Supershield MULTISEAL

Self-healing Multifunctional Crystalline Waterproofing and Surface Protection for Concrete

MULTISEAL is a high-performance topical crystalline waterproofing and protective treatment powered by Multiseal Crystalline Technology. It combines self-healing, multifunctional SHIELD® Crystals with a hydrophobic molecular barrier, delivering long-lasting protection for both new and existing concrete structures.

When applied to the surface, MULTISEAL penetrates deep into the concrete matrix, where SHIELD Crystals seal pores and microcracks, while the hydrophobic barrier lines capillaries to actively repel water and moisture. This multi-action mechanism provides permanent waterproofing, resistance to chloride ingress, carbonation, chemical attack, and protection against freeze–thaw damage.

By dynamically adapting to environmental changes and enabling autonomous self-healing of microcracks when exposed to water, MULTISEAL ensures superior impermeability, durability, and extended service life, even under aggressive wet–dry cycles and extreme climatic conditions.


Applications

  • Airport runways and parking areas
  • Bridges and highway structures
  • Flyovers
  • Tunnels
  • Multi-story car park decks and structures
  • Seaports
  • Marine structures
  • Buildings
  • Walkways
  • Effluent treatment plants

Features and Benefits

  • MULTISEAL is easy to apply; just spray with a low-pressure sprayer
  • It is water-based, non-toxic, and totally environment-safe. It is certified for use in potable water bodies
  • Provides repellence and multifunctional crystallization
  • Single application and its permanently active
  • Self-healing cracks up to 0.5 mm, and waterproof cracks up to 1.2 mm
  • Provides permanent internal waterproofing and moisture blocking from both positive and negative sources
  • Protects against damage caused by repeated freezing and thawing cycles
  • Provides excellent repelling properties against water, jet fuel, and oil penetration from the surface
  • High resistance against chloride ion penetration and thereby protects reinforcing steel bars against corrosion
  • High chemical resistance
  • Reduces alkali silica reactions, thus eliminating silica dusting
  • Allows concrete to breathe
  • Enhances the adhesion properties of sealants and coatings
  • Prevents concrete scaling and premature cracking on concrete surfaces
  • No appearance changes after the treatment
  • No further protection is required after the treatment like protective plastering
  • Prevents the growth of algae and other vegetation
