Building a Deck on Pier Blocks: Step-by-Step Guide

Building a deck on alevé blocks is a popular and practical way to extend your living space, providing a picturesque setting for relaxation, entertaining, or simply enjoying the outdoors. Unlike traditional concrete or wood foundations, pier blocks offer a more durable, visually appealing, and eco-friendly option for raising your deck to a comfortable height.

Pier blocks, also known as concrete pier blocks or adjustable pier blocks, are designed to elevate structures above the ground, preventing water damage and providing space for ventilation. They are typically made from concrete, which makes them strong, long-lasting, and resistant to rot and pests. Furthermore, pier blocks come in various sizes and styles, allowing you to customize your deck design and meet local building codes.

Planning Your Deck Project

Before you begin construction, it's essential to plan your deck project meticulously. This process involves determining the size and shape of your deck, selecting the appropriate pier blocks, and ensuring your design aligns with local zoning regulations and building codes.

To ensure stability and longevity, it's crucial to choose the right pier blocks for your deck. Consider factors like the size and load of your deck, as well as the height and spacing requirements for pier blocks in your region. Consulting with a local building inspector or a professional deck builder can help you make an informed decision.

Designing Your Deck

Start by sketching out your deck design, including the size, shape, and any additional features like railings, benches, or planters. Consider the available space, desired functionality, and your budget when designing your deck. Additionally, ensure that your design allows for proper drainage and airflow to prevent water-logging and mold growth.

Take into account the intended use of your deck when choosing the materials for the decking and railings. Pressure-treated lumber, composite materials, and tropical hardwoods are popular choices for decking, offering varying levels of durability, maintenance, and aesthetics. For railings, you can opt for glass, metal, or wood to complement your deck design and provide safety and elegance.

Gathering Materials and Tools

Once you have finalized your deck design and chosen the appropriate pier blocks, gather all the necessary materials and tools for your project. In addition to the pier blocks, you will need lumber for the decking, joists, and supports, as well as hardware like screws, nails, and brackets. Other essential tools include a tape measure, level, circular saw, drill, and safety gear like gloves and eye protection.

It's also a good idea to rent or purchase a concrete mixer, as mixing and pouring concrete is often necessary when installing pier blocks and creating a solid footing for your deck. Additionally, consider renting a concrete saw to cut pier blocks to the desired length and ensure a perfect fit for your deck design.

Preparing the Site and Installing Pier Blocks

Before you begin building your deck, prepare the site by clearing any debris, leveling the ground, and ensuring proper drainage. If the site is not already level, use landscape fabric or a rake to create a smooth, even surface to support your pier blocks and ensure the stability of your deck.

Measure the location of each pier block, ensuring they are evenly spaced and aligned with the layout of your deck. Mark the locations using stakes or spray paint, and excavate the area around each pier block if necessary, allowing for adequate settling and filling with concrete.

Setting Pier Blocks

Begin by placing the pier blocks in their designated locations, ensuring they are level and aligned. Use shims or small pieces of wood to adjust the height and level of each pier block as needed. Once you are satisfied with the placement and leveling of the pier blocks, brace them with temporary supports to maintain their position while you proceed with construction.

For added stability, you can fill the interior cavities of the pier blocks with concrete. This process involves mixing and pouring concrete into each pier block, allowing it to harden and create a solid footing for your deck. Ensure that the concrete fills the entire cavity and reaches the top of the pier block, providing maximum support and stability.

Building the Deck Framework

After installing and securing the pier blocks, it's time to start building the framework of your deck. Begin by installing the bearer beams or joists, which provide the foundation for your decking. Ensure that the bearer beams are supported by the pier blocks and properly spaced to allow for the desired decking material and expansion.

Using appropriate hardware, secure the bearer beams to the pier blocks, ensuring they are level and square. Continuing building the framework of your deck by adding supports and stringers as needed, following your original design and local building codes. Inspect your work regularly to ensure that your deck remains level and structurally sound throughout the construction process.

Adding Decking and Finishing Touches

Once the framework of your deck is complete, you can begin laying the decking material. Start at one corner of your deck and work your way across, ensuring that the decking boards are properly spaced and secure. Use appropriate hardware, such as hidden or surface-mounted fasteners, to connect the decking boards to the bearer beams and joists, maintaining a consistent gap between each board.

After laying the decking, install any additional features like railings, benches, or planters, following your original design and construction plans. Ensure that these features are secure and properly spaced, adhering to local building codes and safety regulations. Finally, apply a suitable sealant or finish to the decking, providing protection against moisture, sunlight, and weathering.

Inspecting and Maintaining Your Deck

Regularly inspect your deck for signs of damage, wear, or sagging, and perform routine maintenance to keep it looking its best. Clean the deck surface with a mild detergent and water solution, removing dirt, debris, and any mold or mildew that may have accumulated. Check the condition of the hardware, tightening or replacing any loose or worn-out components as needed.

Inspect the pier blocks periodically, ensuring they remain level and stable. If necessary, raise or adjust the pier blocks as needed to maintain the proper height and level of your deck. By performing regular maintenance, you can extend the life of your deck and ensure it remains a safe and enjoyable space for years to come.

Building a deck on pier blocks is a rewarding project that can greatly enhance your outdoor living experience. With careful planning, high-quality materials, and meticulous construction, you can create a durable, visually appealing deck that suits your lifestyle and complements your home. Embrace the journey, and enjoy the fruits of your labor as you transform your outdoor space into a tranquil oasis.
