Stickfoam 1K
Hydrophilic Polyurethane Injection Resin for Sealing Cracks & Leaks
Product Overview:
Stickfoam 1K is a single-component, water-reactive polyurethane injection resin designed to seal water leaks and fill cracks in concrete, reinforced concrete, and brick structures. Upon contact with water, it expands into a flexible, durable closed-cell foam, perfectly suited for applications where substrate movement exceeds 10%.
Key Features & Benefits:
Flexible Water-Activated Foaming
Reacts with water to create a resilient and elastic foam barrier.
Expands to fill hairline cracks and joints, ensuring a complete seal.
Substrate Movement Resistant
Designed for structures experiencing high movement and vibrations.
Maintains flexibility without cracking or breaking the seal.
High Chemical & Thermal Resistance
Withstands wet-dry cycles, freeze-thaw conditions, and exposure to non-polar solvents (e.g., gasoline).
Stable across a wide temperature range (5°C to 30°C).
Simple & Efficient Application
Single-component system for wet crack injection.
For dry cracks, can be mixed 1:1 with water to enhance expansion and elasticity.
Compatible with standard injection systems.
Low viscosity enables deep penetration into fine cracks.
Eco-Friendly & Safe
Non-toxic to humans and environmentally friendly.
No hazardous emissions; safe for indoor and outdoor applications.
Easy to clean equipment with water after use.
Primary Applications:
Sealing leaking cracks and joints in concrete, reinforced concrete, and brick structures.
Waterproofing expansion joints, tunnel segments, diaphragm walls, and concrete panels.
Used in swimming pools, water treatment plants, foundations, wells, and pipe repairs.
Effective in both structural and non-structural crack sealing where water infiltration occurs.
