TuffBlock Foundation Calculator
Use this calculator to estimate the number of TuffBlocks required for your deck, shed, or other low-height structure, and get an approximate cost.
Enter the total length of your structure (e.g., deck length).
Enter the total width of your structure (e.g., deck width).
Distance between parallel bearers (main support beams). Typical: 4-6 feet.
Distance between individual TuffBlocks supporting a single bearer. Typical: 4-6 feet.
Enter the estimated cost per TuffBlock.

When planning a new deck, shed, garden room, or any low-height structure, establishing a stable and durable foundation is paramount. Traditional methods often involve digging, pouring concrete footings, or using heavy concrete blocks. However, a modern, efficient alternative has gained significant popularity: TuffBlocks.
What Are TuffBlocks?
TuffBlocks are innovative, lightweight, and high-strength plastic foundation blocks designed to provide a quick and easy footing solution. Made from 100% recycled polypropylene, these blocks are engineered to support substantial weight (typically up to 1,700 lbs or 770 kg per block, depending on the model and ground conditions) without the need for digging or concrete. Their unique design features multiple slots and recesses to accommodate various timber sizes (joists, bearers, posts), offering versatility for different construction needs.
Benefits of Using TuffBlocks
- Ease of Installation: No digging, no concrete mixing, no heavy lifting. TuffBlocks significantly reduce installation time and labor.
- Lightweight: Easy to transport and position, making DIY projects more accessible.
- Durable: Resistant to rot, termites, and moisture, ensuring a long-lasting foundation.
- Versatile: Suitable for decks, sheds, garden rooms, landings, cubby houses, and more. They can accommodate various timber sizes.
- Cost-Effective: Can be more economical than traditional concrete footings, especially when considering labor savings.
- Eco-Friendly: Made from recycled materials.
How to Use the TuffBlock Foundation Calculator
Our TuffBlock Foundation Calculator helps you estimate the number of blocks you'll need for your project. Here's a breakdown of the inputs:
- Structure Length (feet): The overall length of your planned structure.
- Structure Width (feet): The overall width of your planned structure.
- Bearer Spacing (feet): This is the distance between the centerlines of your main support beams (bearers). Bearers typically run parallel to each other. Standard spacing often ranges from 4 to 6 feet, but always refer to your local building codes and timber span tables.
- Block Spacing Along Bearer (feet): This refers to how far apart individual TuffBlocks are placed along a single bearer. Similar to bearer spacing, common recommendations are 4 to 6 feet, depending on the load and timber size.
- TuffBlock Unit Cost ($): Enter the approximate cost of a single TuffBlock from your local supplier to get a total estimated material cost.
Important Considerations for Your Project
- Ground Preparation: While TuffBlocks don't require digging, the ground beneath them should be level, compacted, and well-drained. Consider using gravel or crushed rock for a stable base.
- Load Capacity: Always ensure the combined load of your structure and its contents does not exceed the total capacity of the TuffBlocks used. Distribute weight evenly.
- Local Building Codes: Always check with your local council or building authority. Some jurisdictions may have specific requirements for foundations, even for low-height structures, or may not permit TuffBlocks for certain applications.
- Timber Sizing: The size and type of timber you use for joists and bearers will influence the appropriate spacing for both bearers and TuffBlocks. Consult timber span tables.
- Anchoring: For structures exposed to high winds or seismic activity, consider anchoring options for your TuffBlocks or the structure itself.
By carefully planning and using tools like this calculator, you can ensure a solid and efficient foundation for your next building project with TuffBlocks.
