Understanding Total Build-Up for Deck Tiles
The 'total build-up' refers to the combined height of all components that make up your deck tile system, from the existing sub-surface to the top of the finished tile. This includes the tile itself, any underlying support structures like pedestals or sleepers, and potentially a drainage mat or protective membrane.
Garapa deck tiles are available in two standard dimensions: 12" x 12" and 24" x 24". The thickness of the tile itself is a primary component of the build-up. When planning, you must account for this thickness, plus any support system you choose, to determine the final height of your new surface. For example, if using a pedestal system, the adjustable height of the pedestals will significantly contribute to the total build-up.
Identifying Your Door Threshold Type
Door thresholds typically come in various forms, each presenting different clearance challenges. Common types include raised thresholds, flush thresholds, and sliding door tracks. A raised threshold, often seen with exterior hinged doors, creates a lip that the door clears. Flush thresholds, common with some modern sliding or bifold doors, offer a more seamless transition.
It is essential to identify the type of door and its threshold to understand how it functions. Measure the distance from the finished floor inside to the top of the threshold, and critically, the clearance from the top of the threshold to the bottom edge of the door when it is fully open or swung.
The Importance of Door Swing and Operation
Beyond just the static height of the threshold, consider how the door operates. A hinged door swings inward or outward, requiring clearance for its entire arc. If the new deck tile surface is too high, the door's bottom edge may scrape, or the door may not be able to open fully.
For sliding doors, the primary concern is the height of the track and whether the new deck tile surface will impede the sliding mechanism or create an uneven step. Bifold doors also require careful consideration of their folding action and any hardware that might extend below the door panels.
Worked Example: Planning for a Hinged Door
Let's consider a hypothetical scenario: you are installing 24" x 24" Garapa deck tiles on a concrete patio leading to a hinged exterior door. The existing concrete patio is relatively flat. You plan to use a low-profile pedestal system to allow for drainage and minor leveling.
Let's assume this measurement is 1.75 inches.
2. **Measure Threshold Height:** Measure the height of the door's threshold. For this example, let's say the threshold is 0.75 inches above the concrete patio surface.
If the door's bottom edge is 1.75 inches from the concrete and the threshold is 0.75 inches high, then the maximum height for your deck tile system (including the tile and any support) before it interferes with the door is approximately 1.75 inches. This allows for minimal operational clearance.
4. **Calculate Deck Tile Build-Up:** A standard 24" x 24" Garapa deck tile typically has a thickness of approximately 1.25 inches. This might be acceptable, but some prefer slightly more space.
Another option, if feasible, might be to adjust the door's height, though this often involves more complex carpentry.
Considerations for Accessibility
When planning any outdoor surface, especially near entry points, it is important to consider accessibility. Steep steps or significant height differences between the indoor and outdoor surfaces can create barriers. Depending on local building codes and specific project requirements, there may be regulations regarding maximum threshold heights and ramp slopes for accessible routes.
While Garapa deck tiles can create beautiful, functional surfaces, ensure your design complies with any applicable accessibility standards, especially for commercial or public-facing projects. Consult with your design team or local building authority for specific requirements.
Complementary Products for Your Deck Tile Project
Once you have confirmed your threshold clearance, consider other elements that will enhance your Garapa deck tile project. For larger areas or situations requiring more robust support and leveling, exploring different pedestal systems is beneficial. These systems can accommodate varying heights and provide a stable base. You can find more information on various deck tile options, including Ipe and Cumaru, which offer different aesthetic profiles and characteristics, at our main deck tiles page. For projects requiring a specific look, exploring the distinct rich reddish-brown grain of Cumaru or the deep chocolate tones of Ipe may offer alternative design directions. For edge treatments, consider trim pieces or transition strips that can create a clean finish where the tiles meet other surfaces or drop off to a lower level.
Before you order
- Measure the existing surface height relative to the door's bottom edge.
- Measure the height of the door threshold.
- Determine the minimum desired clearance between the door and the new deck surface.
- Identify the thickness of your chosen Garapa deck tile (e.g., 12" x 12" or 24" x 24").
- Account for the height of any chosen support system (pedestals, sleepers, drainage mat).
- Calculate the total build-up: (tile thickness) + (support system height).
- Compare the total build-up to the available door clearance.
- Verify door swing or sliding operation is unimpeded.
- Check for any applicable accessibility requirements regarding threshold height.
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
What if my planned deck tile height is too high for the door?
If your calculated deck tile system height is too high, you have a few options. You could explore lower-profile pedestal systems or alternative support methods. Another possibility, if feasible, is to adjust the door's height by re-hanging it or trimming its bottom edge, though this often requires professional carpentry. In some cases, a ramp or transition piece might be used, but this must be carefully considered for functionality and accessibility.
Do Garapa deck tiles need a gap at the threshold?
Yes, it is generally recommended to leave a small expansion gap where the deck tiles meet any fixed structure, including door thresholds. This gap allows for natural expansion and contraction of the wood due to temperature and humidity changes, helping to prevent buckling or damage. The specific size of this gap can depend on the manufacturer's recommendations for your chosen support system and local climate conditions.
Can I use Garapa deck tiles on a sloped surface near a door?
Garapa deck tiles, especially when installed with adjustable pedestal systems, can be adapted to create a level surface over a sloped sub-surface, such as a concrete patio with a slight pitch for drainage. However, careful planning is needed to ensure the final level surface meets the door threshold correctly while maintaining proper drainage beneath the tiles. Always ensure that the underlying slope still allows water to drain away from the building's foundation and door opening.
