07 Assessment

Advantages

  • Permanent waterproofing solution - lifetime of concrete
  • Self-healing capability for cracks up to 0.4mm
  • Resists extreme hydrostatic pressure (positive/negative)
  • Becomes integral part of concrete structure
  • NSF 61 approved for potable water contact
  • Breathable - allows vapour transmission
  • Chemical resistant to pH 3-11
  • No surface preparation for negative side application
  • Increases concrete durability and lifespan
  • Non-toxic and environmentally safe

Constraints

  • Requires saturated surface dry (SSD) substrate
  • Cannot bridge structural cracks >0.4mm
  • Minimum 7-day concrete cure before application
  • Temperature sensitive during application (5-35°C)
  • Requires protection from rain for 24-48 hours
  • Professional application recommended
  • Not suitable for non-cementitious substrates
  • May show efflorescence initially
  • Requires CSP-4 surface profile for optimal performance
