Bullke USA Made Round Foundation Block, 10-Pack
Best for large deck builds and multi-pier projects, this 10-pack delivers consistent footing across several posts. The block is described as durable and strong, designed to withstand outdoor conditions, and is made in the USA from 100% recycled plastic. Its 10-inch diameter and 1 7/8-inch height elevate deck footing more than an inch, improving stability over time. Suitability: ideal for homeowners planning multiple piers or elevated platforms such as decks and floating sheds. Caution: ensure the ground is reasonably level to maximize stability and avoid overloading individual blocks beyond design expectations.
Bullke USA Made Round Foundation Block, 1-Pack
This single-block option mirrors the 10-pack design, offering the same eco-friendly build and elevated footing. It is best for projects that require precise single-pier support, or when supplementing other foundation blocks. Best for mid-sized decks or sheds where a single, sturdy base is needed. Limitation: as a single unit, it may be less economical for larger footprints compared with the 10-pack option.
Handi Block Foundation Block – Deck Support
Best for heavy-load applications like elevated decks and pergolas, this block is described as heavy-duty, UV resistant, and made from 100% recycled plastic. It supports a wide range of joist sizes (1.38-1.61″ and 3.54×3.54″ posts) and is designed to handle up to 1,750 pounds per block with extra safety margins. Choose this if you expect high loads or plan to span larger framing members. Caution: ensure compatibility with your specific post dimensions before ordering.
CAMO Block Heavy Duty Deck Block Foundation (20 Pack)
Best for quick installs on uneven ground, this CAMO block accommodates 4×4 and 6×6 posts, 2×4 to 2×8 wood joists, and even 2-inch metal joists. Its lightweight design (2.16 lbs) yet strong support (up to 1,800 lbs) makes it a strong choice for contractors and DIYers who need repositionable footing after placement. Better for projects needing flexible post sizes and faster setup. Limitation: check that the ground drainage and leveling steps meet the block’s installation requirements for stability.
Bullke Handi Block Original Round Foundation Block (6 Pack)
This 6-pack mirrors the 10-inch diameter and 1 7/8-inch height design, emphasizing eco-friendly production and 100% recycled plastic. It elevates deck footing and provides durable support for floating pier bases and sheds. Best for mid-size deck projects or when consolidating several piers in a compact package. Caution: the per-block load specs should be matched with the overall deck load to avoid overuse.
Buying Guide: Piers For Deck Posts
What to consider before choosing foundation blocks:
- Load capacity: match block capacity to deck size, joist span, and anticipated loads (live and dead loads). Heavier structures benefit from higher-rated blocks.
- Post and joist compatibility: confirm that the block accepts common sizes such as 2×4, 2×6, 4×4 posts, or 4×4 and 6×6 posts, as applicable to your project.
- Ground leveling: uneven ground may require repositionable or self-leveling options to ensure a stable base.
- Material and durability: eco-friendly, recycled-plastic blocks resist weathering and reduce waste; US-made options support local manufacturing.
- Installation approach: consider whether you need a 10-inch diameter base for broader stability or a single-block solution for smaller, targeted support.
- Number of piers: larger decks often benefit from multiple blocks to distribute weight evenly and minimize settlement risk.
- Future projects: if you plan to expand or relocate, blocks with higher adjustability and modularity offer long-term flexibility.
