The UME Composite System is a design system recommendation for rehabilitating and lining aged lift station structures, or similar (ie- pump and pumping stations, wet wells, etc). The system also provides a proper specification for the execution of lining newly installed structures. The intent of this system is to provide for the waterproofing, sealing, structural enhancement and corrosion protection of existing or newly installed lift stations and similar underground structures by the safe, quick and economical application of a composite created from a uniform and densely compacted epoxy-modified-cementitious layer of design formulated epoxy-modified-mortar combined with 100% solids UME hybrid epoxy – the result is a UME composite lining system.
The recommendations available with this system design establishes the minimum standard for material and methods of application for sealed corrosion protection for existing and newly installed structures. The system is designed in two stages: The high performance epoxy-modified-mortar liner is first applied onto the interior substrate prior to coating. The material will create a high bond strength layer of protection to the repairs and substrate, minimize the occurrence of outgassing, minimize as a barrier to moisture vapor transmission (MVT) and hydrostatic pressure, and be a failsafe as a part of the first layer to seal I&I and chemical attack. The UME composite lining system is then completed with the application of a 100% solids UME hybrid epoxy.
Because of its holistic attributes, the system provides a performance with economics option for all facets of lift station, pumping and pump station lining.
Available in both a hand-applied and spray-applied versions. System is also certified to conform to ANSI/NSF-61 standard for potable, drinking water lining.
