Step-by-step Instructions for How to Use Concrete Deck Blocks for Posts

Step 1: Inspect  Your Deck Blocks

Before you begin using concrete deck blocks for posts, it’s important to inspect them thoroughly. Look for any cracks or damage and discard any blocks that are not in good condition. It’s also a good idea to wipe off any excess dirt or debris from the blocks.

Step 2: Plan Your Post Placement

Take some time to plan where your deck posts will be placed. Measure and mark the locations of each post on your deck using a measuring tape, level, and pencil.

Using a shovel or post hole digger, start digging holes at each marked location for your posts. Make sure the holes are deep enough to accommodate the height of your concrete deck blocks plus an extra 6 inches for gravel.

Using a Shovel

Step 3: Add Gravel to Holes

Once your holes are dug, add a layer of gravel at the bottom of each hole. This will help with drainage and prevent your posts from sinking into the ground over time. Carefully place one concrete deck block in each hole on top of the gravel layer. Make sure the blocks are level and adjust if necessary using a level.

Step 4: Set Posts in Blocks

Place each of your deck posts into the holes on top of the concrete blocks. Use a level to ensure they are straight and adjust as needed. Attach metal brackets to the sides of each post using screws or bolts. These brackets will help secure the posts to the concrete blocks and prevent them from wobbling.

Step 5: Add More Gravel

Fill in any gaps around the base of each post with more gravel, making sure it’s compacted and level. Once all your posts are secured in place, use a level one last time to make sure everything is straight and level. Make any necessary adjustments before moving on.

Now that your posts are securely in place, you can begin building your deck. Start by attaching the frame to the posts using screws or bolts. Then, add the decking material of your choice and enjoy your new outdoor space!

By following these step-by-step instructions, you can easily use concrete deck blocks for posts and create a sturdy foundation for your deck. Just remember to inspect your blocks beforehand and take the time to plan and measure before starting the installation process.

What Are Concrete Deck Blocks and How Do They Work?

Concrete deck blocks, also known as concrete pier blocks or foundation piers, are an innovative and versatile type of post support that can be used to create a solid base for a variety of outdoor construction projects. These precast concrete blocks feature a unique design with built-in slots on the top surface and holes through the center, allowing for precise placement and easy installation.

Create a Solid Base

One of the main advantages of using concrete deck blocks is their ability to evenly distribute weight and support heavy loads. This makes them an ideal choice for building a variety of structures, such as decks, sheds, pergolas, and even small cabins. In addition to providing stability and durability, these blocks are also resistant to rot, decay, and insect damage.

How Do You Properly Level and Adjust the Deck Blocks?

Using Concrete Deck Blocks

One of the key steps in using concrete deck blocks for posts is to properly level and adjust them. This ensures that your deck will be stable, secure, and long-lasting. To begin with, it is important to choose a suitable location for your deck blocks. Ideally, they should be placed on firm, level ground that is free from any obstructions or debris. If you are placing your deck blocks on bare ground, it is recommended to first lay down a layer of gravel or crushed stone for added stability.

Once you have chosen the location, place the deck block down and check its level. If necessary, use a shovel or trowel to level out the ground underneath the block. It is important to get this step right as it will affect the stability of your deck. Next, you will need to adjust the height of the deck block.

This is especially important if you are working on uneven ground or have varying lengths for your posts. To adjust the height, simply turn the screw on top of the deck block clockwise to raise it or counterclockwise to lower it. Make sure to check the level again after each adjustment and continue until the block is at the desired height.

Do You Need to Wait for the Concrete to Dry Before Putting Weight on the Posts?

One of the most common concerns when using concrete deck blocks for posts is whether or not you have to wait for the concrete to dry before putting weight on them. The answer is yes, you do need to allow time for the concrete to cure before placing any weight on the posts. Curing is the process in which the concrete hardens and gains strength. This usually takes about 24-48 hours, but can take longer depending on various factors such as temperature and humidity. It is important to follow the manufacturer’s recommended curing time for optimal results.

Once the concrete has cured, you can start placing weight on the posts. This includes attaching beams and joists for your deck or other structures such as pergolas or gazebos. However, it is recommended to wait a little longer before placing heavy loads on the posts, such as furniture or large plants. This will ensure that the concrete has fully hardened and can support the weight without any issues. In addition to waiting for the concrete to cure, it is also important to make sure that you have properly installed the deck blocks.
