Quick Summary:
La Maison Group’s Sandblasted and Slotted Marble Surface collection combines non-reflective matte textures with precision linear grooving. Engineered via CNC-controlled slotting and high-pressure abrasive blasting, these bespoke fluted stone panels are ideal for modern acoustic-diffusing feature walls, slip-resistant commercial flooring, and minimalist architectural cladding.
Product Overview
Our Sandblasted & Slotted Marble collection is designed for architects who prioritize subtle elegance and tactile rhythm. The Sandblasted finish creates a uniform, micro-textured surface that softens the stone’s color and veining, while the Slotted (Grooved) processing introduces a clean, architectural linear language. This combination is particularly effective for large-scale Bespoke Stone installations where light diffusion and geometric consistency are required to anchor a minimalist or industrial luxury aesthetic.

Key Features
Diffused Matte Sophistication
The sandblasting process removes the stone’s natural gloss, creating a sophisticated matte finish that is completely anti-reflective. This is essential for Project Solutions in high-light environments like glass-walled lobbies, where polished stone would cause distracting glare.
Rhythmic Linear Slotted Geometry
Our CNC-controlled slotting creates perfectly parallel grooves that add a sense of height and order to any space. This Precision Processing allows for customized spacing and depths, enabling the creation of bespoke “Stone Fluting” that integrates seamlessly with modern millwork and metal accents.
Superior Slip Resistance & Safety
Unlike polished surfaces, the sandblasted texture offers exceptional grip. This makes the Sandblasted & Slotted series a primary choice for high-traffic commercial flooring and luxury spa transition zones where safety must meet high-end design.
Structural Integrity & Durability
Despite the deep grooving, our panels maintain high Structural Integrity. We utilize advanced stress-relief cutting techniques to ensure that the slotted ridges remain durable and resistant to impact, backed by fiber-mesh reinforcement for long-term architectural stability.
Industrial Applications
Luxury Hospitality & Retail
Ideal for boutique storefronts and hotel elevator cabs, the linear texture creates a sense of movement and prestige. The anti-fingerprint nature of the sandblasted surface ensures the walls remain pristine in high-touch public zones.
Private Villas & Estates
Used in minimalist master bathrooms or outdoor garden walls, the Bespoke Stone grooves provide a biophilic connection to natural geological strata, blending perfectly with organic landscape elements.
Commercial & Financial Landmarks
In grand lobbies and executive corridors, the slotted panels provide natural acoustic diffusion, helping to dampen sound in expansive marble halls while maintaining a clean, professional “Architectural Line” visual.
Technical & Surface Performance
Our sandblasted surfaces undergo a proprietary Surface Performance sealing process. We apply an oleophobic and hydrophobic nano-coating that penetrates the micro-textured surface, preventing oils and dirt from settling into the sandblasted pores. The Slotted grooves are precision-milled with diamond-tipped tools to ensure no micro-chipping occurs along the edges, resulting in razor-sharp lines that emphasize the architectural geometry of the installation.
Bespoke & OEM Manufacturing
We provide comprehensive OEM Manufacturing for unique slotting profiles. Whether you require V-shaped grooves, U-shaped fluting, or asymmetric spacing, our CAD team can calibrate our CNC machinery to your exact specifications. Our Marble Customization also extends to “Gradient Sandblasting,” where the intensity of the texture can be adjusted across a single panel for artistic effect, alongside precise logo inlays within the slotted matrix.
Production Process
Block Selection
We curate stone blocks with high structural density and uniform background color. For sandblasted projects, consistency is key, as the matte finish will highlight any significant tonal shifts in the raw material.
Digital Cutting & Slotting
Using automated Digital Cutting systems, the slabs are first sized and then moved to our CNC slotting lines. Here, water-cooled diamond blades carve the rhythmic grooves with a constant depth and interval, ensuring 100% pattern alignment across all project panels.
Uniform Sandblasting
Following the slotting, the panels are processed through our high-pressure sandblasting chambers. We use calibrated ceramic or steel grit to achieve a perfectly uniform “frosted” texture that covers both the surface and the interior of the grooves.
Dry-lay Inspection
The final Dry-lay Inspection is conducted in our 16,000m² hall. We align every panel to ensure the slotted lines flow perfectly from floor to ceiling. Only after a laser-alignment check and color-matching audit are the panels crated for secure global transit.
FAQ
1. How do you ensure the slotted lines align across different panels?
We use a Full-Scale Dry-lay Inspection and sequential numbering system. Every panel is laser-calibrated during production to ensure that when installed in order, the linear grooves flow seamlessly without any vertical deviation.
2. Is sandblasted marble harder to clean than polished marble?
While the surface is textured, our Sandblasted & Slotted panels are pre-treated with a high-performance nano-sealer. This creates a barrier that makes the surface easy to maintain with a standard soft brush or vacuum.
3. Can you customize the width and depth of the slots?
Yes. Our Marble Customization service allows for complete control over the slotting profile. We can adjust the CNC bit to create various widths, depths, and spacing intervals based on your architectural drawings.
4. Does sandblasting change the color of the marble?
Sandblasting typically makes the stone appear a few shades lighter and more “muted” than its polished state. This is often preferred for minimalist designs where a soft, pastel-like stone tone is desired.
5. How do you prevent breakage during shipping for deeply slotted panels?
We reinforce every panel with fiber-mesh or aluminum honeycomb backing. Additionally, our Reinforced Packing includes custom foam inserts that sit inside the grooves to provide structural support during transit, preventing any ridge chipping.
