PA has 25,000+ bridges (most structurally deficient in the US). NJ has 6,800+. NY has 17,000+. DOT-specified coating removal and surface prep by laser. Coating-ready surface preparation with less containment complexity. See our laser surface preparation service.
The spent abrasive media used in blasting can become contaminated by lead, chromium, or other constituents from the removed coating. Whether it is hazardous—and whether TCLP testing, manifests, or regulated disposal are required—depends on the coating, test results, generator status, and applicable rules. Large bridge projects can also create substantial volumes of spent grit.
Laser cleaning avoids spent abrasive media and the containment, recovery, and blast-media disposal associated with it. Airborne emissions are controlled with source capture and HEPA filtration. Removed coatings, captured particulate, and filters must still be characterized and managed according to the actual material and project requirements. Surface acceptance and recoating timing remain subject to the project specification and inspector.
We are an EPA Lead-Safe Certified Firm for RRP-covered work within the certification’s defined scope. For bridge coatings, project-specific lead, environmental, worker-protection, and DOT requirements still apply. Laser cleaning adds no abrasive media, so there is no spent abrasive requiring blast-media TCLP testing or disposal manifests. Removed coating, captured particulate, and filters may still require testing, manifests, and regulated disposal based on their classification.
