OptiSeal™ Bio-based Penetrating Concrete Sealant | Pavement Preservation BioSpan Technologies
OptiSeal Penetrating Concrete Seal is the best choice for preserving any concrete surface, both horizontal and vertical. The deep-penetrating solution stops Alkali Silica Reaction (ASR) and seals out moisture. Concrete preserved with OptiSeal is stronger and lasts longer in all climactic conditions.
Application Stage: Post-construction preservation
Purpose: Protects and enhances concrete surfaces

Why OptiSeal is Valuable
Long-Lasting Protection for Concrete Surfaces
Concrete is built to last, but exposure to moisture, chemicals, and daily wear can cause cracking, spalling, and premature deterioration. BioSpan’s OptiSeal Eco-Friendly Penetrating Concrete Sealer offers advanced protection by deeply penetrating the surface, blocking water and contaminants, and extending the lifespan of concrete—all while being biodegradable and safe for people, pets and the planet.

How OptiSeal Works and Outperforms Traditional Concrete Sealers
Unlike conventional sealers that form a surface film, OptiSeal’s penetrating technology ensures that the concrete is protected from the inside out. Once OptiSeal is sprayed onto the concrete surface, it can penetrate up to 4 inches and seals out moisture from the surface down. Green nano-polymers stop ASR and work as a deterrent of rust on embedded rebar. This means:
No peeling or flaking – OptiSeal bonds with concrete for long-term durability, extending the life of concrete in good condition by 7 to 10 years.
Water repellency – Prevents water absorption that leads to cracking and surface damage.
Stain resistance and corrosion protection – Protects against oil, salt, and chemical spills, along with protecting embedded rebar from rust.
Eco-conscious performance – 90% bio-based formulation is carbon-negative, and safer for people and the environment.
