Protecting concrete in a highly acidic environment can be challenging. The production of hydrogen sulphide that causes microbial induced corrosion in sewage conditions can lead to severe concrete deterioration and a reduced service life of these crucial assets.

Xypex Bio-San C500 is a unique way of protecting concrete in harsh sewage conditions. No other admixture combines potent antimicrobial properties with Xypex crystalline waterproofing technology, to offer complete protection of concrete sewer and wastewater structures. Cement mortar samples containing Xypex were subjected to 5% sulphuric acid for up to 12 weeks. Compared to untreated control samples, the weight loss caused by acid attack was reduced by 48%. In a further test on a 30% fly-ash mortar, the weight loss was reduced to 53%.
