The invention relates to a method for foundation of a sports area, the method comprising the steps of: providing a first mixture of cement and particulate stone material; mixing said first mixture with a predetermined amount of water for forming a second mixture; applying a layer of said second mixture to a surface located at the place where the sports area is intended to be situated; curing/setting said layer of said second mixture applied to the surface, wherein the cured layer is porous and allows water to flow through said cured layer; and applying a layer of a particle size fraction onto said cured layer after the step of curing. The invention relates also to a mixture for foundation of a sports area, the mixture comprising cement and particulate stone material, wherein said mixture comprises ca.15-40% by dry weight cement and 60-85% by dry weight particulate stone material, suitably 20-35% by dry weight cement and 65-80% by dry weight particulate stone material, and more suitably 30% by dry weight cement and 70% by dry weight particulate stone material, and wherein at least 75% of said particles of said particulate stone material are of sizes within the range 0.1-10mm. |
