How Do You Use Concrete Deck Blocks?
Concrete deck blocks are pieces used to create structures. They are prefabricated concrete masses with openings in the top that can accommodate wood beams.
The blocks are typically utilized where mixing or transporting concrete is challenging. The top and base differ in size or shape, as the base can be wider than the top.
They also have no mechanical means of attachment other than friction with the wood deck posts. Since there is often no physical connection between the post and the block, they might not be permitted in some areas with strong winds.
It is also not advisable to use concrete deck blocks in areas where the soil is unstable and won't firmly keep the deck block in place.
If you want to construct something out of concrete deck blocks, here's how you should use them:
1. Select a Feasible Location
You might be excited about the result of your new deck, but first, you need to consider what goes below. You must consider the construction site to determine whether building in that place is possible. The soil must be solid and compacted.
When you build on the soil, you don't want any compression to occur. So, avoid topsoil when selecting your location. There will be a lot of decaying organic matter in the soil.
Think about the land area that your project will cover. You could put down a string line to get an idea of the dimensions.
2. Choose the Location of Blocks
Next, determine where your blocks will go. It depends on you how many blocks you will use. Remember that it still depends on your construction. To maximize the deck's strength, place the deck blocks with the appropriate amount of space between them.
3. Dig Holes
You can start to dig holes that are wide and deep enough to place your concrete deck blocks. Use a shovel to dig the soil.
If you want a floating deck, it is up to you how much gap you want your deck from the soil. A floating deck that is firmer and more durable will have less space between the deck blocks.
If you see any loose topsoil to avoid, compact the areas with a tamper.

4. Add Gravel or Sand
The ideal concrete deck block placement is on gravel or sand. The fill will add support to the weight of your deck and also lets you modify the height of the pier to exactly where you want it to be.
Additionally, it will not erode or be impacted by seasonal fluctuations. Spread an even layer of sand or fine gravel at the bottom of the hole.
5. Place a Landscape Fabric
Grass will not be able to grow below due to landscape fabric. Cover the area with landscape fabric. Place pins to hold the fabric in place. Placing fabric will still permit drainage while assisting in preventing unwanted plant growth.

6. Place Your Concrete Deck Blocks
Once you have finished setting up the fabric, you can start preparing the area and placing the concrete deck blocks. Place your deck blocks in their designated places. Leveling your blocks is crucial so that no structural damage will happen.
To prevent uneven finished surfaces, level the ground before preparing it for the installation of concrete deck blocks. The deck blocks could sink if the earth beneath them erodes due to uneven weight distribution.
7. Place the wood
After leveling your concrete deck blocks, you can place your wood on top.
How Far Apart Should Concrete Deck Blocks Be?
Remember that the distance between blocks depends on what you will construct and the soil type. It will also determine how many blocks are required for a deck foundation.
The maximum space between the center of two concrete deck blocks must be 5 feet. Make sure the blocks are equally spaced apart by measuring them with a tape measure.

Advantages Of Using Concrete Deck Blocks
Concrete deck blocks are commonly used among DIY homeowners. Below are the advantages of using concrete deck blocks:
Supports Elevated Decks
You can create floating decks using a variety of deck blocks. Make sure to distribute the concrete deck blocks evenly to have a strong foundation.
These concrete deck blocks offer a strong and stable base for your upper deck. They make ideal small-to-medium-sized decks because of their significant load-bearing capacity.
There is no concrete mixing required on site. These concrete deck blocks resemble ready-to-use building supplies you can use right out of the package. You can also easily find them in your neighborhood hardware store.
Simple to Install
Setting it up is simple because you will not need construction tools; you will just lay the concrete deck blocks down. These blocks require only surface preparation and digging. It also requires you to do some basic carpentry skills to install the deck.
Concrete deck blocks are best for decks since they are corrosion-resistant and do not quickly degrade.
Plenty of Sizes
Concrete deck blocks come in a variety of sizes and forms. You may choose the size you think is the best for your project.
Concrete deck blocks are a popular choice among builders since they are a cheap way to support decks. Utilizing this type of block can reduce the overall cost of the project.
How Much Do Concrete Deck Blocks Cost?
The average price of a concrete deck block is usually inexpensive and ranges from $4 to $6. Remember that it still depends on the size of the concrete deck block and also on the supplier.
There will be an additional labor charge if you want the supplier to deliver the blocks to you and for installation.
What Is The Size Of A Concrete Deck Block?
Concrete deck blocks come in different sizes depending on your supplier. It is crucial to know the appropriate size for your project so that you will also know the actions to take during construction. Typically, blocks range from 10-11 inches at the base and 7-8 inches tall.
What Is The Weight Of A Concrete Deck Block?
The deck block typically weighs 48 pounds.
How Much Weight Can Concrete Deck Blocks Support?
You must consider the weight of the deck your concrete blocks will support. The standard weight that a concrete deck block supports is 1,700 pounds.
The weight of your deck and the weight each deck block can support will determine how many decks blocks you need.
Building a deck foundation can be done quickly and easily using deck blocks. Make sure to apply either sand or gravel underneath your concrete deck block, for appropriate drainage and support. Also, remember to level them all equally for sturdiness and to prevent your deck from getting damaged.
Always remember that a well-thought-out foundation for your deck will result in an excellent finish. Before you leave, make sure to check out these other exciting posts of ours:
