When you choose La Lastra, you’re choosing a slab format that brings outdoor spaces to life. Fewer joints, larger visible surface, and refined finishes that feel upscale yet built for the job site. These are not your standard pavers; they’re large‑format slabs designed for patios, terraces, walkways and even pool decks where the look of expansive stone is desired. According to Western Interlock: “La Lastra is a three‑piece family of slabs… the flat surface, beveled edge, and elegant proportions are perfect for use in social spaces."

At American Stone, we carry La Lastra because it gives contractors and weekend warriors alike a product that looks premium and installs with fewer seams, but still with the strength and reliability our clients expect.

Pro Tips from American Stone

With large slabs, substrate flatness is essential, aim for < ⅛″ deviation over 10 ft for top‑tier appearance.
Order 10–15% extra material for cuts, blending and layout flexibility.
Mix cartons from the same color blend to avoid visible banding, large slabs make repetition obvious if not blended.
Use appropriate lifting/handling, large square pieces weigh ~94 lbs, so plan manpower or equipment accordingly.
For pool‑deck use, ensure proper drainage, edge restraint and slip‑resistant joint fill; aesthetics matter, but safety and durability are non‑negotiable.
