4/14/2024 0 Comments Concrete deck block![]() Steel framing systems: Steel framing systems provide strength, durability, and resistance to shifting or settling.Professional installation is typically required for helical piles. They offer superior stability, making them suitable for decks in areas with challenging soil conditions. Helical piles: These are steel shafts with helical plates that are screwed into the ground.However, they require more labor and time to install compared to deck blocks. ![]() They distribute the weight of the deck evenly and are a common choice for larger or more complex deck structures. ![]() Concrete footings: Concrete footings provide excellent stability and durability for decks.This can result in sagging or instability, posing safety risks. Limited load-bearing capacity: Deck blocks have a limited load-bearing capacity, and larger decks or structures with heavier loads, such as hot tubs or multiple levels, may exceed their capabilities.This can compromise the structural integrity of the deck and require frequent maintenance or early replacement. Moisture and water damage: Constant exposure to moisture can deteriorate the blocks over time, causing cracks, crumbling, or erosion.In areas with unpredictable soil conditions, such as expansive clay soils, deck blocks may not provide adequate support, leading to an unstable deck structure. Unstable soil conditions: Deck blocks rely on the soil’s bearing capacity for stability.This makes the deck uneven, compromising its stability and potentially causing safety hazards. 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. When it comes to building a deck, homeowners have various options to consider, including the type of foundation to use.
