Sikadur®-53

Water displacing epoxy resin grout

Sikadur®-53 is a pourable, multi-functional high density epoxy grout based on a 2-component solvent free epoxy resin system containing fine fillers.
Sikadur®-53 exhibits excellent insolubility and displacement characteristics in wet and underwater applications but useable in dry general grouting applications also.

  • Suitable for dry, 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.
  • Can be bulked out with aggregate of thicker pour applications
  • Excellent chemical resistance to water, sea water, waste water, sewage, fuels, oils, dilute acids and dilute alkalis.
  • To be used in conjunction with Sika Pile Jacket systems for rehabilitation of concrete and timber piles in marine applications.

Usage

Sikadur®-53 may be used for underwater and dry grouting work and offers excellent adhesion to both dry and 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 grout is formed that is easy to apply under water.
Sikadur®-53 may be used to grout starter bars, baseplate grouting and bolts for dry and underwater construction work. The material may also be used as a bonding bridge for underwater concreting and as a pipeline jointing material.

Application steps

SUBSTRATE QUALITY

Mortar and concrete must be older than 28 days (depends on minimal requirement of strengths). 

Verify the substrate strength (concrete, masonry, natural stone). 

The substrate surface (all types) must be clean and free from contaminants such as dirt, oil, grease, existing surface treatments and coatings etc. 

Steel substrates must be de-rusted similar to Sa 2.5. (commercial blast)

The substrate must be sound and all loose particles must be removed.

SUBSTRATE PREPARATION

Concrete, mortar, stone, bricks:
Substrates must be sound, clean and free from laitance, ice, grease, oils, old surface treatments or coatings and all loose or friable particles must be removed to achieve a laitance and contaminant free, open textured surface.

 
Steel:
Must be cleaned and prepared thoroughly to an acceptable quality i.e. by blastcleaning and vacuum. Avoid dew point conditions.

 

MIXING

Prior to mixing the components should be stored at 15-20°C for the previous 24 hours. Mix all of component A (Green Resin) with all of component B (Hardener) using a slow speed drill (maximum 600 rpm) and windmill stirrer.
Mix until a homogeneous and streak free mixture results.
If placing underwater allow to stand for 10-15 minutes after mixing before placing.
