Tips & Information
At IZU Concept, we are specialists in high-quality cast floors tailored to the Spanish climate. Whether it’s a stylish bathroom, a sunny terrace, or a pool area—our lava stone and quartzite floors are fully waterproof, UV-resistant, and low maintenance. This makes them perfect for bathrooms, kitchens, and pool finishes, blending beautifully with the rest of your outdoor space.
Are cast floors waterproof?
A common question we get is: “Are cast floors waterproof?” The answer: not always. Many traditional cast floors like béton ciré require an additional coating to remain waterproof. Over time, this coating wears down, increasing the risk of leaks.
At IZU Concept, we use Lava stone and Quartzite natural materials that are inherently waterproof. Thanks to their volcanic origin, these cast floors are extremely strong, wear-resistant, and resistant to moisture and UV radiation. They offer a seamless and durable finish without the need for joints or extra protective layers.
Cast floors for pool finishes
Did you know our waterproof cast floors are not only suitable for bathrooms, indoor floors, and terraces, but also ideal for pool finishes? Because the material is fully waterproof and UV-resistant, it’s the perfect solution for modernising swimming pools in Spain.
Outdated pools are transformed into modern Mediterranean showpieces with our lava stone or quartzite flooring. By using the same seamless floor for both the pool and the terrace, you create one harmonious whole—stylish, practical, and low maintenance.
A modern pool renovation in Mediterranean style
Does your pool need a refresh? Our floors are the perfect solution. We apply the finish seamlessly to the bottom and sides of the pool, creating a sleek, aesthetic result that resists sunlight, chlorine, salt, and cleaning products.
Say goodbye to loose tiles, worn joints, or uneven surfaces. With our cast floors, your pool becomes a space to be proud of—perfectly matching the Mediterranean vibe of your home.
Comfort and style – indoors and out
Our cast floors feel pleasant underfoot and adapt to the surrounding temperature. In summer they stay cool, and in winter they combine perfectly with underfloor heating. What’s more, our floors can be seamlessly extended to walls, furniture, and pool edges—creating calm, unity, and a luxurious appearance both indoors and out.
From a Japandi-style bathroom to a luxurious outdoor spa: with IZU Concept, you can turn any space into a stylish whole.

Frequently Asked Questions
Can’t find the answer to your question? Visit the FAQ page or get in touch.
Can a cast floor be applied directly over tiles?
Yes, a cast floor can be applied directly over tiles. We begin by applying a thin, solid layer of cement to create a smooth foundation, then build up our cast floor system with five carefully applied layers.
How long does it take to apply a cast floor?
Installing an IZU floor takes 5–7 days, followed by a drying period. 48 hours after the work is finished, you can step on it on socks. The floor will need a week before furniture can be placed. In total, the house needs to be empty for 2 weeks.
Is an IZU® cast floor a better alternative than microcement?
Unlike microcement, IZU floors are highly resistant to scratches, UV light, and water, making them ideal for both indoor and outdoor use. Their superior strength comes from a specialized material composition based on resin and hard minerals. With the right base, our floors are built up in five layers of ultra-durable material, ensuring a flawless and long-lasting finish.
What is the thickness of an IZU® cast floor?
Our floors are only 2-3 mm thick, excluding the leveling layer. This layer might need to be applied to smoothen the surface. The thickness of this layer depends on the surface below.
Is an IZU floor suitable for outside?
Yes! Our floors are UV- and waterproof, and therefore perfect for your pool area, terrace, and patio. Our floors are very easy to keep clean, will keep their color and don’t stain.
What happens if coffee or wine spills on an IZU® cast floor?
Absolutely nothing! Our floors are protected with an antibacterial, stain-resistant resin that prevents any dirt or liquid from being absorbed. Just wipe away the spill with a damp cloth, and it will look like it never happened.
