposed stone is what gives it its grip underfoot and what lets it take decades of sun, rain and footfall without visible wear. It is the classic surface for pavements, patios and pool surrounds.
✅ Advantages
Exposed aggregate: the surface is grainy rather than smooth, so it grips even when wet and hides dust, stains and scuffs.
Ages well: because the colour comes from the stone itself and not from a coat of paint, a knock or a scrape never leaves a bare patch of a different colour.
Four aggregate colours: grey, pink, sepia and black.
Slab and sett from the same family: the floor and its edging are solved without changing texture.
Matching sett: the 24 x 12 x 6 cm granitic sett lets you build borders, edges and walkways with the same finish as the slab. For now it is supplied on request: write to us and we will send you price and lead time.
🏗️ Applications
Pavements, squares and pedestrian areas.
Patios, terraces and porches.
Pool surrounds and wet areas.
Garden paths and walkways.
Pedestrian access and ramps.
📋 Formats and colours
Slab 40 x 40 x 4 cm — grey, pink, sepia and black. Pallet of 17.92 m² · 88 kg/m².
Slab 50 x 50 x 4 cm — grey, pink, sepia and black. Pallet of 12.00 m² · 90 kg/m².
Sett 24 x 12 x 6 cm — grey, pink and black. On request.
4 cm thick, pedestrian use: for areas with vehicle traffic, ask us before ordering.
Black costs slightly more: its aggregate and pigment are more expensive than the other colours.
Same price per metre, different pallet price: the 40x40 pallet holds 17.92 m² and the 50x50 pallet holds 12.00 m²; that is why they cost different amounts — it is not a price change, they simply do not hold the same metres.
Pallets: the 40x40 pallet is charged at €14/unit and refunded at €13/unit when returned in good condition; the 50x50 pallet is non-returnable.
The range also includes other granitic slab formats. Not every colour is made in every format: the store only shows the combinations the manufacturer supplies.
🧰 Installation
Prepare and compact the base and leave a drainage slope of 1-2% towards the drain or away from the house. Without a slope, water sits on the surface.
On a concrete base, spread exterior tile adhesive with a notched trowel. On ground, lay a 3-5 cm bedding mortar layer levelled off with a straightedge.
Lay out a full dry row before fixing anything, to adjust the layout and decide where the cuts fall: always against the edges, never in the middle.
Bed each piece with a rubber mallet and check the level with a long straightedge every two or three slabs.
Leave a 3-5 mm joint between pieces. Concrete expands in the heat and, laid tight, it chips along the edges.
Grout after 24-48 hours with exterior mortar and remove the residue before it sets on the aggregate: on exposed aggregate, grout dried into the grain is very hard to get out.
💡 Pro tip: with exposed aggregate, what ruins the job is almost always the grouting, not the laying. Work in small sections, wipe with a damp sponge before the mortar pulls and never let it dry on the grain. And order 5-7% extra material in a single batch: the aggregate shifts in tone between batches and topping up half a pallet six months later never matches. When laying, open three or four pallets at a time and mix the pieces, or the floor will come out patchy.
