Atienza Permeable Pavement - drains up to 234 l/min and prevents puddles
Atienza Permeable Pavement: the water drains itself away
A garden or terrace that floods after every rainfall, or a slippery pool deck, stops being just a cosmetic issue and becomes a safety one. This slab is porous throughout its entire body and offers a water flow-through capacity of up to 234 liters per minute, so water passes through the pavement instead of pooling on top.
✅ Key advantages
High permeability: up to 234 liters per minute of water flow-through, with no puddles or surface films.
Greater safety: with no standing water on the surface, the risk of slipping is greatly reduced.
Less slope needed: since it drains vertically, it relies far less on a slope towards drains.
Five colors: white, anthracite, natural grey, sand and bronze.
🏗️ Recommended applications
Pool decks and surrounds.
Terraces, patios and roof decks.
Gardens and green areas with poor drainage.
Areas exposed to heavy rainfall.

🧰 Installation
Excavate and prepare a 15-20 cm draining base of washed gravel; without it the slab filters through but the water stays trapped underneath.
Spread a 3-4 cm layer of fine aggregate and level it.
Lay the pieces leaving an open joint of 3-5 mm.
Bed with a rubber mallet and check the level every few rows.
Fill the joints with clean aggregate, never with fine compacting sand.
Sweep dry and avoid sealing the joints with mortar.
📦 Available formats
50 × 50 × 3.5 cm in white, anthracite, natural grey, sand and bronze.
Sold by unit or by full pallet.
💡 Professional tip: the mistake that completely defeats this product is laying it on a solid concrete slab or grouting it with mortar. The slab itself filters, but if there's a waterproof surface underneath, the water gets trapped and ends up coming back out through the joints just like on a standard pavement. Always use a draining base of washed gravel and joints filled with clean aggregate.
