For protection of concrete in severe sewage conditions.
Xypex Bio-San C500 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 C500 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 C500 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 C500 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 C500 simplifies the production process for pre-cast structures.
Xypex Bio-San C500 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 Megamix II with Bio-San is a resurfacing mortar specifically designed for the restoration of deteriorated concrete surfaces caused by microbial induced corrosion, abrasion/erosion and chemical attack. It is formulated for ease of application, superior bond, low shrinkage, high strength and
resistance to microbial, acid and sulphate attack. Xypex Megamix II with Bio-San is a one component
mortar and can be spray or trowel applied at a thickness of 10 - 50 mm per layer. The high performance
characteristics of Megamix II with Bio-San are enhanced by Xypex’s unique crystalline waterproofing and protection technology. In most applications, such as manhole resurfacing, Megamix II with Bio-San can be used to replace epoxy linings and calcium aluminate repair mortars. Learn More about Megamix II with Bio-San
