In swimming pool design, precision is not just aesthetic—it is functional and often regulatory. Depth indicators, contrasting edges, 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’s ‘Public Safety Information System’ begins with a carefully prepared drawing.
The water depths must be clearly represented by text with a height that complies with British Standards and are placed in contrasting colours so that pool users can see them.
At the very least, depth markers should be positioned:
• At the pool's entrance
• In areas that correspond to the maximum and minimum depths
• In the centre of flat or uniformly sloping floors
• When the pool's floor profile abruptly changes to a water depth more than 1.35 meters
This information is translated by Spec Tile into precise drawing files which are compatible with waterjet cutting and suitable for the chosen tile.
Important technical considerations include:
• Tile selection (porcelain, ceramic, or stone suitable for its intended environment)
• Tile thickness and structural stability
• Contrast requirements for legibility
• Surface Finish and Slip Resistance.
By resolving these details at the drawing stage, we ensure the final product performs in a demanding aquatic environment.

Precision Waterjet Cutting for Pool Tile Information 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 inserts (e.g., 1.35m etc.)
• Safety Information (e.g., No Diving.)
• Custom logos or facility branding
Because waterjet cutting produces clean edges, the finished base tile and contrasting inserts fit precisely, maintaining durability, visual clarity and consistent safety underfoot when required.

The Consistency and Longevity of Water Jet Cut Depth Markers
Unlike surface-applied markings, waterjet-cut inlays do not peel, fade, or lift, ensuring they last the intended life of the adjoining floor/wall finish.
Surface applied information to floor finishes such as painting can adversely affect the slip resistance of that surface underfoot and is why water jet cut options are superior by guaranteeing the slip resistance being provided. All our depth marker base and inlay tiles are pendulum tested before fabrication to ensure safety underfoot.

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.
