The surface preparation for steel and concrete is different from one another surface types as it would significantly impacts project efficiency, environmental safety, and long-term performance.
SGi Tech’s Captive Blasting offers an advanced, high-precision surface preparation method that eliminates contaminants on any hard surface, including steel and concrete, while maintaining a clean, dust-free environment. Unlike traditional abrasive blasting, which generates airborne particles and requires extensive containment measures, captive blasting captures debris instantly, ensuring a controlled and eco-friendly process.
At Sonicon, we utilize Captive Blasting to deliver safe, efficient, and environmentally responsible surface preparation across various industries, ensuring surfaces are optimally prepared for coatings, linings, and structural applications.
Captive blasting is a closed-loop abrasive blasting technique that propels steel grit or other abrasives onto a surface while simultaneously vacuuming away debris and contaminants. This method ensures a clean, dust-free work environment, making it ideal for projects in operational facilities or areas where contamination must be minimized.
Unlike conventional open blasting, captive blasting contains all spent media and waste materials within a controlled chamber, eliminating airborne pollutants and reducing clean-up time. The process effectively removes rust, old coatings, laitance, and contaminants while leaving behind a uniform surface profile (CSP 2–CSP 4) suitable for coatings, adhesives, and overlays.
- Dust-Free & Contained Process: Captures airborne debris instantly, ensuring minimal site contamination and allowing for safe work in occupied environments.
- Surface Consistency & Profiling: Provides a uniform CSP rating (CSP 2–CSP 4), ensuring better adhesion for coatings, paints, and protective linings.
- Enhanced Safety & Compliance: Eliminates airborne silica and hazardous dust, reducing worker exposure to harmful particles.
- Eco-Friendly & Waste Efficient: Reduces material waste and allows for the recycling of abrasives, minimizing environmental impact.
- Minimal Disruptions to Operations: Ideal for ongoing industrial, commercial, and marine environments where downtime must be minimized.
- Steel Structures & Pipelines
- Concrete Surface
- Oil & Gas Facilities
- Marine & Offshore Installations
- Food Processing & Cleanroom Facilites
- And many more!
