A Disruptive Shift in Building Materials

While technology has transformed nearly every industry, most residential construction materials have remained stagnant.
Traditional gypsum board and OSB, which make up roughly 80% of homes, have seen little innovation in decades.

HydroBlok™ is changing that narrative by eliminating antiquated building materials and introducing a lightweight, waterproof, mold-proof board. This high-performance composite replaces traditional drywall and sheathing materials, offering a modern, efficient alternative that reduces waste and enhances durability.

Proven Efficiency and Cost Savings

Based on early market feedback and internal testing, HydroBlok™ has shown:

• Up to 30% reduction in material and labor costs

• Up to 50% faster build times

• No need for redundant layers or extra insulation — these are built directly into every HydroBlok board

These results demonstrate HydroBlok’s potential to revolutionize construction workflows while delivering superior performance.
