Bio-San C500

Xypex Bio-San C500 is a uniquely designed admixture for integral, long-term protection of concrete in harsh sewage conditions with levels of H2S that cause microbial induced corrosion (MIC). Bio-San C500 combines potent antimicrobial protection along with the unique crystalline technology of the Xypex Admix C-Series.

Bio-San contains bio-active mineral solids that become permanently fixed within the cement matrix impairing bio-film formation thus inhibiting the growth of acid causing sewer bacteria such as Thiobacillus due to concentrations of H2S. The unique Xypex Crystalline Technology creates a permanent structure throughout the pores and capillary tracts providing waterproofing and enhanced chemical protection including acid and sulphate resistance. Bio-San C500 prevents microbial induced corrosion, stops infiltration/exfiltration of water, and provides acid and sulphate resistance, significantly extending the service life of concrete sewage collection systems and waste water infrastructure.

Recommended for:

  • Manholes / Sewer Pipes
  • Pump and Lift Stations
  • Head Works
  • Septic Tanks
  • Digesters
  • Clarifiers
  • Industrial Structures


  • Inhibits microbial induced corrosion
  • Resists extreme hydrostatic pressure
  • Resistant to aggressive chemicals (acids and sulphates)
  • Can seal static hairline cracks up to 0.5 mm
  • Becomes a permanent, integral part of the substrate and cannot be punctured, damaged or lose adhesion
  • Does not contain any VOCs
  • Less costly to apply than most other methods
  • Added to the concrete at the time of batching and therefore not subject to weather and surface moisture constraints
