Do you want to build a new deck or replace an old foundation? If you choose the right deck support blocks, your outdoor structure will stay level, stable, and safe for many years. VEVOR offers deck support blocks designed to suit various ground conditions, load requirements, and construction methods. Our foundation solutions give your project the structural integrity it needs. They work for everything from simple backyard decks to complex multi-tier installations.
When choosing deck support blocks, it's important to know how much weight they need to hold and how tall they need to be. Depending on their size, intended use, and local weather conditions, outdoor structures require different levels of support.
Support blocks for decks must be able to handle both dead loads (such as the building itself) and live loads (such as people, furniture, and tools). For ground-level decks with simple framing, standard plastic deck support blocks can hold up to 2,000 pounds each. Lighter buildings or business uses can use heavy-duty deck support blocks that can hold 3,000 to 5,000 pounds per support point.
To figure out what you need, you should look at the deck's overall square footage, the distance between the joists, and how you plan to use it. For a simple 10x10-foot deck at grade, you might only need about 9–12 basic blocks. But for a bigger deck with stairs and railings, you'll need carefully placed supports with higher load ratings. Always check your local building codes, as many areas require engineered footings for decks over a certain size or height. VEVOR's range offers options for both home and business use, so you can be sure to find blocks that meet or exceed your load standards.
Variations in ground level are one of the biggest challenges when building a deck. Because they typically adjust from about 1 in to 24 in or more, adjustable deck pedestals solve this problem. They let builders make perfectly level surfaces on uneven ground. The threaded posts or stacked parts on these pedestals let you fine-tune the height with outstanding accuracy.
Modestly sloped yards may not require extensive digging or complex concrete footings when you use adjustable pedestal systems. You can set each support to the exact height you need, accounting for grade changes while keeping the joists at the same level. This flexibility significantly reduces building time and labor costs. Flexible plastic deck supports are ideal for relatively flat surfaces that require little to no height adjustment. VEVOR offers both fixed height and adjustable deck support blocks, so you can choose the ones that work best for your site without sacrificing stability or going over budget.
Different deck shapes require different foundation methods. Basic plastic deck blocks placed on compacted soil bases work well for ground-level decks that are typically less than 12 in high. These low-profile solutions provide reliable support for everyday residential use while keeping installation simple and cost-effective.
For installations on rooftops, raised decks, and around pools, you need stronger options. In these situations, adjustable deck pedestals work excellently, especially when building on concrete, roof membranes, or uneven hardscape, where traditional concrete footings may not be practical. Choose blocks rated for vertical load and wind resistance for shade structures like pergolas and gazebos to prevent movement during storms. You can use reusable plastic deck supports that don't need concrete to build temporary or seasonal decks. This design makes it easy to take apart and move the supports as needed.
The proper spacing between deck support blocks directly affects how well the structure performs and how long it lasts. Most building codes require a support post every 4 to 8 feet, depending on the size and type of the joists. A typical block spacing for 2x8 joists is 6 feet, while a suitable block spacing for 2x10 or 2x12 joists can allow them to span slightly longer lengths.
Cantilevers and edge loads put extra stress on corner and exterior supports, which is why they often need to be closer together and/or use higher-capacity blocks. When planning your layout, create a grid that aligns with the joist runs and maintains even spacing throughout. For deck footing blocks that support beam systems, put them right under where two beams meet and at regular places along the runs of the beams. The technical specs for VEVOR help you determine how many supports you need and where to place them so your deck meets building codes and lasts a long time.
If you choose deck support blocks made of the right materials and know how to place them correctly, your foundation system will work reliably through all four seasons and all kinds of weather. VEVOR uses long-lasting materials and easy-to-assemble designs, so both professional builders and do-it-yourselfers can use them. Traditional wood blocking doesn't hold up as well against water, rot, and ground contact wear and tear as high-density polyethylene and reinforced composite materials. When these materials freeze and thaw, they don't crack or degrade; instead, they retain their structural properties. There are different ways to install them, from simple surface placement on compacted bases to more permanent options like concrete or buried footings. This method gives you options based on local rules and site needs.
VEVOR makes a full line of deck foundation blocks that work just as well as professional-grade deck support blocks but are more affordable. Our heavy-duty footing systems, adjustable deck pedestals, and plastic deck blocks are all reliable ways to support decks in residential and light commercial settings. VEVOR makes professional deck building possible for both contractors and individuals by providing easy-to-follow installation instructions, detailed product descriptions, and helpful customer service.
