BSFH publishes Corona position paper

Sandmaster is a professional and market leading sand cleaner and member of the Bundesverband der Spielplatzgeräte- und Freizeitanlagenhersteller e.V. (BSFH), which has now published a Corona position paper, in which local authorities, federal states and also the federal government call for strong and sustainable promotion of modern, publicly accessible children’s playgrounds and outdoor fitness facilities over the next three years.

Sandmaster is a professional and market-leading sand cleaner and is a member of the Bundesverband der Spielplatzgeräte- und Freizeitanlagenhersteller e.V.

With or after the Corona crisis it is all the more important, in urban areas with their growing population and the dwindling number of leisure areas due to inner-city densification, that such areas are available in sufficient numbers and with attractive facilities.

Sandmaster brand ambassador Malaika Mihambo trains with Carl Lewis

Sandmaster brand ambassador Malaika Mihambo trains with Carl Lewis

Our brand ambassador, Malaika Mihambo, will in future train with nine-time Olympic champion Carl Lewis. This becomes known from a report of the DLV and own press release. Carl Lewis is also known as the athlete of the century, has set several world records and dominated the world elite in sprint and long jump from 1983 to 1996.

Now he wants to lead Malaika Mihambo, who will train in the USA in the future but will spend her rest periods in Germany, to great mental strength and sporting success. If everything goes well, training will start in August this year. You can also read details here:

We wish Malaika good luck for the upcoming training and of course for future competitions!

Sand cleaning: How important is the depth of cleaning?

Sand cleaning: How important is the depth of cleaning?

Sandmaster has been cleaning sand for almost 40 years, so we have a lot of experience. In many years dozens of studies have been made about the “cleanliness” of sand. Our sand cleaning machines are regularly certified by TÜV, we periodically have our #sandmaster process certified and we have commissioned microbiological expertises several times.

The cleaning process (sand master process)

Our patented process is based on a special separation process of organic and inorganic particles with a diameter from approx. 5 mm (broken glass, leaves, cigarette butts, animal excrement, coins, toy parts and other waste). All the sand is taken up to a depth of 40 cm (depending on the depth of pouring) and thrown against a steep screen by means of a conveyor belt. In the process, fine-grained materials, i.e. the sand, pass through the sieve and fall back to the ground. All other parts scrape off the sieve and land in a special collection basket and are then disposed of.

Fall protection according to DIN EN 11 777

As hard and hard sand on playgrounds or in diving pits or volleyball fields is a bad protection against falls, this must be counteracted. Thanks to the sand master process, our machines achieve a continuous cleaning depth of up to 40 cm, which in turn means that the sand is circulated, loosened and aerated to the maximum depth. This also brings us to the important point of hygiene…

Evaluation of hygiene

The sand master process significantly reduces the number of aerobic, colony-forming units. However, it is crucial that the organic components (faeces, leaves) are selectively removed, as these have a germ density that is around ten thousand times higher than that of the surrounding sand. The depth of cleaning is also a decisive criterion. Coli bacteria grow especially in the lower sand layers. Organic material present there is no longer decomposed and rotten due to the lack of oxygen. Circulation to a depth of 30 to 40 cm aerates the sand in such a way that a stable biological balance is established after a short time. Disinfection of the sand by chemical means or thermal processes would destroy the natural balance and would have to be repeated every 14 days. Optionally, the product “Sandmaster KotStop” can be applied, which greatly reduces the contamination by animal excrements (on a purely biological basis).

A surface cleaning with a depth of for example only 10 cm is not comparable with the depth cleaning described here and is therefore only a “cosmetic” treatment.


In our report, the investigating institute concludes as follows:
“…in the case of other sand cleaning devices, which only shake and grind the sand including impurities through horizontally mounted sieves, a lasting improvement in quality from a hygienic point of view is not to be expected. Even a cleaning depth that is too shallow will only bring about a slight improvement in quality. The Sandmaster process is a recycling of sand and saves the complete and also expensive sand replacement for years!

Malaika Mihambo success with Herzsprung

Malaika Mihambo success with Herzsprung

Malaika MihamboMalaika Mihambo, the Sandmaster brand ambassador and winner of the gold medal in the long jump, has been making children mobile since the schools, sports grounds and playgrounds were closed and offers a small sports program for at home on her YouTube live channel every day together with the “Starkmacher” club. The offer is primarily aimed at primary school children, but of course anyone who feels like it can take part.

On YouTube, she currently presents small challenges and tasks for the children every day at 10:00 am under a regularly changing motto. “Especially in these times movement is so important for the children, the children need distraction, structure and in the best case they learn something”, says the 26-year-old athlete.

We can only recommend this program for children and are thrilled with how much joy and commitment Malaika creates the program, live from home from your living room.

Malaika Mihambo is a great hope for the Olympics. Due to the crisis it was postponed to next year and therefore she still has a hard training year ahead of her. When Malaika will be able to start training again is not yet clear, but it could be soon.

Sandmaster supports Malaika Mihambo

Sandmaster supports Malaika Mihambo

Malaika Mihambo won World Championship gold for Germany in Doha (Qatar) in October 2019 with a fantastic 7.30 m long jump. Then she was awarded as Sportswoman of the Year 2019, which are only her current successes.

Sandmaster congratulates Malaika and wants to support her for at least the next two years. We are convinced that we will see much more of this exceptional young talent. And we have more in common than it seems, but more about that later…

Sandmaster cleans and maintains sports surfaces such as sand, gravel, synthetic surfaces and artificial turf. The areas tartan track / run-up track as well as the sand filled jumping pit are not only immensely important for children’s and leisure sports, but even more so for top athletes such as Malaika Mihambo. Malaika not only needs the perfect grip at the inrun, but also sand that has been aerated and cleaned according to the #sandmaster method, which guarantees protection against falling and thus reduces the risk of injury.

We are happy that we can work together with Malaika for the next two years and keep our fingers crossed for the next events!
