Kimberley Wastewater Treatment Plant
The Kimberley Wastewater Treatment Plant project included major new reinforced concrete structures designed to meet demanding hydrostatic, process, durability, and seismic requirements.
The original design included a specification for Xypex surface-applied waterproofing products, while the concrete admixture portion remained open to approved alternatives. After PCL Construction was awarded the project and Salvador Ready Mix was selected as the concrete supplier, Xypex worked with both teams to review the waterproofing requirements and incorporate Xypex Admix C-500 NF into the concrete system. Further, technical review identified area with higher potential for microbial induced corrosion (MIC). Five process structures were reviewed, including two enclosed structures and three open air structures.
Xypex Bio-San was selected for higher risk headspace areas, while Xypex Admix C 500 NF was retained in lower risk areas. This targeted approach allowed Bio-San to be used in areas identified for higher MIC exposure without extending its use throughout the entire project. Xypex also provided onsite technical review, application training, and detailing support for joints, cracks, tie holes, and penetrations.

PRODUCTS USED
Bio-SanA 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 combines potent antimicrobial protection along with the unique crystalline technology of the Xypex Admix C-Series.
Incorporated during batching, add waterproofing and durability to the concrete, with formulations available for a diverse range of mix designs for above-ground and underground structures.
