How Do You Anchor a Deck Block

Deck blocks are typically made of concrete, with a hole in the center for a 4×4 post. To anchor a deck block, dig a hole slightly larger than the block itself and deep enough so that one-third to one-half of the block will be underground. Fill the hole with gravel or crushed stone to help with drainage and then set the block in place.

Use a level to make sure it is level both front to back and side to side, then fill in around the edges of the block with more gravel or crushed stone.

Building a deck is a great way to add value and beauty to your home. But, before you can start enjoying your new outdoor space, you need to anchoring the deck blocks. This may seem like a daunting task, but with a little planning and elbow grease, it can be easily accomplished.

Here are the basic steps for anchoring a deck block: 1. Choose your location: When selecting the location for your deck, make sure to pick an area that is level and has good drainage. You don’t want your deck to be sloped or prone to flooding.

2. Clear the area: Once you’ve selected the perfect spot for your deck, clear away any debris or vegetation that may be in the way. This will give you a clean slate to work with. 3. Dig your holes: Using a post hole digger or auger, dig holes for each of your deck blocks.

The depth of the holes will vary depending on how deep you’re setting the blocks into the ground but should be at least 12 inches deep. 4. Set the blocks: Place each block into its respective hole and backfill with dirt or sand until it’s level with the ground around it.

There are a few different options available, so be sure to choose the one that best suits your needs.

Can Deck Blocks Sit on the Ground?

There are a few different types of deck blocks, but the most common type is made from concrete. These blocks are designed to be placed directly on the ground, without any additional support. The weight of the deck will keep the blocks in place.

There are a few things to keep in mind when using deck blocks though. First, make sure that the ground is level before you start placing the blocks. If there are any low spots, fill them in with dirt or sand so that the blocks will sit evenly.

Second, use a string line or laser level to make sure your rows of blocks are straight. This will give your deck a much cleaner look once it’s finished. Finally, don’t forget to put some gravel beneath each block before you set it in place.

This will help with drainage and prevent pooling water around your deck foundation.

How Do You Set Deck Blocks?

If you’re planning on building a deck, you’ll need to know how to set deck blocks. Deck blocks are an essential part of most decks, providing support for the joists and ledger board. Properly installed deck blocks will keep your deck level and stable for years to come.

To set deck blocks, start by digging holes that are about 1/3 wider than the block itself and about 1 foot deep. Then, place the block in the hole and fill it with concrete, making sure that the block is level with the ground. Once all of your blocks are in place, allow the concrete to cure for 24 hours before proceeding with construction.

When setting deck blocks, be sure to check your local building codes to ensure that you’re following all regulations. With a little bit of planning and effort, you can easily set your own deck blocks and build a beautiful and durable outdoor space.

How Do You Support a Deck With Blocks?

If your deck is more than 2 feet off the ground, you’ll need to support it with posts or columns. The most common way to do this is by using 4×4 treated lumber placed in concrete footings dug below the frost line. For a typical 10×12-foot deck, you’ll need at least four posts.

You can use 6x6s for extra support, but they’re not necessary unless the span of your deck is greater than 16 feet. Before you dig your footings, call 811 to have your utility lines marked for free. Once you know where your footings will go, use a post hole digger or two-person auger to dig each hole to a depth of 30 inches.

Place a 4×4 in each hole and fill the remainder of the hole with concrete mix, tamping it down as you go so there are no air pockets. Let the concrete cure for 24 hours before attaching beams or joists. To attach beams or joists to your posts, use metal post brackets (available at any home center).

To avoid having visible hardware on your deck surface, use hidden fasteners like Simpson Strong-Tie Hidden Deck Fasteners or Ipe Clip Extreme Hidden Deck Fastener System .

How to Use Concrete Deck Blocks for Posts

If you’re looking for a quick and easy way to set your deck posts, concrete deck blocks are the way to go. Here’s how to use them: 1. Choose your location.

Make sure you have a level area that is large enough to accommodate the size of your deck. Also, make sure there are no underground utility lines in the area where you’ll be working. 2. Dig your holes.

The holes should be at least 12 inches deep and slightly wider than the diameter of your deck posts. 3. Set the deck post in the hole and fill with concrete mix according to package directions. Be sure to vibrate the concrete mix well so that there are no air pockets around the post (this will help prevent it from moving later on).

4Repeat steps 2-3 for each of your remaining posts. Let the concrete cure for 24 hours before proceeding to step 5. 5Attach your beams or joists to the tops of the posts using galvanized nails or screws (coated screws will also work but may not last as long).

If you’re using 6×6 posts, you can attach two beams per post using 16d nails or 3/8″ lag bolts placed about 1′ from each end of the beam. For 4×4 posts, only one beam can be attached per post using 8d nails or 3/16″ lag bolts placed about 12″ from each end of the beam . If you’re attaching ledger boards directly to masonry walls, use expansion anchors specifically designed for that purpose . Once all beams are in place, check again for levelness and adjust accordingly .

Fill any gaps between beams with wood shims if necessary . Check connections between beams and posts once more before proceeding . Now is also a good time t o Predrill any holes needed f o r stair stringers , railings , etc., if you haven’t already done so .

This will help ensure that the adhesive has a good surface to grip onto. Next, apply a generous amount of construction adhesive to the top of the concrete deck block. Be sure to spread it evenly so that it can properly adhere to the 4×4.

Finally, carefully place the 4×4 into position and press it firmly against the adhesive. Allow the adhesive to set for at least 24 hours before putting any weight on the 4×4 (such as by attaching furniture or railing).

Can You Bury Concrete Deck Blocks

Are you looking for a way to build a deck without having to spend a lot of money? If so, you may be wondering if you can bury concrete deck blocks. The answer is yes, but there are some things that you need to know first.

Concrete deck blocks are a great option for those who want to build a deck without spending a lot of money. They are easy to install and can be done in a weekend. However, there are some things that you need to know before you start digging.

First, make sure that the area where you will be burying the blocks is level. If it is not, the blocks will not sit evenly and could cause problems down the road. Second, mark out the area where you will be placing the blocks.

This will help ensure that they are all the same depth. Finally, when digging the holes for the blocks, make sure that they are at least two feet deep. This will help ensure that the blocks do not shift over time.

Once you have all of this information, you are ready to start burying your concrete deck blocks! Start by placing one block in each hole and then fill them with dirt or sand until they are level with the ground around them. Once all of your blocks are in place, water them well and allow them to cure for at least 24 hours before using your new deck!

Deck Blocks Vs Concrete Footings

There are a couple of different ways to support your deck. You can use concrete footings or you can use deck blocks. Each option has its own set of pros and cons that you’ll need to consider before making a decision.

Concrete footings are the most common way to support a deck. They’re typically made from poured concrete that’s been reinforced with steel rebar. Concrete footings are very strong and can support a lot of weight.

But, they take longer to install than deck blocks and they require more excavation. Deck blocks are another option for supporting your deck. Deck blocks are usually made from pre-cast concrete or cinder block.

They’re easier to install than concrete footings because there’s no digging involved. And, they’re less expensive too. But, they don’t offer as much support as concrete footings so they might not be suitable for larger decks or decks that will have a lot of traffic on them.


When building a deck, you need to make sure that the deck is anchored securely. One way to do this is by using deck blocks. Deck blocks are usually made of concrete, and they are placed at the corners of the deck.

To secure the deck block, you will need to use some type of fastener, such as a screw or a nail.
