How To Use Concrete Deck Blocks: Easy Process Of Using Concrete Deck Blocks


Concrete deck bricks are rudimentary building pieces that snap together to create structures. They resemble children's toys in appearance. The severe concentrated weights at the bottom of wooden deck posts are meant to be dispersed into sturdy soil by means of these devices. They have several advantages and disadvantages and are only one choice for supporting deck weight. The main limitation of concrete deck blocks is that you should never bury them in the ground because it could lead to rot concerns with the wooden deck supports.

Easy Process Of Using Concrete Deck Blocks

Blocks made of concrete are used to build constructions. They are prefabricated concrete masses with apertures for wood beams on the top. The blocks are often used in situations where it is difficult to mix or transport concrete. The base may be wider than the top, and the top may be different in size or shape. In addition, they are only mechanically attached by friction with the wood deck posts. They might not be allowed in some regions with severe winds because there is frequently no physical connection between the post and the block. Concrete deck blocks should not be used in places with unstable soil since they won't be securely held in place.

Step 1: Select A Feasible Location

Although you may be thrilled with the finished product of your new deck, you must first think about what is below. To assess whether a location is suitable for construction, you must take into account the construction site. Solid and compacted soil are required. You don't want any compression to take place when you're building on the earth. So, when choosing your area, stay away from topsoil. The soil will include a lot of organic debris that is decomposing. Consider the size of the land that your project will require. To determine the size, you may lay out a string line.

Step 2: Choose The Location Of Blocks

Next, choose the location for your blocks. The number of blocks you utilize is up to you. It still relies on your construction, keep that in mind. Place the deck blocks with the right amount of space between them to optimize the deck's strength.

Step 3: Dig Holes & Add Gravel Or Sand

Start by creating holes that are big enough and deep enough to fit your concrete deck pieces. Dig the ground with a shovel. The distance your deck should have from the ground if you choose a floating deck is entirely up to you. Less space will be between the deck blocks on a floating deck that is harder and more resilient.
Use a tamper to compact the area if you observe any loose topsoil that needs to be avoided. Placing concrete deck blocks on gravel or sand is good. The fill allows you to precisely adjust the height of the pier to the desired level while also adding support for the weight of your deck. Furthermore, it won't deteriorate or be affected by seasonal changes. At the bottom of the hole, spread an uniform layer of sand or fine gravel.

Step 4: Place A Landscape Fabric

Landscape cloth prevents grass from growing below. Use landscaping cloth to tarp the area. To keep the fabric in place, use pins. Placing fabric will help stop undesired plant growth while still allowing drainage.

Step 5: Place Your Concrete Deck Blocks & Wood

After the fabric is completely firm up, you may begin prepping the space and laying the concrete deck blocks. Your deck blocks should be placed where they belong. It's essential to level your blocks to prevent structural damage. Level the ground before preparing it for the installation of concrete deck blocks to prevent uneven finished surfaces. If the ground beneath them erodes as a result of unequal weight distribution, the deck blocks can sink. You can add your wood on top of the concrete deck blocks after levelling them.

Pros & Cons Of Using Concrete Deck Blocks

Concrete deck blocks have more drawbacks than advantages. It's crucial to understand that the pier blocks are modest and provide the least amount of support needed for the majority of decks.
Pros
  • Almost always, one person can handle the deck blocks.
  • Concrete isn't mixed on the job site.
  • They are reasonably priced.

Cons
  • There is no mechanical connection between the concrete pier blocks and the wood deck posts. Hope that the concrete lugs on the block don't eventually fall off as the post simply rests on them.
  • The wood deck post must be partially buried since the blocks must be buried, making it vulnerable to moisture intrusion and wood-eating insects. Pictures and accounts of ground-contact treated lumber that has decayed or been attacked by insects are all over the Internet.
  • Steel reinforcement may or may not be present in the blocks. Concrete's strength in tension is just one-tenth that of its strength in compression. Steel reinforcing should be incorporated into all concrete used to support decks.
