Move over concrete—here come TuffBlocks—the lightest, most versatile and easy-to-use deck foundation system on the market. Tuffblocks allow for an average-sized deck to be constructed from start to finish in under an hour with no digging, steelwork or concreting required. The most daunting part of deck construction—the foundation—is now the fastest and easiest, allowing even the most novice of DIY builders to achieve professional results. Each TuffBlock weighs only 1.5 lbs., yet can support more than 11,000 lbs. The nesting, shipping and packaging of the TuffBlock allows any standard vehicle to carry more than enough TuffBlocks for most jobs. It has been designed to accept 2” x 4”, 2” x 6” and 2” x 8” joists—and 4” x 4” posts—for imperial markets, as well as 35 to 47mm wide joists and 90mm or 100mm posts for metric-based markets. Tuffblocks allow for decks to be built as low as 6.5” without the need for digging—or as high as local codes permit.
