Foundation construction using recycled tire walls

DETAILED DESCRIPTION Referring to the accompanying drawings, there is illustrated a substrate layer generally indicated by reference numeral 10 for use in constructing a foundation 12.
The foundation 12 is placed over the ground 14 for supporting loads thereon, such as the foundation on roadways or parking lots.
The substrate layer 10 is placed directly over the ground 14 such that aggregate material 16 such as gravel may be placed thereon.
Concrete 18 is then poured over the aggregate material to complete the foundation 12.
The substrate layer 10, acts to prevent the aggregate from penetrating into the ground 14.
The substrate layer 10 accomplishes this by distributing the loads from the aggregate material 16 evenly over the ground 14 while permitting water to drain therethrough.
The substrate layer 10 comprises a substantially planar surface 20 formed from a plurality of generally flat and overlapping annular members 22 which are laid on the ground.
Each annular member 22 is formed from a respective side wall 24 of a recycled automotive tire 26.
A circular cut 28 is formed within each side wall 24 of the tire when the members 22 are initially formed.
The resulting annular member 22 includes a bead 30 and the side wall 32 of the tire.
A circular opening 34 is defined in the annular member 22 by the bead 30.
A bead wire which extends through the bead 30 thus remains intact and covered for strength and durability of the resulting annular member which is formed.
The annular members 22 are positioned on the ground 14 in an overlapping arrangement along the planer surface 20.
As seen from above in FIG.
1 the annular members 22 are laid out in an ordered and staggered pattern while the circular openings 34 defined within each annular member remains clear from obstruction from adjacent overlapping annular members to permit drainage of water therethrough.
This creates an arrangement in which each side wall portion has portions lying on the ground and portions 41 overlapping with an already laid side wall
