For critical infrastructure projects, a geotechnical engineer will specify the exact strength requirements (e.g., "Grab Tensile Strength must exceed 380 lbs"). Your job is to find a product whose data sheet meets or exceeds those numbers. Do not substitute a lower-spec product to save money, as this could compromise the entire project's safety and design life.
