Episode Details

This episode dives into Tier 4 hardware — the stuff where failure means property damage, serious injury, or building code violations. We break down structural concrete anchors, chemical anchoring, fire-rated fixings, and structural timber connectors with an Israel-specific focus on reinforced concrete, hollow block (ITONG/thermostone), and post-tensioning cables. Learn which anchors lose 40% holding power in cracked concrete, why generic resin cartridges are a gamble, and how a single misplaced drill bit into a post-tensioning cable can compromise an entire slab. Plus: the real difference between grade 8.8, 10.9, and 12.9 bolts, and why higher isn't always better.
