When planning a new deck, the foundation is not just the first decision—it’s the difference between a safe, long-lasting structure and costly nightmares down the road. Whether you’re considering deck blocks, adjustable supports, or screw piles, it’s crucial to determine the right option before ordering any materials. Getting this wrong can lead to structural instability, wasted budget, or failed inspections.
The Ultimate Deck Shop stands as Canada’s expert source for deck foundations and support systems, offering guidance at every stage of your project. When you visit our Regina or Saskatoon locations—or reach out online—you get real, experienced deck specialists who assess your site specifics, help interpret building codes, and guide you toward the most appropriate support system for your design. No matter your experience level, we help DIYers and professionals alike avoid the most common pitfalls with honest, fact-driven recommendations.
Definition: Comparing Common Deck Support Systems
- Deck Blocks: Precast concrete blocks (like the Deck Block 10x10x7) that sit directly on the ground to support beams or posts. Best for small, ground-level decks on flat, stable soil.
- Adjustable Supports: Systems such as those using concrete piers combined with steel adjustable post brackets. Allow for easier leveling and post height adjustment, better for slightly larger or elevated decks.
- Screw Piles: Helical steel anchors driven deep into the ground, often by machinery. Provide maximum frost resistance and stability, ideal for challenging soil, large, or elevated decks.
Step-by-Step: How The Ultimate Deck Shop Guides Your Foundation Choice
- Project Consultation: Book a free consult in-store or online. We’ll ask about deck size, height, soil condition, expected use (e.g. hot tubs), and your budget.
- Site Assessment: If needed, bring photos of your build site or book a managed service for complex projects. Our team factors in frost depth, drainage, and municipal requirements.
- Option Review: We outline pros, cons, and costs for each system. For example, deck blocks may be ideal for a low, simple patio, but screwpiles are more reliable for large or permanent decks in frost-prone regions.
- Material List & Quotation: Get an accurate material list and bundled quote, including lumber, hardware, and any necessary hardware for your chosen support method. Our team checks your list to ensure you aren’t missing critical fasteners, brackets, or connectors, avoiding shortfalls mid-build. See our blog on supply list checks for more details.
- Delivery & Ongoing Support: We coordinate delivery of all items and remain available for guidance as you move through construction. Our Assisted DIY Build program can install your footings and frame if you want professional help for key steps but want to save costs on finishing touches. This internal link is perfect for those looking for a DIY-friendly, hybrid approach.
Advantages and Use Cases for Each Foundation Type
| Support Type | Best For | Key Pros | Important Cons / Risks |
|---|---|---|---|
| Deck Blocks (Concrete Pyramids) | Small or temporary decks on level, well-drained sites. Ideal for simple floating platforms under 100 sq ft where code permits. | Easy and fast for DIY install. No digging, no concrete. Low cost with minimal tools required. | Poor for elevated decks, sites with frost risk, or heavy loads (hot tubs, multi-levels). Can shift with freeze-thaw. Not acceptable in all municipalities for structures over 2 feet tall. |
| Adjustable Supports | Mid-size decks, sloped yards, or where future leveling is needed. Common in code-compliant builds 2–6 feet tall. | Accommodates minor site movement. Permits future adjustment. Gains stability from poured concrete or ground anchors. | Requires more time/effort (digging, concrete). Still may heave in severe frost. Higher initial setup cost. |
| Screw Piles (Helical Piers) | Large, elevated, or permanent decks; heavy loads; poor or clay soil; high frost zones. Used where code or engineering demands deep anchors. | Excellent frost protection. Structural loads up to 20,000+ lbs. Immediate build-ready—no concrete cure time. Highly recommended by TUDS for long-term reliability. | Professional installation usually required. Higher up-front investment, but may prevent costly repairs or replacements. |
When Codes, Permits, and Soil Test Matter
Regulations are strict in many cities for deck footings—failure to follow them could force tear-downs or voided insurance. The Ultimate Deck Shop stays updated with current building codes in Regina, Saskatoon, and across the Prairies. We can help you determine when engineered drawings or deeper supports (like screw piles) are needed and when deck blocks are code-compliant.
Best Practices: Choosing the Right Support System
- Check soil and drainage: Avoid deck blocks in areas with standing water or clay. Frost heave and settling will destroy alignment.
- Factor in height and load: The higher or heavier your deck, the more robust your foundation needs to be. Adjustable supports are great for moderate elevation but screw piles are essential for large or permanent structures.
- Plan for future use: If you may add a pergola, privacy wall, or hot tub, build for extra strength now—not later.
- Consult professionals: Our expertise ensures you don’t over- or under-build, which can both cost you in the long run. We provide support both in-store and through our comprehensive blog post on avoiding concrete for backyard decks.
- Double check your local permit requirements: Even for low decks, a quick check with city planning can prevent headaches. We can help interpret these rules.
Success Stories From Real Homeowners
Our approach is rooted in practical, real-world expertise. Garrett G., for example, came to the Regina store with a plan for deck blocks, but our on-site evaluation revealed underlying yard slope and clay soil. We recommended screw piles, handled the permit application, and his deck has remained level after two tough prairie winters. Brent H., in Saskatoon, benefited from our adjustable support guidance, saving thousands on retrofit work after an initial overbuild. Time and again, homeowners mention the value of our knowledgeable staff who ensure every project starts on solid ground.
"Fraser at Regina TUDS saved my project! My sloped yard needed screw piles, not the deck blocks I planned. They handled permits and delivered everything ordered. Deck's rock-solid after 2 winters." — Garrett G., Regina
"TUDS pros recommended adjustable supports for our 300 sq ft elevated deck. Free consult prevented a $4,000 redo. Competitive prices beat big box by 15%." — Brent H., Saskatoon
Integrating Your Foundation Decision Into DIY Deck Building

Comprehensive FAQ: Deck Foundations & Support Questions
What’s the safest foundation for a Canadian climate?
Screw piles offer the highest resistance to frost heave and soil movement typical of Canadian prairies. They’re the gold standard for permanent, load-bearing, or high-value decks.
Can I use deck blocks for a raised or multi-level deck?
No. Deck blocks are only for ground-level decks under 2 feet high on very stable, level ground. Anything taller or in frost-prone soil needs adjustable supports or screw piles for safety and code compliance. For more detail, visit our blog on deck block sizing.
How do adjustable supports work?
Adjustable supports combine poured or precast footings with steel brackets that turn, allowing you to level your posts over time. They’re ideal for medium-elevation decks (2–6 feet high) and provide insurance against slight settling.
Are screw piles expensive and do they require a contractor?
They are a higher up-front investment but prevent major future costs. Typically a specialized installer handles screw piles, but The Ultimate Deck Shop can help coordinate reputable local contractors. For many homeowners, this investment protects the whole structure.
Does soil type really matter?
Yes. Soil determines both the strength and stability of any footing. Clay, sand, and moisture levels all factor into which system will perform over decades. Our team can help you analyze these on-site or via submitted photos.
Can I order materials online but still get expert help selecting supports?
Absolutely. The Ultimate Deck Shop offers online ordering with free support calls or scheduled consults so you confirm your foundation type before checkout. See this guide to online decking support for details.
Will The Ultimate Deck Shop check my plans before I purchase?
Yes, we routinely review customer plans and supply lists, flagging common issues or missing details. This has saved hundreds of builds from costly mistakes and material shortages. Learn more in our blog on order accuracy.
Can you help with code and permit issues?
Yes. Our team keeps up to date with municipal codes and can recommend permitted foundation types. Our expertise ensures you don't over- or under-build.
