Replace
Directly use HydroRocca in existing stonewashing equipment without mechanical modification.
HydroRocca is the reusable stonewashing media to replace natural volcanic stone—bringing repeatable finishes, longer service life and less process waste to every load.

A flexible, controlled abrasive surface limits sharp impact in denim washing.
Achieves lower cost of labour, water usage, storage and transportation costs.
Uniform, consistent particle sizes support predictable batch-to-batch washing results.
A controlled material platform
Uniform engineered shape avoids broken sharp corners, preventing snags and scratches on denim fabric.
Consistent abrasion rate means media performance stays predictable across its full service life, with no sudden drop in effect.
Lower break-down rate reduces mineral sludge buildup inside the drum, cutting down frequent drum cleaning and labor.
Works well with low-water washing recipes, helping reduce overall wastewater discharge and treatment load.
