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

How OptiSeal Works and Outperforms Traditional Concrete Sealers
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.
Cost-Effective Preservation – Extends pavement life, reducing the need for costly repaving.
Eco-conscious performance – 90% bio-based formulation is carbon-negative, and safer for people and the environment.
