Building a Deck with Deck Blocks: A Comprehensive Guide

Embarking on a DIY deck building project can significantly enhance your outdoor living space. Deck blocks, also known as concrete deck blocks or adjustable deck blocks, are a popular choice for creating a sturdy, level, and long-lasting foundation. This guide will walk you through the process of building a deck with deck blocks, ensuring a solid structure that will withstand the test of time.

Understanding Deck Blocks

Deck blocks are designed to support the weight of your deck while allowing for proper drainage and water flow. They are typically made of concrete and have a flat top surface with a slanted or stepped design on the sides to facilitate leveling. Some deck blocks also come with adjustable features, enabling you to create a perfectly level surface even on uneven ground.

Planning Your Deck Project

Before you begin construction, it's crucial to plan your deck project meticulously. This includes determining the size and shape of your deck, choosing the right materials, and obtaining any necessary permits. Once you have a clear plan, you can gather the required tools and materials:

• Deck blocks
• Pressure-treated lumber for the deck frame and joists
• Decking material (wood, composite, or PVC)
• Gravel and landscape fabric
• Cement and sand (for mortar, if needed)
• Tools: tape measure, level, shovel, wheelbarrow, trowel, rubber mallet, circular saw, drill, and safety gear

Preparing the Site

Begin by clearing the area where your deck will be built, removing any debris, vegetation, or existing structures. Next, mark out the perimeter of your deck using stakes and string. Once you have the layout, calculate the number of deck blocks needed, ensuring you have enough to support the deck frame and joists at regular intervals (usually 16" or 24" on center).

Laying the Deck Blocks

Start laying the deck blocks along the outer edges of your deck, ensuring they are level and square. Use a tape measure and a level to maintain accuracy. For adjustable deck blocks, follow the manufacturer's instructions to set the desired height. As you lay the blocks, create a slight slope away from the house to facilitate water drainage.

After laying the outer edge, fill in the interior with deck blocks, spacing them evenly to support the deck frame and joists. If your deck design includes stairs or other features that require additional support, make sure to place blocks accordingly. Once all the blocks are laid, use a rubber mallet to tap down any high spots and ensure a level surface.

Building the Deck Frame

With the deck blocks in place, you can begin constructing the deck frame. Start by attaching pressure-treated posts to the outer edge blocks, ensuring they are plumb and square. Use galvanized hardware for added durability. Next, install the beam that will support the deck joists, attaching it to the posts with joist hangers or ledger board hardware.

Cut and install the deck joists, spacing them evenly along the beam and attaching them with joist hangers or toenailing. Make sure the joists are level and supported by the deck blocks. Once the frame is complete, you can install the decking material, following the manufacturer's instructions for spacing and installation.

Finishing Touches

After the decking is installed, apply a finish or sealant to protect the wood from moisture and weathering. If desired, you can also install railings, balusters, and other decorative features to enhance the appearance of your deck. Finally, spread a layer of gravel over the landscape fabric beneath the deck to promote drainage and prevent weed growth.

Maintenance and Care

Regular maintenance is essential to keep your deck looking its best and performing well. Inspect the deck annually for signs of damage or wear, and address any issues promptly. Clean the deck regularly to remove dirt, debris, and mold, and apply a fresh coat of finish or sealant every 2-3 years to protect the wood. By following these guidelines, you can ensure your deck built with deck blocks remains a functional and attractive addition to your home for years to come.
