The principle of concrete roughening by ultra-high pressure water jet equipment:

Use of water cutting technology to pull out the rough surface with textures on the concrete base surface and inner wall board through high-pressure water. The tile glue can penetrate into the interior of the wall, making the tile and the wall more stable and reducing the base layer residual laitance, mold release agent, etc. produce hidden quality hazards of hollow drum.

Under the eroding action of the high-pressure water jet, the emulsified skin layer on the surface of the concrete quickly falls off, and the surface of the concrete becomes coarse sand to meet the requirements of surface treatment, so that the new and old concrete are tightly combined.

Note:

Different cement grades (concrete strength) require different water pressure.
