Why Choose Cumaru Deck Tiles for a Courtyard?
Cumaru deck tiles are crafted from tropical hardwood, known for their rich reddish-brown grain and robust character. This material offers a natural warmth and aesthetic appeal that can soften the look of a hardscaped courtyard. The pre-assembled tile format simplifies installation compared to traditional decking boards, making them suitable for DIY projects or professional installation over existing flat, stable surfaces.
Their visual depth and warm tones can create a sophisticated backdrop for outdoor furniture and landscaping, enhancing the overall ambiance of your courtyard.
Cumaru deck tiles are available in two primary sizes: 12 x 12 inches and 24 x 24 inches. The choice of size impacts the visual scale of your courtyard and the number of seams. A 12 x 12-inch tile covers 1 square foot, while a 24 x 24-inch tile covers 4 square feet. The larger format can create a more expansive feel, while smaller tiles might be preferred for intricate layouts or smaller courtyards.
Defining Your Courtyard Gathering Zones
Before selecting your tiles, consider how you intend to use your courtyard. A gathering area often benefits from distinct zones. For example, you might want a dining area, a lounge space with comfortable seating, or a quiet corner for reading. Sketching these zones onto a plan of your courtyard will help you visualize the layout and identify any specific needs.
Think about the flow of traffic between these zones and how Cumaru deck tiles can define them. You might use the same tile throughout for a cohesive look or incorporate different patterns or even other materials (like decorative gravel or stepping stones) to subtly delineate areas. The goal is to create functional spaces that encourage interaction and relaxation.
Consider existing features like walls, planters, or fixed seating. These elements will influence your tile layout and may require careful cutting or planning around. Ensure that any doors or pathways remain clear and that the finished tile surface does not impede access.
Planning Your Tile Layout and Quantity
Once your zones are defined, measure your courtyard accurately. For a rectangular area, measure the length and width. For irregular shapes, break the area into smaller, measurable rectangles. This step is critical for estimating the number of tiles needed.
Let's consider a hypothetical courtyard measuring 10 feet by 15 feet, totaling 150 square feet. If you choose 24 x 24-inch Cumaru deck tiles, each tile covers 4 square feet. To cover 150 square feet, you would initially calculate 150 / 4 = 37.5 tiles. However, direct division is not sufficient for ordering. You need to account for cuts and waste.
For a 10-foot by 15-foot area using 24-inch (2-foot) tiles: The 10-foot side requires 10 / 2 = 5 tiles. The 15-foot side requires 15 / 2 = 7.5 tiles. Since you cannot purchase half a tile, you will need 8 tiles for the 15-foot dimension. Therefore, you would need 5 tiles x 8 tiles = 40 tiles. This approach ensures you have full tiles for the majority of the area and allows for necessary cuts.
Always add an allowance for waste, typically 5-10%, especially if your courtyard has an irregular shape or many cuts are anticipated. For this example, 40 tiles + 10% waste (4 tiles) means ordering 44 tiles to ensure you have enough material, including spares for future repairs or unexpected cuts. For intricate layouts, a more detailed cut plan may be beneficial.
Consider the visual impact of your chosen tile size. Larger 24 x 24-inch tiles can make a smaller courtyard feel more expansive by reducing the number of visible seams. Smaller 12 x 12-inch tiles might be better for very irregular shapes or to create a more intricate grid pattern.

Substrate Requirements and Drainage
Cumaru deck tiles are designed to be installed over a flat, stable, and well-drained substrate. Common substrates include concrete patios, existing pavers, or compacted gravel bases. The surface must be level to ensure a consistent and safe walking surface. Any significant dips or humps should be addressed before installation.
Proper drainage is essential to prevent water accumulation beneath the tiles, which can lead to issues with the substrate or the tiles themselves over time. Ensure that your courtyard has a slight slope away from any structures (typically 1/8 to 1/4 inch per foot) to allow water to run off. If the existing surface does not have adequate drainage, you may need to consult with a professional about grading or installing a drainage system.
If installing directly on a concrete slab, ensure the concrete is clean and free of debris. For installation over gravel, a compacted base with a weed barrier is recommended. The method of attachment or support for the tiles will depend on the chosen substrate and desired height, such as using deck tile connectors or adjustable pedestals.
Complementary Products and Finishing Touches
To complete your courtyard gathering area, consider complementary products. Edge pieces or trim can provide a finished look, especially if the tiled area is raised or exposed on all sides. These can be made from Cumaru lumber or a contrasting material.
Outdoor furniture, such as dining sets, lounge chairs, or benches, will define your gathering zones. Look for pieces that complement the reddish-brown tones of Cumaru. Planters with greenery can add natural elements and soften hard edges, while outdoor lighting can extend the usability of your courtyard into the evening.
Consider adding privacy screens or pergolas to enhance comfort and define the space further. For a modern aesthetic, explore Ipe deck tiles or Garapa deck tiles, which offer deep chocolate tones and warm golden hues, respectively, if you wish to consider other tropical hardwood options. These choices can create a distinct visual contrast or complement the Cumaru.
Remember that the beauty of Cumaru can be preserved with periodic cleaning and, if desired, the application of a UV-protectant finish to maintain its original color. Without treatment, Cumaru will naturally weather to a silver-gray patina over time.
Before you order
- Measure your courtyard accurately for length, width, and any irregular areas.
- Define specific gathering zones (e.g., dining, lounging) and their dimensions.
- Determine the desired tile size (12 x 12 inch or 24 x 24 inch) based on aesthetic and layout complexity.
- Calculate the total square footage and estimate the number of tiles, including a 5-10% waste factor.
- Assess the existing substrate for flatness, stability, and proper drainage.
- Plan for any necessary cuts around obstacles, edges, or for specific patterns.
- Consider complementary elements like furniture, planters, lighting, and edge finishing.
- Review local building considerations or homeowner association guidelines, if applicable.
Confirm installation details, approved uses and warranty terms in the current instructions for the exact product and profile. Your installer should verify the substrate, structure and applicable project requirements.
Questions to help you decide
How do Cumaru deck tiles attach to each other?
Cumaru deck tiles typically feature a plastic grid backing with interlocking tabs or connectors. These connectors allow the tiles to snap together securely, creating a stable surface. Specific attachment methods can vary by manufacturer, so always refer to the product documentation for the exact assembly instructions.
Can Cumaru deck tiles be installed directly on grass or dirt?
No, Cumaru deck tiles should not be installed directly on grass or bare dirt. They require a flat, stable, and well-drained substrate, such as a concrete slab, existing patio, or a properly prepared and compacted gravel base. Installation over uneven or unstable surfaces can lead to an unsafe and unstable finished deck.
Do Cumaru deck tiles require maintenance?
Like most natural wood products, Cumaru deck tiles benefit from periodic maintenance to preserve their appearance and longevity. This typically involves regular cleaning to remove dirt and debris. To maintain the original reddish-brown color, a UV-protectant finish can be applied periodically. Without such treatment, Cumaru will naturally weather to a silver-gray patina over time. Always follow the manufacturer's recommendations for specific care and maintenance.
