Basalt is an extremely hard and dense volcanic rock that places special demands on processing. The best technique for cutting basalt is water jet cutting. This process uses a high pressure water jet, which is often reinforced with an abrasive material such as garnet sand, to penetrate the material and produce precise cuts.

Waterjet cutting is ideal for hard materials such as basalt, as it is a cold cutting technique that does not thermally stress the material. This prevents cracks, stresses or structural changes in the material. When cutting basalt, it also leaves a smooth, burr-free surface that requires no further finishing. At Eckert Cutting, we offer high-quality waterjet cutting machines that are ideal for processing such demanding materials.
