They aren't designed to supply much lateral support. They're meant to support a deck post. **Q: My local building inspection office requires an icc, intertech, or similar evaluation product evaluation for new products does this have one?** A: Yes, their website shows the product has been evaluated and been certified. Search Tuff Block certification and the search should take you to the web page with the information! Good Luck! **Q: How many would i need for a 20'x20' woodworking shop/ shed with a loft?** A: One big package does 10x10 so I would get 2. I had maybe 5 blocks left over. ## Frequently Bought Together - TuffBlock - Instant Foundation Block for Decks (24-Pack) - Pro-Grade Composite Shims for Heavy Duty Leveling. 24 pk 7.75 Inch, Never Rot, Easy Snap, Level Wedges.
