Grit Blasting & Abrasive Cleaning
Gumthorn offers expert grit blasting and abrasive cleaning services nationwide, supporting a diverse range of structures and sectors. Our work includes bridges, subways and tunnels, manholes, inspection chambers, steel frameworks, concrete elements, masonry constructions, and both multi-storey and underground car parks.
We deliver comprehensive surface preparation and abrasive blasting solutions, utilising a variety of advanced techniques to suit different project requirements, environments, and safety considerations:
Dry Grit Blasting
A powerful, traditional method using compressed air to propel abrasive media (such as steel grit, garnet, or aluminium oxide) for effective removal of rust, old coatings, scale, and contaminants, ideal for achieving a high-quality surface profile on steel and concrete.
Wet Blasting
Also known as vapor or slurry blasting, this combines abrasives with water to minimise airborne dust, reduce heat buildup, and provide gentler cleaning while still delivering excellent results on sensitive or enclosed areas.
Sponge Blasting
An innovative, low-dust system that uses sponge media embedded with abrasives; it compresses on impact to release the grit, then re-expands to trap dust and debris, offering up to 95-99% dust suppression, reusability of media, and suitability for occupied or environmentally sensitive sites.
Vacuum Track Blasting
Also known as containment/vacuum blasting), this features integrated vacuum recovery at the blast head to capture spent media, dust, and removed materials instantly, enabling near dust-free operations, efficient media recycling, and compliance in confined or regulated spaces.
These methods ensure thorough surface cleaning, rust and coating removal, and optimal profiling to prepare substrates for protective coatings, repairs, or further treatments. By selecting the right technique for each scenario, Gumthorn minimises environmental impact, enhances worker safety, reduces project downtime, and achieves durable, long-lasting outcomes tailored to structural and industrial demands.
