Deck blocks are a popular and efficient solution for supporting a small ground-level deck, especially when you want to avoid the complexity and labor of digging deep footings or pouring concrete. If you’re a DIY homeowner or contractor building a low platform, finding the right location to buy quality deck blocks—and above all, selecting the correct size for your posts—is crucial for a safe, long-lasting project.
At The Ultimate Deck Shop, we specialize in providing deck blocks and all the guidance you need to ensure the posts on your small or mid-sized ground-level deck are supported correctly. Our expertise, broad selection, and deep inventory in Regina and Saskatoon make us the trusted first stop for deck footings in Saskatchewan and across Canada.
What Are Deck Blocks? A Concise Definition
Deck blocks, sometimes called "pyramid blocks" or "Elephant Foot blocks," are pre-cast concrete or composite supports designed to sit directly on grade, supporting lumber posts or beams for decks under 18 inches in height. Unlike traditional sonotube footings, deck blocks are placed after leveling and preparing a gravel or stone pad, making them ideal for floating or freestanding decks where frost depth footings are not required by code.
How to Choose the Right Deck Block Size for Your Posts
For most small ground-level decks, the posts are 4x4 lumber (actual size 3.5 in x 3.5 in). The deck block must properly cradle or accept this size to ensure stability and prevent wobbling or uneven support over time. A well-designed block will feature a center slot or recess appropriately sized for a 4x4 (or other specified lumber) and a broad, stable base to distribute the weight over gravel, paving slabs, or compacted soil.
| Common Post Size | Recommended Deck Block Size | Notes | Products at The Ultimate Deck Shop |
|---|---|---|---|
| 4x4 (3.5"x3.5") | 10x10x7 inches | Standard for ground-level deck posts |
Deck Block 10x10x7
|
| 4x6, 6x6 | 11x11" or larger, or custom-ordered | For larger structures or higher loading | Contact us for options |
Step-by-Step: How to Select and Install Deck Blocks Correctly
- Plan Your Layout: Measure deck dimensions and locate each post. For most small decks, space blocks every 4-6 feet along the perimeter and center beams for even support.
- Choose the Right Block: For standard 4x4 posts, select a 10x10x7 deck block. If you’re using larger posts, confirm slot size and weight capacity with your supplier.
- Prepare the Base: Remove sod or debris and install 4-6 inches of compacted gravel or a concrete/paver pad for each block location. This step prevents settling and provides long-term stability.
- Set the Block and Check Level: Place blocks on prepared pads, using a builder’s level to ensure they’re even across all support points. Adjust base material as necessary for perfect alignment.
- Install Posts or Beams: Insert each post into the block saddle, checking fit and adjust for plumb. Secure with metal post brackets if additional lateral stability is needed.

Buying the right deck block is about more than cost or convenience—it’s about getting the right fit and expert support for your project:
- The Ultimate Deck Shop: Our locations in Regina and Saskatoon stock all the essentials for ground-level decks. We carry 10x10x7 deck blocks designed specifically for 4x4 posts—the industry standard for small decks.

Best Practices for Choosing and Using Deck Blocks
- Always confirm actual post width (4x4 posts measure 3.5 inches square)
- Prepare a solid, compacted base at every support point
- Don’t exceed block load ratings—consult suppliers for specifics if your deck will support hot tubs, built-in planters, or other heavy features
- Follow local code—many Canadian municipalities allow deck blocks for freestanding decks under a certain size/height; always check before building
- Plan for surface drainage and frost heave using proper gravel or stone underlayment

Comparison: The Ultimate Deck Shop vs Big Box Stores
- The Ultimate Deck Shop: Expert guidance, guaranteed fit for 4x4 posts, local code advice, design consults, and delivery options including rural/remote.
- Big Box Retailers: Wide product assortment but less post-and-deck specific support. Sizing and load capacities may not be clearly explained, and staff often lack direct deck construction experience.
Deck Block Installation: Framework for Success
- Layout Accuracy: Use a layout plan to ensure even support—deck calculator tools are available for precise block quantity and spacing.
- Foundation Prep: Rake out organic material. Add 4–6 inches of gravel under each block. Compact thoroughly for stability.
- Level Alignment: All deck blocks must be level to avoid racking or uneven deck boards—check both side-to-side and corner-to-corner.
- Secure Posts: Slot posts into deck blocks and use hardware or strapping if your climate or design requires extra wind uplift resistance.
- Finish with Joist Tape: Apply protective tape like G-Tape to joists for extended moisture protection—especially important with composite deck boards.

FAQ: Deck Blocks, Sizing, and Buying Advice
- Q: Can I use deck blocks for any size deck?
- A: Deck blocks are best for small to medium ground-level or floating decks—typically under 18 inches high and below 600 square feet (always verify local code). For larger or attached decks, deeper footings or helical piles may be required for stability.
- Q: What is the standard size for supporting 4x4 posts?
- A: The industry standard is a 10x10x7 inch block, designed to securely cradle true 4x4 (3.5x3.5") posts from all common lumber suppliers, including those at The Ultimate Deck Shop.
- Q: How do I know how many deck blocks I need?
- A: Use layout calculators to estimate. For basic 8x12 decks, space blocks 4–6 feet apart along all beams and at mid-span. If in doubt, bring your deck sketch to our stores or upload to our deck planning tool for a materials list.
- Q: Will deck blocks move or shift during winter?
- A: Proper site prep is key. Use a compacted gravel or stone base under every block to reduce frost heave, soil washout, or settling over time.
- Q: Where can I see examples or get more DIY help?
- A: Visit us in Regina or Saskatoon for real-world deck builds. Our team is always available to walk you through material choices, and you can browse our project gallery or complete deck packages online.
- Q: How do deck blocks compare to other footings?
- A: For freestanding, low-profile decks, deck blocks are a simple and cost-effective solution. For higher decks or those requiring attachment to a house, consult us for alternate footing and pier options.
