Local Building Codes

Furthermore, it’s essential to take into account local deck building codes and regulations when designing your deck on a slope. Consult with Excel Custom Decks professionals or check with your local authorities to ensure compliance with safety standards and permit requirements. These regulations typically include specifications for railing height, load-bearing capacity, and setbacks from property lines.

Now that we’ve covered some key aspects of designing a deck on a slope, let’s explore the vital elements related to safety considerations in your plan.

Safety Considerations in Plan

When designing and building a deck on a slope, safety should be your top priority. Always consider the inherent challenges of uneven terrain. It’s crucial to incorporate the following safety measures into your deck plan.

  • Foundation Stability: Ensure a solid foundation by taking into account the depth and type of foundations suitable for your slope. The substructure must be securely anchored to prevent shifting or settling over time.
  • Proper Ledger Board Placement: Install the ledger board and ensure it is securely attached to the main structure. The correct placement is vital for distributing the load evenly and preventing the risk of ledger failure.
  • Baluster and Railings: Incorporate sturdy railings and balusters along the stairs and edges of the deck, especially on steeper slopes. These safety features provide essential support and prevent accidental falls. 
  • Beam and Joist Dimensions: Tailor the dimensions of beams and joists according to the measurements and load-bearing requirements of your deck. Adequate support is essential to ensure the structural integrity of the deck on varied terrain.
  • Fastener Selection and Placement: Choose appropriate deck screws and bolts designed for outdoor use, considering the climate in your region. Ensure proper placement of fasteners, especially along the board edges and ledger board, to prevent deck board detachment.
  • Proper Edge and Board Placement: Mindful placement of deck boards is essential. Avoid overhanging edges that could pose a tripping hazard. Ensure that the boards are securely attached to the substructure to withstand the load and environmental conditions.
  • Appropriate Accessories and Equipment: Utilize accessories such as joist hangers to reinforce the connection between joists and beams. In addition, use appropriate safety equipment during construction to prevent accidents or injuries.

Some argue that investing in safety features might add additional costs to your deck construction project. However, it’s important to prioritize the well-being of yourself, your family, and anyone who may use the deck in the future. Taking preventive measures can save you from potential accidents or costly repairs down the line.

Preparing the Site for Building

Before you can begin constructing a deck on a slope, it’s crucial to adequately prepare the site. This involves several important steps to ensure a stable and secure foundation for your deck.

Minor slopes can often be leveled using various leveling techniques, such as grading and compacting the soil. However, if the slope is more significant, additional measures may need to be taken. One option for preparing the site on a steep slope is to use retaining walls. 

Retaining walls help create level areas by holding back soil and preventing erosion. They can be constructed using different materials, including wood, concrete blocks, or stone. It’s important to consult with a professional or engineer to ensure the retaining walls are designed correctly and can withstand the pressure of the soil.

In addition, it may be necessary to clear any vegetation or debris from the area where the deck will be built. This allows for a clean and even surface that can support the construction.

You should also consider any drainage issues that may arise due to the slope. Proper water management is essential to prevent water pooling or damage to the structure. Implement appropriate drainage solutions to divert water away from the deck area. This will help maintain the integrity of your deck over time.

Ground Works: Stilts vs Terracing

When building a deck on a slope, two common approaches for creating level platforms are stilts and terracing. Each method presents unique advantages and considerations. With that a deck installer is important to evaluate these factors based on your landscape and desired outcome.

Stilts

Using stilts involves constructing a series of vertical supports or piers at regular intervals across the slope to elevate and level each section of the deck. This method is suitable for steeper slopes as it allows for maximum flexibility in creating level platforms. Stilts can be made from treated lumber, concrete footings, or adjustable metal post supports. One of the main advantages of stilts is their adaptability to varying slope conditions. This makes them a versatile option for deck construction.

Terracing

Terracing involves creating multiple levels or steps in the landscape. This transforms the slope into a series of flat terraces accommodating different deck sections. Terracing can be achieved by grading and leveling the land or constructing retaining walls at each level. Thus, creating an appealing and balanced integration with the natural contours of the land. Moreover, terracing provides more usable space for landscaping features such as gardens or seating areas.

Both stilts and terracing have their benefits and limitations, and choosing the right method largely depends on factors such as personal preference, budget constraints, local regulations, and the specific characteristics of your property. It’s advisable to consult with a professional deck builder in Wisconsin who can assess your site and provide recommendations based on your preferences.
