In swimming pool design, precision is not just aesthetic—it is functional and often regulatory. Depth indicators, step markers, and lane markings must be accurate, durable, and clearly visible while still integrating seamlessly with the overall design of the pool environment.
At Spectile, our workflow transforms detailed drawings into waterjet-cut tiles including depth markers, allowing designers, contractors, and pool builders to achieve both compliance and visual quality in finished installations.

Designing Depth Marker Tiles from the Drawing Stage
Every pool marking system begins with a carefully prepared drawing. Architects, pool designers, and contractors typically provide specifications that include:
• Pool depth measurements
• Marker sizes and font
• Placement relative to steps, slopes, and transitions
• Colour contrast requirements for visibility
These drawings are translated into precise CAD files that define each element of the tile system. At this stage, Spectile refines the design to ensure it is compatible with waterjet cutting and suitable for the chosen tile materials.
Important technical considerations include:
• Material selection (porcelain, ceramic, or stone suitable for submerged environments)
• Tile thickness and structural stability
• Contrast requirements for legibility underwater
By resolving these details at the drawing stage, we ensure the final product performs correctly in a demanding aquatic environment.

Precision Waterjet Cutting for Pool Tile Systems
Waterjet cutting is ideally suited for producing detailed tile components used in swimming pools. The process uses a high-pressure stream of water mixed with abrasive particles to cut through tile material with exceptional accuracy.
This allows Spectile to produce:
• Depth number inserts (e.g., 1.2m etc.)
• Step edge markers
• Lane markings and directional indicators
• Custom logos or facility branding
Because waterjet cutting produces clean edges with minimal chipping, the finished pieces fit precisely within surrounding tiles or recesses, maintaining both durability and visual clarity.

Integrating Depth Markers into the Tile Design
A key part of our service is producing depth marker tiles where the markings are built directly into the tile system, rather than applied afterward.
These markers are created using several methods:
• Waterjet-cut contrasting tile inlays
• Precision-cut lettering or numbers
• Inset contrasting strips or shapes
For example, a depth marker may consist of a darker porcelain number precisely cut and inlaid into a lighter background tile. This ensures the marking remains permanent, resistant to wear, and highly visible even after years of use.
Unlike surface-applied markings, waterjet-cut inlays cannot peel, fade, or lift, making them ideal for long-term pool installations.

Supporting Pool Compliance and Safety
Swimming pools often require clear depth indicators to meet safety standards and facility guidelines. Properly manufactured marker tiles help operators comply with these requirements while maintaining a professional finish.
Waterjet-cut marker tiles offer several advantages:
Long-term durability
Inlaid markers remain intact despite constant water exposure, chemicals, and heavy foot traffic.
Consistent visibility
Precision-cut contrasting materials provide strong visual contrast, even underwater.
Accurate sizing and placement
Tiles are produced directly from CAD drawings, ensuring that numbers, letters, and markers meet specified dimensions.
Design flexibility
Markers can be integrated into decorative tile layouts rather than appearing as separate, utilitarian elements.


Manufacturing and Quality Control
Once drawings are approved, Spectile moves into production. Each tile component is waterjet cut according to the CAD files, ensuring that all pieces fit together precisely.
During quality control, we verify:
• Dimensional accuracy
• Clean waterjet edges
• Proper fit of inlaid marker components
• Consistency across the production batch
Tiles are then carefully packaged and labelled to support straightforward identification and installation on site.

Simplifying Installation for Pool Contractors
Supplying pre-cut marker tiles significantly reduces the complexity of on-site work. Instead of installers cutting numbers or markers manually, they receive ready-to-install tile components that correspond directly with the approved drawings.
This approach provides:
• Faster installation
• Reduced cutting on site
• Improved visual consistency
• Lower risk of installation errors
For contractors and pool builders, it means the finished pool markings match the design specification without requiring additional fabrication during installation.

From Concept to Completed Pool
By combining precise CAD drawings, advanced waterjet cutting, and durable inlaid marker systems, Spectile delivers tile solutions tailored for the unique demands of swimming pool environments.
The result is a streamlined process—from design concept to finished installation—where depth markers, safety indicators, and decorative tile features are manufactured with the same level of precision as the pool itself.
At Spectile, our focus is simple: transforming technical drawings into high-performance tile systems that meet the practical, visual, and safety requirements of modern swimming pools.
