Polymer Grouts and Anchors - Under Water Grouts
Product                                                            Description
Non-Sag Epoxy Mortar Binder (633) is a solventless binder suitable for application to overhead, vertical or inclined surfaces. Non-Sag Epoxy Mortar Binder (633) can be applied to damp or wet surfaces. It combines the outstanding properties of General Purpose Epoxy Mortar Binder (133) with a non-sag consistency. Non-Sag Epoxy Mortar Binder (633) may be used for underwater and splash zone repairs including pile restoration.

 Areas of Application
• Bonding new to old concrete on vertical surfaces
• Preparation of thixotropic epoxy mortars for easier vertical and overhead repairs to concrete
• Grouting bolts and anchors in vertical surfaces
• Underwater and splash zone repairs
• Bonding precast concrete units
• Bonding steel and timber to concrete

Sikadur-53 is a pourable high density mortar, based on a 2-component solvent free epoxy resin containing fine fillers. Sikadur-53 is highly insoluble in water and readily displaces water enabling it to be employed in wet and underwater applications.
Uses
Sikadur-53 may be used for underwater grouting work. Excellent adhesion to clean water immersed concrete, stone masonry, brick, wood or steel surfaces. Highly insoluble in water and safe for specialist diver use. Used for injection of cracks 0.5mm to 40mm wide under water (cracks not conducting a water flow under pressure). Ideal for pile jacketing using prepacked aggregate in formwork. Mixed with 30% by volume sand a high build paint is formed that is easy to apply under water.
                                           
Sikadur-53 may be used to grout starter bars and bolts for underwater construction work. The material may also be used as a bonding bridge for underwater concreting and as a pipeline jointing material.
Advantages
  • Applicable in wet, underwater or marine applications.
  • Applicable at low temperatures.
  • High mechanical strengths.
  • Highly insoluble in water and suitable for application by specialist divers.
  • Supplied in factory proportioned units.
  • Shrink free.
  • Excellent chemical resistance to water, sea water, waste water, sewage, fuels, oils, dilute acids and dilute alkalis.
 
Masterflow 1688 UW is a high density high performance epoxy based grouting system designed for structural applications in submerged or water affected conditions. Masterflow 1688 UW is a solvent free, two-component system, with a high flow capability.
Uses
  • Areas requiring grouting below the water level and a moisture insensitive bond to the concrete substrate
  • Structural repair of wharf piles
  • Baseplates and machinery grouting
  • Crane rails and tight clearances
  • Exterior grouting and repair applications
  • Coating structures (e.g. boat ramps) effected by tidal changes during applications
Advantages
  • High early and ultimate strengths
  • High bond strength to steel and concrete correctly prepared
  • Supplied in pre-measured volumes eliminating the need for on site measuring and ensuring product success
  • Easily pumped through suitable equipment
  • Displaces water
  • Excellent chemical resistance against oils, mineral acids, seawater, fuels and alkali solutions
  • Resistance to vibration and high repetitive dynamic loads
  • Solventless – shrink free
Conbextra EP935 is a two component, finely filled, low viscosity, epoxy resin grout. Its high density displaces water to enable high performance underwater suitability. Conbextra EP935 is suitable for underwater grouting work and for the repair of water immersed concrete structures.
Advantages include:
    • Excellent adhesion to water immersed concrete, masonry or brick surfaces
    • High density ensures complete water displacement
    • High compressive, tensile and flexural strengths
    • Cures with negligible shrinkage
    • Pre-measured components allow easy mixing, and free flowing properties ensure speed of application
