How to select the right injection materials?

Polyurethane

Good performance with water

  • 1&2 component
  • Solvent free
  • Flexible to rigid
  • Strength : 2 – 50 N/mm2
  • Adhere extremely well to wet substrate
  • Retains shape on drying & wetting
  • Non corrosive

Epoxy

Bad performance with water

  • 2 component
  • Solvent free
  • Very rigid/hard
  • Strength : 70 – 100N/mm2
  • Poor adhesion

Cementitious

Good performance with water

  • Man made mineral based binder
  • 3 component (Powder, Water, Admixture)
  • Rigid/hard
  • Strength : 40 – 50 N/mm2

Acrylates

Good performance with water

  • Excellent adhesion for 
 movement structure
  • 4 component  
 (A1 + A2 + A3 , B , Water)
  • Very soft and flexible
  • Strength : negligible
  • On drying shrinks does not return to original shape
  • Corrosive
