GeoLiner® Geopolymer Mortar

GeoLiner® geopolymer mortar is a fiber reinforced product designed to provide excellent corrosion resistance along with higher strengths and lower permeability than typical cementitious linings. This high performance product can be used for rehabilitation of manholes, wet wells, catch basins, large diameter pipes and tunnels, storm water culverts and WWTP containment structures. Formulated with over 70% pozzolanic content, GeoLiner® can be considered a true Geopolymer.


ADVANTAGES
  • Great adhesion and cohesion
  • Utilizes natural and recycled materials
  • Very low carbon footprint
  • Provides high level of corrosion resistance
  • Restores structural integrity
  • Excellent Bond to damp surfaces
  • Apply up to 3” on vertical surfaces in one coat
  • Spincast or Spray Gun application

APPLICATION
Prepare surface to be patched by removing unsound concrete, dirt, dust, oil and other debris using high pressure (3500 PSI) water blasting. This will provide a clean, damp surface to allow for a good bond. Use approximately 0.5 to 0.6 gallons of potable water per 60 lb. bag of GeoLiner® geopolymer. First add water to mixer, start the mixer and add GeoLiner® geopolymer until mortar is completely mixed, approximately 3 minutes. Apply GeoLiner® geopolymer by low pressure spraying or the spin cast application process on horizontal or vertical surfaces to a monolithic thickness of ½” – 3”.


COVERAGE
Approximately 12 sq. ft. per 60 lb. bag at 1/2 inch thick.
