Dover White 12˝ Internal 6″ Radius Corner Coping

Elegant Internal Transitions for Sophisticated Pool Design

Internal corner coping serves a unique and critical role in pool installations where the coping turns inward, creating concave corners that require specialized pieces to maintain structural integrity and visual continuity. The Dover White 12˝ internal 6″ radius corner coping provides the perfect solution for these challenging transitions, offering both functional excellence and aesthetic sophistication.

The Dover White range is specifically designed to replace traditional 9″ and 12″ concrete pre-cast coping stones making them the ideal choice for refurbishments as well as newly constructed pools. This internal corner piece with its 6″ radius creates smooth, professional-grade transitions that are essential for pools with spa attachments, curved sections, or complex geometric designs.

Understanding Internal Corner Applications

Spa and Pool Integration

Internal corners are most commonly required where spas attach to main pool structures, creating inward-turning corners that need specialized coping treatment. These transitions must maintain water-tight seals while providing seamless visual flow between different pool sections.

Complex Pool Geometries

Modern pool designs often incorporate curved sections, bay areas, or architectural features that create internal corners. These design elements require precise internal corner pieces to maintain the sophisticated appearance and functionality of the overall installation.

Structural Requirements

Internal corners experience different stress patterns than external corners, with forces concentrating inward rather than outward. The robust construction of Dover White internal corners ensures reliable performance under these unique loading conditions.

Premium Design Features

Optimized 6″ Radius

The 6″ radius provides the ideal curvature for internal corners, creating smooth water flow patterns while maintaining compact dimensions that work within typical pool design constraints. This radius eliminates sharp internal angles that could create turbulence or debris collection points.

12˝ Width Advantages

The substantial 12˝ width provides:

• Enhanced structural support at critical junction points
• Generous surface area for swimmer comfort and safety
• Visual weight appropriate for larger pool installations
• Compatibility with substantial decking materials and designs

Precision Internal Geometry

Internal corner pieces require more complex manufacturing than external corners, as the concave shape must be precisely formed to ensure proper fit with adjacent straight sections. Dover White’s precision manufacturing ensures reliable alignment and installation.

Superior Sandstone Construction

Natural Material Benefits

Available exclusively from Certikin, Dover White coping stones are made from sandstone and are both functional and modern looking. The natural properties of sandstone provide excellent performance in the demanding environment of internal pool corners.

Manufacturing Excellence

They are sawn on all six sides ensuring a flat surface all round making them easy to lay as well as preventing the collection of water and dirt on the surface. This precision is particularly critical for internal corners where any irregularities would be immediately apparent and could compromise water flow.

Optimal Surface Treatment

The surface of each stone is also honed to give a smooth finish however the natural suction of the pores in the stone make it slip resistant – a necessity for pool surrounds. Internal corners often experience concentrated foot traffic, making this slip-resistance particularly valuable.

Technical Performance Characteristics

Hydraulic Efficiency

Internal corners with proper radius design facilitate smooth water circulation around the pool perimeter. The 6″ radius eliminates sharp angles that could create turbulence or dead spots in water circulation systems.

Thermal Performance

The thermal mass of sandstone provides stability in internal corner areas that may experience varying sun exposure throughout the day. This ensures consistent comfort levels regardless of time or weather conditions.

Chemical Resistance

Internal corners often experience concentrated chemical exposure during pool cleaning and maintenance procedures. Dover White sandstone maintains its integrity and appearance despite regular contact with pool chemicals and cleaning compounds.

Sealing and Protection Protocol

Critical Sealing Requirements

Dover White is a very porous material therefore we highly recommend the application of RPB Patio Sealer to ensure it maintains its beautiful finish. Internal corners require particular attention during sealing as water tends to collect and concentrate in these areas.

Enhanced Protection Benefits

By applying this product, it will provide a protective repellent layer to stop staining of the stone from water or oil-based dirt as well as other grime. Proper sealing of internal corners prevents water infiltration that could lead to structural issues or staining in these critical areas.

Maintenance Considerations

Internal corners may require more frequent inspection and maintenance than external corners due to their tendency to collect debris and experience concentrated water exposure. Proper initial sealing significantly reduces long-term maintenance requirements.

Installation and Integration

Alignment Precision

Internal corner pieces must align perfectly with adjacent coping sections to ensure proper water drainage and visual continuity. The precision manufacturing of Dover White ensures reliable fitment when installed by experienced contractors.

Structural Integration

Internal corners serve as anchor points for coping runs, requiring robust construction to handle the structural loads concentrated at these junctions. The substantial construction and precise dimensions ensure reliable long-term performance.

System Compatibility

These internal corner pieces integrate seamlessly with all other Dover White coping components, ensuring consistent appearance and performance throughout complex pool installations involving multiple coping types.

Quality Assurance Standards

Natural Stone Characteristics

Dover White coping stones are made from natural stone therefore there will be variations in colour and texture. These natural variations contribute to the unique character of each installation while maintaining the structural consistency required for internal corners.

Dimensional Verification

To ensure that Dover White copings will be a suitable replacement, please check the dimensions of existing copings and compare with those shown above before ordering. This verification is particularly important for internal corners in refurbishment projects where precise fit is critical.

Professional Installation Standards

It is important the copings are sealed when they are first laid using the recommended product. Internal corners require special attention during installation to ensure proper alignment, sealing, and integration with adjacent coping sections.

Why Choose This Internal Corner?

As a retailer of pool and spa parts, I recommend the Dover White 12˝ internal 6″ radius corner coping for installations requiring sophisticated internal corner treatments. The precision manufacturing and robust construction make this piece essential for pools with spas, curved sections, or complex geometric designs.

The 6″ radius provides optimal water flow characteristics while maintaining the compact dimensions needed for most internal corner applications. The substantial 12˝ width ensures adequate structural support and visual presence appropriate for high-quality pool installations.

Design Applications

Internal corners are essential components for:

• Pool and spa integration points
• Curved pool sections requiring inward transitions
• Bay areas and architectural pool features
• Complex geometric pool designs
• Refurbishment projects replacing damaged internal corners

When combined with external corners and straight sections from the Dover White range, these internal corners enable the creation of sophisticated pool designs that would be impossible with standard 90-degree corner pieces.

Professional Installation Requirements

Internal corner installation requires careful attention to:

• Precise alignment with adjacent straight sections
• Proper support and anchoring at the corner junction
• Thorough sealing to prevent water infiltration
• Verification of proper drainage away from the corner

Professional installation ensures optimal performance and longevity of these critical coping components.
