Base layer

For outdoor arenas a 6 inch layer of mineral aggregate (gravel of 0…1.5 inch grain size) will suit perfectly as substructure. Differing from region to region local civil engineering companies will supply this at 3 to 5 €/square meter. 
After riddling, this mineral aggregate surface should be level, closed, and rough. What is important is that water can penetrate this layer. 

For indoor arenas a rough-surface subfloor, such as rough concrete or dry, load bearing top soil with stone chippings rolled onto, will do as a substructure. What is important is that the surface is not smooth. Otherwise the flakes will slip away. A mineral aggregate base layer is not required.
 Do not lay foil or geotextile separating layers between ASground® and substructure! ASground® needs to „hold on“ to the substructure.

As a riding arena border it is best to use "ASaround"!

This riding arena border has been specially developed by us because in our eyes conventional boundary materials such as railroad sleepers, all round logs or even steel crash barriers represent too high risks of injury to horses and riders.

Our ''riding arena border ASaround'' offers maximum security. It is weather resistant and easy to clean and quickly assembled by a useful modular system. Moreover it will not become waterlogged because the water can flow through special recesses.


An ASground® all-season riding arena is a one-time investment, costs are transparent and clear:

Treading layer

ASground® costs 10.50 € (plus VAT, if applicable) per square meter.

We recommend a 7 inch layer (the above mentioned price refers to this height of pile). This bulk compacts during use to a 4 inch layer.

An 800 square meter riding arena would cost 800 x 10.5 € = 8,400.- € (plus VAT, if applicable).

Our carrier currently charges 1.65 € per driven kilometer (to and fro).  A single load is 620 square meters maximum.
Currently we have factories at Osnabrück, Regensburg, and Schwandorf. However, we will expand in order to cut distances travelled.

Example: Transport from Osnabrück in the metropolitan area London: 1,300 €.

These are one-time costs, since an ASground® neither rots away nor degrades with use. There are no operating costs caused by regular change of the top layer!

Depending on how intensively the riding arena is used, refilling of some 20 percent of the flakes is recommended after about ten years in order to ensure full elasticity of the material.


There is no disposal in the conventional sense as the ASground® material simply doesn’t wear out. This question arises only if you give up riding, and it can be answered easily:  sell it or give it back to us! Even after many years of service ASground® still is fully operational.
 Please compare for yourself the one-time and current costs of an ASground® vs. a sand riding arena.

We are expanding and will be glad to co-operate with distributors in the Netherlands, in Great...
