The manufacturer has more than doubled in size from its previous 2,500 sq ft facility at the South Humberside Industrial Estate.
Founded less than three years ago, the firm has already won a contract with Google in London, and is currently working directly with Transport for London on a scheme to improve tunnels and platforms on the London Underground.
Fast-Form founder and director Tony White said: “Our new building is a major step forward for the business.
“We are seeing strong growth in the UK but we want to take our products worldwide. We are already in advanced talks with companies in the US.”
Since 2014, Fast-Form has been supported by more than £1m from Finance Yorkshire’s Seedcorn fund.
Finance Yorkshire Investment Manager Graham Davies said: “Fast-Form Systems has proved that its products are a flexible, innovative and energy efficient solution for concrete pours. We look forward to working with Tony as he rolls out his strategy for international growth.”
