Yes - TuffBlock Pro supports both timber and steel systems.

Yes. TuffBlock Pro is designed as a floating foundation system that can help accommodate minor seasonal movement caused by freeze-thaw cycles and frost heave. Unlike rigid in-ground concrete footings, floating foundation systems can move more naturally with changing ground conditions when installed on a properly prepared and compacted base. Proper drainage and local code requirements should always be followed.

TuffBlock Pro is engineered to distribute loads evenly across stable, compact ground surfaces. This floating foundation approach can help reduce stress caused by minor soil movement, seasonal expansion, contraction and settling compared to rigid footing systems. Long-term performance still depends on proper site preparation and drainage management.

When installed on a properly prepared and compacted base, TuffBlock Pro is designed to distribute load evenly and provide stable support for outdoor structures. Unstable soil, poor drainage or inadequate site preparation can affect the performance of any foundation system, including traditional concrete footings.

Deck permit requirements vary by city and county, and most residential decks must meet local building code requirements.In many areas, you will need a building permit for a deck if it:

-Is attached to your home and is more than 40" above grade.
-Exceeds a certain square footage.
-Includes stairs, railings, or a roof structure.

Some jurisdictions provide deck permit exemptions for small, freestanding or low-profile decks under a certain size. However, permit rules differ depending on your local building department. Because deck permit requirements vary nationwide, always contact your local building department before starting your project to confirm permit and inspection requirements.
