Abstract
A foundation comprising one or more layers or mattresses of tires, and a fill material provided within and/or between tires of each of the mattresses. The fill material is preferably a relatively coarse aggregate and provides a porous bed having relatively high drainage capacity. The lowermost mattress is cloth which is designed to allow the passage of water across the lowermost mattress whilst preventing the ingress of relatively finer material into the fill material and which can otherwise lead to degeneration of the foundation. At least some of the tires typically also have an upper sidewall removed therefrom.
Claims25
A foundation comprising one or more layers of tires including a lowermost layer being located adjacent to the ground, and a fill material having a preselected grade provided within tires of each of the layers, wherein at least the lowermost layer has a porous sheet positioned thereunder which is adapted for allowing the passage of water through the lowermost layer whilst preventing the ingress of matter of a grade finer than the fill material into the lowermost layer.
