No Digging. No Concrete. Build yours This Weekend.
How to Build an Instant Floating Deck
Install in 3 Simple Steps
1Prepare Your Base
Prepare the ground by removing loose topsoil or vegetation. Compact the ground with a tamp, and consider using aggregate like crushed rock or paver base.
2Place & Level TuffBlocks
Position TuffBlocks directly on your prepared surface and adjust each point to create a level foundation. Their wide base and smart design distribute load evenly.
3Build Your Frame & Deck
Install your joists or posts directly into the TuffBlock slots and begin building immediately. For added stability in high-wind or elevated builds, TuffBlock can be paired with earth anchors or hybrid footing systems.

How to Build Easy With TuffBlocks
Drop
Place your TuffBlocks directly onto firm, level ground — grass, dirt, gravel, or even concrete. No need to dig holes or pour footings. Just space them where your posts or joists will go.
Level
Use a spirit level to make minor ground adjustments if needed. TuffBlocks work best on flat, stable surfaces — and minimal prep is all it takes. Tip: Use packers such as crusher dust underneath for extra stability and longevity.
Build
Drop in your 3.5" or 4" posts or 1½" - 2" Joists & Bearers — From here, just start building your deck, shed base, stairs, or even tiny home floor.
