Sandmaster

What Sandmaster does

Sandmaster Gesellschaft für Spielsandpflege und Umwelthygiene mbH is a privately held German specialty-services company founded in 1991 and headquartered in Wendlingen am Neckar. The company is the inventor and market leader of mechanical sand cleaning, using its patented Sandmaster Process — a conveyor-belt and steep-screen separation system that cleans sand up to 40 cm deep — alongside high-pressure rotating-whirl systems for rubber/synthetic tracks and a mobile water filtration unit (Water Beast) that recycles wastewater on site and reduces freshwater consumption by up to 80%. Its core customers are municipalities, sports clubs, schools, and facility operators with sand playgrounds, athletics tracks, artificial turf pitches, and stone or concrete surfaces. Service quality is reinforced by TÜV-certified processes, DIN 1176 fall-protection compliance, and a patented SR Control depth-measurement system that produces documented before/after reports.

The business generates revenue primarily from on-site professional cleaning and repair services priced per project via website enquiry, complemented by hardware offerings such as the BUKY ONE autonomous electric artificial turf maintenance robot (launched October 2025), MASTER COVER custom-printed sand protection covers, the KotStop animal deterrent, and the HDR 200 small-area water machine. Sandmaster operates directly through wholly-owned subsidiaries in Germany, Austria, France, the Netherlands, and Sweden/Norway, and extends its reach through exclusive partner firms in the UK, Denmark, Finland, Estonia, Switzerland, Spain, Hungary, and Belgium. Distribution is anchored by trade-show presence (FSB Cologne), a multilingual website, social channels, and brand ambassadors including Olympic long jump champion Malaika Mihambo. The company is led by Managing Director Christoph Mayer-Klenk, is owner-managed with no outside equity, and reports no venture or private-equity backing.
