Case study

25% less budget, 40% less time, 50% less abrasive.

A blast contractor had a difficult blasting challenge and was looking for a solution. They had been contracted at short notice to blast a military oil storage tank but had a very short time frame to complete the job, 2 weeks instead of the usual 3.

With the switch to GMA Garnet 30/60, not only did they finish a day ahead of the shortened timeline, they used 50% less abrasive.
