Antimicrobial Crystalline Technology
Xypex Bio-San – for protection of concrete in severe sewage conditions
Xypex Bio-San is a unique way of protecting concrete in harsh sewage conditions where hydrogen sulphide causes microbial induced corrosion (MIC). No other admixture combines potent antimicrobial properties with Xypex crystalline waterproofing technology to offer protection of concrete sewer and wastewater structures.
Xypex Bio-San contains mineral solids that remain permanently fixed within the concrete throughout the life of the sewage structure. These kill acid-generating microbes such as Thiobacillus that proliferate in H2S conditions thus preventing microbial induced corrosion. Combined with Xypex’s proven crystalline technology, Bio-San will protect concrete from infiltration and exfiltration as well as resisting acid and sulphate attack. After placement and curing, the crack-healing properties of Xypex will continue to function throughout the service life of the concrete.
As with all Xypex Admix products, Bio-San is added at the time of concrete batching, avoiding the potential quality issues of liners or coatings and eliminating schedule delays for surface preparation. As a one-component product, Bio-San simplifies the production process for pre-cast structures.

Xypex Bio-San Technology
Xypex Bio-San is a unique way of protecting concrete in harsh sewage conditions with high levels of hydrogen sulphide that cause microbial induced corrosion. No other admixture combines potent antimicrobial properties with Xypex crystalline waterproofing technology to offer complete protection of concrete sewer and wastewater structures. The animation describes and visually details how Xypex Bio-San addresses and solves Microbial Induced Corrosion (MIC) in sewerage-related concrete infrastructure.
Xypex Bio-San is recommended for use in sewage systems especially in areas where H2S gas is likely to accumulate. This includes sewer lines with long retention times (flat, long, low flow) and sealed or unvented manholes. It will also include areas of high turbulence such as lift stations, drop structures, force main outflows and head works as well as various areas within wastewater treatment plants.

Xypex Bio-San was chosen because it provides the precast sewage elements with protection against microbial induced corrosion and aggressive chemicals, as well as waterproofing and crack healing properties.
