  • [Multi-format Compatibility] These blocks are designed for installing 3.5 x 3.5-inch wood posts, as well as 1.5-inch wide joists (heights can be 2 inches, 4 inches, and 8 inches). No more wasting time choosing multiple products—simply choose this one solution for both support columns and beams. If you’re seeking a more efficient and cost-effective approach to your construction projects, try our deck blocks today! We’re confident they will exceed your expectations
  • [Strong Load Capacity] Tired of unstable foundations and heavy deck installation? Try our deck blocks! They balance lightness and sturdiness perfectly. Each block weighs only 1.2 lbs—easy to handle like a 500 ml bottle of water—but holds up to 1,700 LBS, offering rock-solid stability with no rocking or tilting. With our tough deck blocks, you won’t have to endure the frustrations of traditional construction methods
  • [Elaborate Design] Many foundation deck blocks on the market suffer from difficult-to-clean crevices and water accumulation issues. Our foundation deck blocks have a central drain that prevents water from pooling and reduces wood erosion, and the deck blocks are designed to be easier to clean, with no sanitary nooks and crannies in the center that cause rainwater to accumulate, and can be cleaned with water or broomed to remove dirt, with lower maintenance costs than concrete supports
  • [Installation Precautions] You may have wondered during your use of the foundation deck block why I can't get my columns to fit when they are clearly 4×4. Don't worry, this is exactly the “little test” that comes with the tight fitting design of the deck blocks! When you have a problem like this, you can gently tap your post or beam with a hammer to make it fit in the deck blocks, which will make the post and the deck blocks fit tightly and maximize stability
  • [Wide Application] Deck blocks are flexible enough to be used in a variety of scenarios, such as decks, sheds, elevated walkways, floating docks, platforms, pools, and a variety of other outdoor scenarios. With the flexibility of “one piece, many uses”, the deck blocks can be used in a variety of different scenarios. Choosing foundation deck blocks is choosing a more efficient, durable and hassle-free outdoor construction solution
