Ultra CRM™ Chemical Resistant Membrane

Ultra CRM™ is a strong, 60-mil, post-applied  membrane designed and tested to withstand elevated concentrations of soil, fluid and vapor contaminants when installed on below grade concrete or CMU structures; such as concrete foundation walls, tunnels, parking garages and related applications where chemical resistant waterproofing is critical.

FEATURES & BENEFITS

  • Superior Barrier: Provides a barrier that has been designed and tested to withstand elevated concentrations of contaminants typically found in construction sites which may be considered brownfield projects.
  • Quality Composite: Proprietary adhesive compound bonded to a Chemical Resistant Membrane ensures uniform thickness and performance.
  • Precision: Factory controlled side seams combined with CR™ Seam Tape ensures monolithic application with enhanced seam integrity.
  • Fully Adhered: Enhancing the durability of the membrane and mitigating lateral water migration.
