WHAT IS POLYURETHANE INJECTION?
Polyurethane injection is a versatile insulation and sealing solution, created by mixing MDI (Isocyanate) and Polyol Blend on-site. It expands to fill gaps, cracks, and cavities, forming a strong moisture and air barrier.
Used in structural reinforcement, waterproofing, and thermal insulation, polyurethane injection enhances durability, reduces energy loss, and improves overall building performance.
TYPES OF POLYURETHANE INJECTION
Polyurethane injection is used for insulation, sealing, and structural reinforcement across various applications.
- HIGH-DENSITY POLYURETHANE INJECTION: Ideal for structural reinforcement and heavy-duty insulation.
Used for concrete lifting, soil stabilization, and industrial insulation. High-density polyurethane injection enhances durability and reduces energy costs.
- MEDIUM-DENSITY POLYURETHANE INJECTION: Used for filling cavities, waterproofing, and reducing air infiltration.
Provides high tensile strength, moisture resistance, and thermal insulation for walls, floors, and ceilings.
- LOW-DENSITY POLYURETHANE INJECTION: Best for lightweight insulation and soundproofing.
Commonly applied for air-sealing, sound dampening, and minor structural reinforcement.
THE MAIN APPLICATION METHODS INCLUDE:
HIGH-PRESSURE INJECTION: Suitable for large-scale projects such as commercial insulation and foundation repair.
LOW-PRESSURE INJECTION: Used for targeted repairs, small cavities, and localized insulation.
POLYURETHANE INJECTION
Polyurethane injection involves injecting liquid polyurethane into cracks, voids, or cavities, where it expands and hardens to create a durable seal or insulation barrier.
