Xypex Bio-San C500 is a uniquely designed admixture for integral, long-term protection of concrete in harsh sewage conditions with high levels of H2S that cause microbial induced corrosion.

Bio-San C500 combines potent antimicrobial protection along with the unique crystalline technology of the Xypex 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 high 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

Advantages

• Inhibits microbial induced corrosion
• Resists extreme hydrostatic pressure
• Resistant to aggressive chemicals (acids and sulphates)
• Can seal static hairline cracks up to 0.4 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

Dosage Rates

• Xypex Bio-San C500: 1% by weight of total cementitious content.
