1. Giving the foundation a 1-2% incline will eliminate any need of further drainage.
2. The basic layer is appr. 15 cm thick and consists of mineral with a grain size of 5-45 mm (limestone gravel, recycled stone or asphalt)

3. The following interface layer is made of finer material, such as sand with 0-5 mm.
4. The final Hippotex layer needs some time to settle. Its particles will interlock thus offering an optimal grip. This process is accelerated by riding and humidity
