The Terra-Tech Difference

The TT35HDS wet abrasive system’s operational flexibility makes it ideal for use across a wide array of use cases ranging from aggressive blasting (e.g. removal of heavy scale from industrial applications) to gentle surface cleaning without damaging, heating or warping delicate substrates (e.g. restoration of historical monuments & structures, aerospace components, etc.).

With reductions in abrasive consumption and airborne dust of 80–90% and >90% versus dry blasting, respectively, wet abrasive systems eliminate the burden, expense and hassle associated with dust containment, cleanup and disposal while maintaining comparable production rates with minimal impact on/to adjacent operations.

Save time by cleaning and preparing surfaces in a single step! The combined action of abrasives and water allow for the simultaneous removal of surface contaminants (e.g. corrosion products, dust and scale) and anchor profile generation without embedding particles on the substrate—salt removal and/or rust inhibiting chemical additives can be added to further enhance surface cleanliness.
