The marble permeable stone flooring (also known as stone carpet) is one of the most advanced solutions for both indoor and outdoor applications. It is chosen for its extreme durability, water permeability that prevents water stagnation, and high aesthetic value. However, the success of the project depends on selecting the correct material.
An often overlooked aspect is the granulometry of the pebbles: smaller fractions (1–4 mm) create smoother and more compact surfaces, ideal for indoor environments or pedestrian areas, while larger granulometries (4–8 mm or more) provide greater drainage capacity and a more natural visual effect, perfect for gardens, pathways, and pool edges.
Another important aspect is that the porous structure of the system allows rainwater to filter into the ground, helping reduce surface runoff and improving sustainable water management. This makes permeable stone flooring an eco-friendly solution increasingly used in modern architectural projects.
Below is a practical calculator for estimating the approximate amount of marble pebbles required for your permeable stone flooring project. This tool allows you to quickly and easily determine the indicative material volume.
Important calculation note: The calculator is based on a standard thickness of 10 mm. To obtain the real material requirement for a high-performance permeable stone flooring, multiply the result by the project thickness:
- Outdoor (Polyurethane Resin): Polyurethane binders are essential due to their resistance to UV rays and thermal changes in permeable stone flooring systems.
- Driveways: For vehicle traffic, the permeable stone flooring layer must be 60 mm thick.
- Pedestrian Areas: For walkways and paths, 30 mm thickness is sufficient.
- Indoor (Epoxy Resin): Epoxy resin is recommended for indoor applications due to excellent adhesion. Ideal thickness ranges between 6–8 mm.
Always verify the mixing ratios of pebbles and resin specified on each product packaging to ensure the structural integrity of the permeable stone flooring.

Technical Comparison: 1–4 mm vs 4–8 mm Granulometry
In addition to color, the size of the pebbles determines the functionality and load-bearing capacity of each permeable stone flooring system. Key differences include:
| Feature | 1–4 mm Granulometry | 4–8 mm Granulometry |
|---|---|---|
| Visual Effect | Smooth, compact, velvety surface. | Bold, natural, three-dimensional texture. |
| Ideal Use | Indoor spaces, balconies, barefoot relaxation areas. | Driveways, outdoor paths, terraces. |
| Drainage Capacity | Excellent for standard slopes. | Excellent, ideal for heavy rainfall. |
2026 Trend: Combining both granulometries allows fine grains to fill the gaps between larger stones, increasing mechanical stability and creating a unique visual depth for permeable stone flooring systems.
Overview of MarmiMax Textures and Shades
In our sample gallery, the range is divided into three macro-categories to simplify the design of your new permeable stone flooring:
- Warm tones (Ochre and Gold): Perfect for creating a welcoming atmosphere. They pair beautifully with wood and lush gardens.
- Modern mixes (Grey, Beige, White): A universal and practical solution. They better hide dirt and suit contemporary architecture.
- Classic White and Pastels: Maximize brightness and visually enlarge small spaces such as entrances or verandas.

FAQ: Frequently Asked Questions about Pebble Flooring
How permeable is MarmiMax stone flooring?
Our systems allow immediate water drainage into the subsoil, eliminating puddles and reducing slip risk.Can it be installed over existing surfaces?
Yes, marble pebbles mixed with resin can be applied over stable screeds or existing flooring.What maintenance is required?
