![]() Deck blocks, with their limited anchoring capabilities, become more susceptible to ground shifting. Frost heave: The Upper Midwest region experiences freezing temperatures during winter, leading to frost heave.They can help reduce construction expenses, making them an attractive choice for homeowners on a budget.įrom frost heave to limited load-bearing capacity, there are several disadvantages of deck blocks. Cost-effectiveness: Deck blocks are generally more affordable compared to some alternative foundation options.Accessibility: With deck blocks, the deck surface can be built closer to the ground, making it easily accessible for people with mobility challenges or those who prefer a low-profile deck design.They can accommodate various deck shapes, sizes, and configurations, allowing for flexibility in creating custom deck structures. Versatility: Deck blocks offer versatility in terms of deck design and layout.They are a suitable option for homeowners who want to tackle a deck project themselves or for projects with limited time constraints. Ease of installation: Deck blocks are relatively easy to install, requiring minimal excavation and construction expertise. ![]() The advantages of deck blocks include ease of installation, versatility, accessibility, and cost-effectiveness: While deck blocks seem to be a popular choice, it’s essential to consider the following pros and cons to make a sound decision. Cracks or crumbling in the blocks can compromise the structural integrity of the deck, leading to safety risks and a shortened lifespan for the deck. Over time, exposure to the elements can cause these materials to deteriorate. Lack of Long-term Durabilityĭeck blocks are typically made of molded concrete or composite materials. ShiftingĪs deck blocks are not securely anchored to the ground like alternative foundation options, they can be susceptible to movement, especially in areas with soil that lacks proper compaction or load-bearing capacity. In areas with unstable soil conditions or frost heaves like the Upper Midwest, deck blocks may sink over time, leading to an uneven and potentially unsafe deck surface. ![]() Instabilityĭue to their relatively small footprint and reliance on the ground’s bearing capacity, deck blocks can be prone to instability. Using deck blocks includes potential risks, such as instability, shifting, and a lack of long-term durability. Potential Risks Associated with Using Deck Blocks Let’s address these concerns with some valuable insights to help you make an informed decision for your deck project. However, you may be uncertain about the suitability and reliability of deck blocks as a foundation. Deck blocks have gained some attention as a potentially convenient and cost-effective choice. This sort of structure can still be impacted by soil movement but not the way surface blocks may be.Īs with anything howver it's all down to suitability for different situations.When it comes to building a deck, homeowners have various options to consider, including the type of foundation to use. I’ve included a quick pic of a typical footing head using 90mm post and gal stirrups. is to dig the holes for your footings, build the main framework, raise it up to the right height, get it level, attach the posts & hang them into the holes and then just concrete them all in at once.įor a small deck you’re only going to need around 2 to 3 bags per hole. I’ve found the easiest way to build a deck etc. Lately for anything like this I’ve been using 32MPa rapid-set & it’s awesome. MPa is the rating of compressive strength and most rapid-set products are sub-20MPa.įor structural strength, such as footings, you want at least 24MPa. Pouring basic footings is actually pretty easy especially now that you can get higher MPa rapid-set concrete in bags. You can see this in a house where an extended dry period can cause cracking in walls or in a slab. Soil, especially any soil with even a small amount of clay in it, can be what they describe as reactive – it swells or contracts depending on moisture levels. Personally I see the issue with such options as not to be with their stability but with the soil beneath. I haven't used pre-made concrete foundation blocks or their plastic counterparts myself.
