Bituminous coatings are widely used across industries for their waterproofing and protective qualities — from water tanks and pipelines to pavements and structural foundations. But as these coatings age, removing them becomes a significant challenge, especially when using traditional methods that are labor-intensive, environmentally risky, or surface-damaging.
This article draws insights from a recent Bitumen Removal Case Study (PDF) by Quantum Blast Technologies, showcasing how their RapidBlast™ wet abrasive blasting equipment delivers a clean, safe, and highly effective solution.

The Problem: A Legacy Tank with Toxic Risks
A farmer inherited a rural property with an old concrete rainwater tank coated with bitumen — a common waterproofing method in previous decades. However, concerns soon arose about the presence of polycyclic aromatic hydrocarbons (PAHs) in the bitumen, which can leach into water and pose health hazards as the coating degrades.
The challenge? Safely remove the aged bitumen from a delicate concrete surface without introducing new risks.
The Solution: Dustless Blasting with RapidBlast™
Enter RapidBlast™, a wet abrasive blasting system from Quantum Blast that combines abrasive media with water to cut through coatings while significantly reducing airborne dust and contaminants.
Unlike dry blasting or chemical removal — both of which can be messy, harsh, or hazardous — wet blasting provides a balanced, eco-friendly, and controlled approach.
Advantages of RapidBlast™ Wet Abrasive Blasting:
- Dust Suppression – The water element suppresses harmful dust clouds and PAHs during blasting.
- Effective Coating Removal – Removes bitumen efficiently from concrete, metal, stone, glass, and more.
- Substrate Protection – Gentle on surfaces, avoiding damage that’s common with dry blasting or pressure washing.
- Eco-Friendly – No chemical runoff, making it safe for use around homes, farms, and water sources.
- Flexible Abrasives – Garnet offers high-precision removal; fine crushed glass provides a cost-effective alternative.
Real Application: From Aged Coating to a Fresh Start
In the featured case, operators used garnet media to strip bitumen from the rainwater tank interior. The job was performed in a controlled setup to minimize waste and ensure safety.
The result?
- A clean, smooth concrete surface
- No structural damage
- Ready for recoating or safe water reuse
“The process exceeded expectations, providing fast, safe, and residue-free removal — a win for the environment and the user.”
Visuals in the case study clearly show the before and after transformation, highlighting the thoroughness of the RapidBlast™ system.
Why Quantum Blast’s RapidBlast™ Stands Out
Quantum Blast’s equipment is built for professionals who demand efficiency without compromise. Whether you’re tackling industrial tanks, public infrastructure, or agricultural storage, their wet abrasive blasting units offer:
- Rapid deployment
- Minimal training requirements
- Lower labor fatigue
- Compliance with safety and environmental regulations
Conclusion: The Better Way to Remove Bitumen
If you’re facing the challenge of removing old or degraded bituminous coatings, don’t settle for slow or risky methods. The wet abrasive technology behind RapidBlast™ not only protects your surfaces and workers but also ensures your job meets today’s safety and sustainability expectations.
