Sandblasting

From storage tanks to profiling concrete HGS has the equipment and personnel capable of handling any type of project.  We use coal slag for most of our sandblasting need but if the job requires special results we will use any of these aggregates, Crushed Glass, Calcium Carbonate Limestone, Sodium Bicarbonate, Garnet, Starblast, Aluminum Oxide, Plastic beads, Glass beads, Corn Cobs, Walnut Shells, CO2 Dry Ice (see special page for dry ice blasting) and Sponge (see special page for sponge blasting).

Dry Ice Blasting

When the environment or substrate is sensitive Dry Ice blasting fits the bill.  Dry Ice Blasting serves almost any industry for components that need to be cleaned in a fast and safe way with little down time.  Aircraft and Aerospace, Automotive, Baking and Food Processing, Electrical and Power, Foundries, Medical and Pharmaceutical, Plastics and Printing.  All of these industries have specialized equipment and machines used in the manufacturing process or service and in the process of operations become contaminated with process materials or lubricants and the like.  Dry Ice blasting is an excellent choice for cleaning the contamination away from these moving parts maintaining proper manufacturing tolerances.

Factory repaints

One of the factors that limit the effectiveness of repainting a factory is insufficient surface preparation.  Ice blasting changes the game.  Now every surface can be prepared properly by removing surface contamination, loose paint, and other foreign materials.  There is no media or water to clean up after the cleaning, only the items removed by the Dry Ice Blasting.

Advantages of Dry Ice Blasting

Dry ice blasting is aggressive enough to remove paint but delicate enough to protect your investment. Cleaning with dry ice can clean grime, remove lead-based paint, and bring out original detail.

Unlike abrasive or chemical restoration methods, dry ice blasting does not scratch or stain the surface. Instead, it uncovers the underlying surface and restores a structure to its original state. Dry ice blasting is easy to control and reaches the tightest cracks and corners without damaging surrounding objects.

Dry ice blasting restores surfaces without leaving secondary waste behind. This eliminates the cleanup step that traditional abrasive techniques create. Since dry ice sublimates, or turns from a solid to a gas, there is no water to clean up either.

Dry ice blasting is safe for the environment because it does not use dangerous chemicals or leave hazardous fumes behind and is safe for workers since it is non-flammable and non-conductive.

Dry ice blasting accomplishes mold remediation faster and more completely than mechanical abrasion. Dry ice blasting does not require toxic chemicals and does not create a toxic dust hazard from remediation operations.

Dry ice blasting is safer for remediation operators and the environment because dry ice blasting removes and kills mold in one pass and creates no secondary waste.  Since the mold is killed instantly there is no secondary contamination.

Dry ice is a non-conductor of electricity, so live electrical equipment and wiring does not have to be removed or de-energized during the remediation process. HVAC equipment and duct work can be cleaned without extensive dismantling because dry ice will not damage the equipment.
