[000109] Figure 5 depicts an assembly of a plurality of one piece water permeable pavers 10a- 10d connected together according to one or more embodiments.

[000110] One piece water permeable paver 10a can be connected to one piece water permeable paver 10b using the locking tabs and fastening slots.

[000111] One piece water permeable paver 10a can be connected to one piece water permeable paver lOd using the locking tabs and fastening slots.

[000112] One piece water permeable paver 10b can be connected to one piece water permeable paver 10c using the locking tabs and fastening slots.

[000113] One piece water permeable paver 10c can be connected to one piece water permeable paver lOd using the locking tabs and fastening slots.

[000114] Figures 6A depict the bottom and top of the one piece perm

[000115] In embodiments the one piece water permeable paver 10a has a fastening slot 40a.

In proximity to the fastening slot 40a can be one or more bottom snap locking portion 171a and 171b. The bottom snap locking portion 171a and 171b may be proximate to a bottom of the once piece permeable paver 10a.

[000116] In embodiments, the one piece water permeable paver 10a has a locking tab 42a. In proximity to the locking tab 42a can be one or more top snap locking portion 172a and 172b. The top snap locking portion 172a and 172b may be proximate to a bottom 22 of the one piece permeable paver.

[000117] The bottom snap locking portion 171a and 171b can include a bottom snap locking planar surface, such as bottom snap locking planar surface 173a. Similarly, top snap locking portion 172a and 172b can include a top snap locking planar surface, such as 14

top snap locking planar surface 174a.

[000118] Figure 6B depicts cut view of a first one piece water permeable in connection with a second one piece water permeable paver.

[000119] As the pavers 10a and 10b are connected together, bottom snap locking portion 171a and 171b and top snap locking portion 172a and 172b may be movingly engaged with respective snap locking tapered surfaces 175 and 176, as would be apparent to one of skill in the art. Once the one piece water permeable pavers 10a and 10b are connected together, the bottom and top snap locking planar surfaces 173a and 174b may be engaged. The use of the bottom and top snap locking planar surfaces 173a and 174b can provide additional load support and distribution with connected pavers 10a and 10b.

[000120] The locking tab 42b can include a rounded inner load surface 51b. The rounded inner load surface 51b can be configured to smoothly engage a corresponding rounded inner surface 99a of first paver outer wall 100a, such as at contact point 177.

[000121] The load surface 51b can have a slope that matches an outer wall 100a surface curvature for its inner surface 99a, which can enable locking tab 42b to mate with the corresponding surface 99a proximate to the fastening slot 40a.

[000122] An outer sloped edge 53b can have a curvature complimentary to the outer wall 100a curvature for outer wall surface 101a, which can enable to the pavers 10a and 10b to come into contact at contact point 178.

[000123] In embodiments, the one piece water permeable paver can be made from recycled plastics, such as milk bottles.

[000124] In embodiments, the one piece water permeable paver can be pigmented with soy based pigments to be environmentally friendly. [000125] Installing the one piece water permeable pavers can be a simple six step process.

[000126] The process can include clearing and grading a ground surface, as the first step. This clearing and grading can be done by hand with a shovel for a small area or with a bulldozer for a large area.

[000127] The process can include laying and spreading ½ an inch to 8 inches of ½ inch to 1 and ½ inch diameter rock or gravel onto the cleared and graded ground, as the second step. This laver of rock or gravel can be compacted or compressed with a roller or compactor.

[000128] The process can include preassembling the one piece water permeable pavers into four interconnected pavers with the locking tabs interlocking into the slots, as the third step.

[000129] The process can include placing the preassembled one piece water permeable pavers over the compacted or compressed rock or gravel, as the fourth step.

[000130] The process can include dumping the aggregate into the cells of the one piece water permeable pavers, as the fifth step. From ¾ inch to 1 and ½ inch rock, recycled asphalt, or other aggregate can be used to evenly fill the cells.

[000131] The process can also include compacting the filled cells, forming a parking lot or traffic surface ready to use for 25 plus years without maintenance, as the sixth step.

[000132] A process to create a stabilized water permeable grass parking or traffic surface can include performing steps one, two, three and four as described above. After laying the pavers, the process can include filling the cells of the one piece water permeable pavers with soil instead of aggregate and installing seed or sod as desired.

[000133] Foot paths can also be created with the one piece water permeable pavers. Any path can be made with the one piece water permeable pavers.

[000134] While these embodiments have been described with emphasis on the embodiments, it should be understood that within the scope of the appended claims, the embodiments might be practiced other than as specifically described herein.
