Best Concrete Deck Footing Blocks and Alternatives for Deck Projects
For a deck footing, choose a support that matches the structure, ground conditions, framing, and local building requirements. The products listed here are recycled-plastic foundation blocks and adjustable pedestals, not concrete blocks. The Bullke Handi Block is best for standard joists or 4×4 posts; its round version is suited to a compact, low-profile support. MCCKLE’s adjustable pedestals are better for projects that need height adjustment, with the 10-pack for smaller layouts and the 24-pack for more supports.
| Product | Best suited for | Key listed feature |
|---|---|---|
| Bullke Round Foundation Block | Low-profile support | 10-inch diameter; 1 7/8-inch height |
| MCCKLE 10-Pack Adjustable Pedestals | Smaller adjustable layouts | Height adjusts from 2 3/8 to 5 1/2 inches |
| Bullke Foundation Block | Joist or 4×4 post support | Accepts listed joist and post sizes |
| MCCKLE 24-Pack Adjustable Pedestals | Larger adjustable layouts | Same height range as 10-pack |
Bullke Round Foundation Block
This round support is best for buyers who want a low-profile pedestal for a deck, shed, or pier-and-beam project. The listed dimensions are 10 inches in diameter and 1 7/8 inches tall, with the design lifting the supported structure more than an inch above the ground. The product description states a 1,250-pound support capacity.
It is made in the USA from 100% recycled plastic and is described as recyclable. Choose it if a round footprint and modest elevation suit the plan. Its low height does not provide the adjustment range of a screw-style pedestal, and the listed information does not specify compatibility with particular joist or post sizes.
MCCKLE 10-Pack Adjustable Pedestals
This 10-pack is best for smaller projects or layouts that require variable support height. Its polypropylene pedestal uses a screw ring to adjust from 2 3/8 inches to 5 1/2 inches. The listed features also describe ventilation intended to limit water buildup and a design that raises boards above the ground to encourage drainage.
The manufacturer lists support capacity of 4,600 pounds at the lowest setting and 2,000 pounds at maximum height for each pedestal. Those figures are product claims; confirm suitability for the actual design and installation conditions. Choose this pack if adjustability matters more than a fixed foundation block. Avoid assuming that the stated capacity alone establishes code compliance or replaces structural planning.
Bullke Standard Foundation Block
This Bullke block is best for buyers who need a support shaped to accept common framing members. The listed fit includes joists measuring 1.38 to 1.61 inches and 3.54-inch-square posts, described as standard 2x lumber and 4×4 posts. The product description gives a 1,750-pound capacity per block and says it was tested above 15,000 pounds.
Its listed applications include decks, sheds, pathways, raised walkways, pergolas, and gazebos. It is presented as an option that avoids digging, but that does not mean it is suitable for every site or deck. Choose it when the framing dimensions match and a fixed support works for the design. The product details do not provide an adjustable height range.
MCCKLE 24-Pack Adjustable Pedestals
This 24-pack is best for larger layouts that need multiple adjustable supports. Like the 10-pack, these polypropylene pedestals adjust from 2 3/8 to 5 1/2 inches with a screw ring. The listed features include ventilation, resistance to corrosion, oxidation, and UV radiation, and support capacities of 4,600 pounds at the lowest position and 2,000 pounds at maximum height per pedestal.
Choose the larger pack if the planned support layout calls for more units; it has the same stated adjustment range and per-pedestal capacity as the smaller pack. The product information does not establish how many supports a particular deck needs. Avoid selecting a quantity or spacing based only on pack size—follow the deck design and applicable requirements.
Buying Guide: How To Choose Deck Footing Blocks
Do you need concrete or a plastic pedestal?
These listed products are plastic supports, not concrete footing blocks. A plastic block or pedestal may suit a project designed for surface supports, while another site or structure may require concrete footings or a different foundation system. Soil, drainage, frost conditions, deck height, and local building rules can affect what is appropriate. Check local requirements before buying materials.
Should you choose fixed or adjustable height?
Fixed blocks offer a set support height and may have shaped channels for joists or posts. Adjustable pedestals provide a stated range of 2 3/8 to 5 1/2 inches, which can help accommodate planned height differences and improve separation from the ground. Confirm the required finished height and framing fit before choosing.
How should you compare load capacity?
Compare the stated capacity at the height and configuration you intend to use. MCCKLE lists different capacities at minimum and maximum height. Bullke also provides product-specific capacity claims. Do not treat a single block’s stated capacity as the safe capacity of a complete deck: support spacing, connections, ground stability, and the structure’s total loads matter.
What should you check before installation?
- Confirm the support fits the actual joist or post dimensions.
- Check whether the site needs excavation, drainage work, or frost-depth footings.
- Plan support placement using the deck’s structural design rather than pack quantity alone.
- Review local building codes and obtain professional guidance when the requirements are unclear.
Frequently Asked Questions
Are these products concrete deck footing blocks?
No. The products described are recycled-plastic blocks or polypropylene adjustable pedestals. They are alternatives to consider only when appropriate for the project and local requirements.
Which option has adjustable height?
Both MCCKLE packs adjust from 2 3/8 to 5 1/2 inches using a screw ring.
Which block lists compatibility with 4×4 posts?
The Bullke Standard Foundation Block lists compatibility with 3.54-inch-square posts, identified in its description as 4×4 posts.
Does a higher stated load capacity mean fewer blocks are needed?
Not necessarily. The number and spacing of supports depend on the complete deck design, loads, connections, and ground conditions—not a block’s capacity in isolation.
