Two Pack Hydrophobic P.U. A & B is a two component, expanding type, solvent free polyurethane liquid chemical grouting material which is injected into cracks and voids to immediately stop water infiltration. The material is fast setting and reacts specifically under wet conditions to expand to several times its original volume.

  SALIENT FEATURES:

• High volume expansion
• Low Viscosity
• Permanently flexible
• Good adhesion to wet and dry surfaces
• Withstands high hydrostatic pressure
• Easy to apply
• Environmentally safe (cured product is inert)
• Impermeable to water
• Bridges wide gaps
• Economical

USES:   Two Pack Hydrophobic P.U. A & B permanently stops water which is infiltrating through:

• Cracked or honey - combed concrete slabs
• Tunnels and dams
• Joints in concrete / rocks
• Canals
• Waste water tanks
• Sewers, manholes and utility boxes
• Pipe intrusions
• Basements
• Voids in pre-fabricated members
