Concrete Pier Blocks: The Ultimate Guide to Building Deck & Shed Foundations

Want a new deck for summer barbecues or finally ready to build that shed? A solid foundation is essential. If you’re seeking a cost-effective and manageable solution, concrete pier blocks might be your answer. This comprehensive guide covers everything from choosing the right pier block to troubleshooting common installation issues.

Choosing the Right Pier Block

Concrete pier blocks come in various sizes and shapes, typically square or rectangular, such as 12x8x12 inches and 10-3/4 x 10-3/4 x 7-3/4 inches. Some even include integrated metal brackets or wood caps for simplified post attachment. The right size depends on your structure’s weight – a shed needs more support than a small deck. Always check your local building codes for specific requirements. [https://www.wavesold.com/concrete-curb-machine]

Finding and Pricing Pier Blocks

Home improvement stores like Home Depot and Lowe’s, along with local building supply companies, are your best bet. Expect to pay between $7 and $20 per block, depending on size and features.

Installing Concrete Pier Blocks: A Step-by-Step Guide

Installing pier blocks is a straightforward process:

Planning: Determine the number of blocks needed based on your structure’s weight and local building codes.
Site Preparation: For each block, level the ground and create a compacted gravel base for drainage and stability. This helps prevent shifting over time.
Block Placement: Carefully set each block on the gravel, ensuring it’s level and correctly spaced using a level. Double-checking now saves headaches later!
Securing the Structure: Attach posts or beams using appropriate hardware like brackets or anchors for a rock-solid connection. [https://www.wavesold.com/construction-screws]

Troubleshooting Common Issues

Even with careful planning, issues can arise:

Wobbly Posts: Check if the block is level and firmly on the gravel. Ensure the hardware connecting the post is secure and properly installed.
Uneven Ground: If the ground settles, excavate under the affected block, re-level, and add more gravel for a stable base.

Comparing Foundation Options

How do concrete pier blocks compare to other foundations?

Feature	Concrete Pier Blocks	Poured Concrete Footings	Helical Piers	CAMO BLOCK
Cost	Low	High	Moderate	Moderate
Installation	Easy	Difficult	Moderate	Easy
Load Capacity	Moderate	High	High	Moderate
Longevity	High	High	High	High

This table offers a general comparison. The ideal choice depends on your project’s specific requirements.

Exploring New Materials

Building materials are constantly evolving. CAMO BLOCK, a newer option, is often lighter and made with sustainable components. Research its load-bearing capacity and suitability for your project. Some experts believe that while newer materials offer potential advantages, long-term performance data is still being gathered.

Building Codes: Essential for Compliance

Always check your local building codes before starting. Regulations vary, and compliance ensures your structure is safe and meets all requirements.

Are Concrete Pier Blocks Right for You?

Concrete pier blocks provide a practical, cost-effective, and relatively simple foundation solution for decks, sheds, and other outdoor structures. Proper planning, installation, and adherence to building codes are crucial for success. Choose the correct size blocks for the load, prepare the site thoroughly, and prioritize safety. Ongoing research suggests that regular inspection of pier blocks can prevent potential long-term issues.

Concrete Walls: Poured vs. Block – A Cost Comparison

Choosing between poured concrete and concrete blocks for a wall depends on various factors, making a simple cost comparison complex.

Material Costs

Concrete might seem cheaper initially, but concrete blocks (CMUs) come in various types and prices.

Labor Costs

Poured concrete typically requires skilled professionals, increasing expenses. Block walls are often more DIY-friendly, potentially saving on labor.

Equipment Costs

Poured concrete often involves costly equipment rentals. Block construction typically uses more basic, less expensive tools.

Hidden Costs

Consider additional expenses like rebar, formwork, mortar, grout, and wall ties.

Long-Term Costs

Concrete walls generally require less maintenance than block walls. Insulation plays a critical role in long-term energy efficiency for both.

Choosing the Right Wall Type

There’s no definitive “cheaper” option. The best choice depends on project specifics, DIY skills, and long-term goals.

Comparing Poured Concrete and Concrete Block Walls

Feature	Poured Concrete	Concrete Block
Initial Material Cost	Moderate to High	Low to Moderate
Labor Cost	High	Moderate to High
Installation Time	Relatively Quick (initial pour)	Longer
Durability	Excellent	Very Good
Maintenance	Low	Moderate
Design Flexibility	Less Flexible generally	More Flexible generally
DIY Suitability	Lower	Higher

Innovations in Wall Construction

Explore newer technologies like Insulated Concrete Forms (ICFs) and CAMO BLOCK, which may offer cost and energy efficiency advantages.

Building Codes Matter

Always consult local building codes before starting any wall project for compliance and safety. There is debate about the long-term cost-effectiveness of some newer wall systems, and further research may provide more conclusive data.

Rebar in Concrete Piers: When and How

Rebar reinforces concrete piers, providing tensile strength to resist stretching and bending. Whether you need it depends on several factors:

Load: Larger loads, like a two-story deck, likely require rebar.
Soil Conditions: Unstable soil, prone to shifting or frost heave, often benefits from reinforced piers.
Pier Height: Taller piers are more susceptible to bending, making rebar often necessary.
Seismic Activity: In earthquake-prone areas, rebar is crucial.
Building Codes: Local codes are your ultimate guide and should always be consulted.

Installing Rebar

Vertical Placement: Use evenly spaced vertical rebar rods (#4 or #5 are common) within the pier form.
Concrete Coverage: Ensure at least two inches of concrete surrounds the rebar to prevent corrosion.
Horizontal Ties: Smaller rebar pieces wrapped around vertical rods provide extra support, especially for larger piers.
Footing Connection: Extend vertical rebar into the footing for a secure connection if applicable.

Alternatives to Rebar

Fiber-reinforced concrete can sometimes replace traditional rebar, but consult building codes and potentially a structural engineer.

Choosing whether to use rebar is crucial. Understanding load, soil, pier height, seismic activity, and local codes helps make the right decision. While current knowledge strongly suggests the importance of rebar in specific situations, research into alternative reinforcement methods is ongoing.
