About stresan®

The history of stresan® – Kirchhellener Sand

A family history

For more than 75 years our family business is extracting sand and gravel from our sand pits in Kirchhellen. Formerly only for the construction materials industry – but in the beginning of the eighties we discovered that stresan® has unique features which characterize the ideal surface for equestrian sports.

After running some tests on our own and equestrian arenas in the near surroundings, the perfect sand mixture was found: today’s stresan® – Kirchhellener Sand! The new equestrian surface convinced riders from the surrounding area as well as the professionals. The at the time world’s most sought-after specialist for equestrian arena surfaces and builder of the Olympic equestrian riding grounds, Hermann Duckek, made our stresan® widely recognised beyond the borders of Europe which would prove to be our breakthrough as a superior supplier of sand for equestrian sports.

With the target to offer the perfect equestrian surface for every occasion, our sand and aggregates are undergoing continuous tests and optimization – a passion which is also shared by the next generation. Therefore the corporate values are spread and the constantly high quality of stresan® is guaranteed. A family history we are proud of.

Quality Pledge

We see our challenge in the production of equestrian surfaces that delight our customers and their horses! Thanks to our passion for continuous development and years of experience in the production of equestrian surfaces, we are able to fulfill the very different requirements of our customers. The consistently high quality of our equestrian sand is a matter of course for us.

For our equestrian surface mixtures we exclusively use certified fibres and high-quality woodchips that is particularly gentle on the horses’ hooves. All materials for our equestrian surfaces are thoroughly tried and tested to determine their effect on horse and the environment. The composition of the equestrian sand is individually adapted to the clients’ expectations and requirements.

In order for you to be sure that your equestrian arena surface is made from original stresan® – “Kirchhellener Sand”, all customers buying our equestrian sand will receive a certificate of authenticity for their surface.

stresan® – Kirchhellener Sand

Due to diverse geophysical influences, silica sands from different mining sites are carrying different characteristics – that’s why not every type of silica sand is designed to be used as a horse riding surface. stresan® – Kirchhellener Sand has inherently the best properties to be used as a riding surface.

The fine stresan® grain-size curve creates an excellent water retention capacity and only compacts the sand to such an extent that it offers horses‘ hooves optimal penetration and stability. At the same time, our silica sand is able to dispel excess water across the surface, where infrastructure allows.

In order to provide the ideal surface for each equestrian discipline we select the correct raw materials for pour customers and prepare the sand individually for its demanding tasks. This includes not only manufacturing the optimal grain size, but also selecting and mixing the appropriate aggregates such as woodchips or fibres. Depending on the riding discipline it may also be necessary to mix in other types of sand.


Equestrian sand is our expertise


Depending on the equestrian discipline and the existing foundation layer, the equestrian surface for outdoor riding arenas is chosen.


stresan® sand can be used as
all-purpose riding surface and may
also be adapted to the specificities of particular equestrian disciplines.


Equestrian sand for western riding
is especially developed to meet
high demands of western stunts like Rollbacks.


Walking areas which are regarded as resting places need to provide a tread layer with best features.

Tournaments and events

High Quality and immediate use –
this is the reason why major organizers rely on stresan®.


Professional construction, the right foundation layer and proper maintenance are essential for longevity.


We take care of your equestrian sand


To ensure that you always receive stresan® on time and in the best quality, we offer our clients a stresan® premium delivery service, provided by our own fleet of 16 vehicles in total.

Our drivers are specially trained to work on equestrian facilities. Even the most difficult driving routes and access conditions are no issues for us. We are able to tackle entrances to low arenas or narrow access routes thanks to our specially designed vehicles.

To our customers from 200 km distance onwards we also offer the stresan® standard delivery service at a reasonable price.


Equestrian surfaces have to be renewed after a certain amount of time. Whether it is natural sand or enhanced with woodchips or fibres: We will cost-effectively collect your stresan® equestrian surfaces and professionally dispose of them in an environmentally friendly way. We will also take care of the disposal of equestrian surface mixtures from other providers. Extra costs could, however, be incurred due to the often higher level of contamination from mixing in synthetic materials. When purchasing your equestrian surface you should therefore make sure that disposing of it will not become more expensive than buying it.

Frequently asked questions

Equestrian sand must have very special characteristics in order to be used as a riding surface. Our stresan® sand is unique in that its fine stresan® grain-size curve creates an excellent water retention capacity. This reduces dust accumulation and only compresses the sand to such an extent that it offers the hoof optimal penetration and stability. Our stresan® also has a very high silica content. A silica grain has a high degree of hardness, making it more resistant to grain pulverisation and abrasion, both of which lead to the accumulation of dust. The minimal amount of slurry materials is also a sign of the high quality of our sand.

We offer stresan® in a variety of mixtures. Depending on which discipline the surface is intended for and the requirements which need to be met, we mix fibres or woodchips into the sand. Our stresan® A does not, however, contain any additives and is therefore a purely natural product.

The type of the sand for the tread layer is in particular depending on your requirements:

  • Are you planning to build an outdoor or indoor riding facility?
  • Is there a focus on one equestrian discipline?
  • By how many horses is the arena used daily?
  • What material is used for the foundation layer?
  • Are there restrictions concerning structural or legal issues?

Your answers to these questions allow us to make a recommendation for your equestrian surface. Therefore we will be happy to advise you in a personal meeting or phone call, without any obligation and without any charge, of course.

For outdoor riding arenas we recommend a tread layer of 12 centimeters und in indoor riding arenas however a tread layer of 10 centimeters. In order to calculate the amount of sand needed, the size of the arena is multiplied with the specific weight of the sand and the high of the tread layer. Our example: outdoor riding arena with the dimensions 20m x 40m: (20,00 m x 40,00 m x 0,12 m) x 1,7t/m³ = 160 tons. For an outdoor riding arena with the dimensions 20meters x 40meters we recommend a quantity of approx. 160 tons of sand. This equals around six semitrailer trucks; minimal quantity variances during the process of loading are possible.

When used outside, stresan® A (without additional materials) dispels excess water across the surface, making the construction of a drainage system under the riding surface unnecessary. However, this is only the case when your area has a lateral slope of 1 to 2%. The foundation of your riding arena must also be stable and have a sufficient load-bearing capacity. Additionally, please ensure that there are no barriers at the end of the slope, as this can lead to a build-up of water. In contrast, our riding surfaces made from sand mixed with fibres or woodchips are very permeable to water and require suitable infrastructure. A further measure which is important when using equestrian sand is regular maintenance. The best way to keep your surface in good condition can be found in our maintenance instruction guide which is available via our download area. If you need any further assistance, please do not hesitate to contact us.
