Product Overview

Space Arc Engineering, an Authorized Project Distributor for STP Limited, supplies ShaliGrout® PU 2K 20 — a hydrophobic, solvent and phthalate-free, water-reactive polyurethane reaction system. Upon contact with water, it reacts and expands to form a closed-cell foam, physically blocking water ingress. Used for injection grouting of actively leaking cracks and joints.

Key Applications

• Active water leakage in tunnels and underground structures
• Basement wall and floor crack injection
• Water-leaking joints in dams and water-retaining structures
• Foundation crack injection against pressurized water
• Metro and railway tunnel waterproofing by injection

Advantages

• Hydrophobic — reacts with water to expand and seal
• Solvent-free and phthalate-free — safe for enclosed spaces
• Two-component system for controlled reaction rate
• Closed-cell foam blocks pressurized water ingress
• Suitable for wet and actively leaking surfaces
