An arch-shaped corrugated chamber having corrugation peaks and valleys, with reinforcing ribs provided on the corrugation peaks. The ribs extend upwardly from a chamber base to a rib upper end, and have an arch-shaped cross-section with an outer surface extending outwardly from a corrugation peak and a fin extending inwardly from the corrugation peak, and optionally, a rib line provided on the rib outer surface centered on the rib arch-shaped cross-section. A channel formed by the inner surface of the rib is sized to receive a corresponding rib of a second chamber so that multiple similar chambers with ribs may be stacked together.

1. A chamber, comprising: a plastic arch-shaped corrugated chamber having a plurality of corrugation peaks and a plurality of corrugation valleys distributed along a length of the chamber, the corrugation peaks and corrugation valleys extending transverse to a lengthwise axis of the chamber, the chamber having a top portion and two side portions, with a base at a lower end of each side portion; anda rib provided on a plurality of the plurality of corrugation peaks, each rib having an outer surface extending outwardly from a corrugation peak and a fin extending inwardly, wherein each rib extends upwardly from one of the bases to a rib upper end,a rib having a depth and the fin having a depth, the rib depth and the fin depth tapering from a greater depth adjacent to the one of the bases to a lesser depth above the one of the bases;whereby the rib and the fin define a channel sized to receive a corresponding rib of a second chamber, the channel having a depth varying from a maximum depth adjacent the one of the bases to a minimum depth adjacent a location above the one of the bases. 2. The chamber of claim 1, wherein each rib has an outwardly extending arch-shaped cross-section with the fin centered on and extending inwardly from the rib arch-shaped cross-section. 3. The chamber of claim 2, wherein the rib arch-shaped cross-section has a depth and the fin depth is less than the depth of the rib arch-shaped cross-section. 4. The chamber of claim 3, wherein the rib arch-shaped cross-section and the fin define the channel. 5. The chamber of claim 4, wherein the channel minimum depth is located at the rib upper end. 6. The chamber of claim 3, wherein the rib arch-shaped cross-section decreases in size from one of the bases to the rib upper end. 7. The chamber of claim 2, wherein a rib line is provided on the rib outer surface centered on the rib arch-shaped cross-section and aligned with the fin. 8. The chamber of claim 1, wherein the rib has a vertical height which is 30% to 80% of a vertical height of the chamber. 9. The chamber of claim 8, wherein the rib vertical height is 40% to 60% of the vertical height of the chamber. 10. The chamber according to claim 1, wherein said chamber is formed of a cellular plastic foam. 11. A chamber, comprising: a plastic arch-shaped corrugated chamber having a plurality of corrugation peaks and a plurality of corrugation valleys distributed along a length of the chamber, the corrugation peaks and valleys having a thickness, the corrugation peaks and corrugation valleys extending transverse to a lengthwise axis of the chamber, the chamber having a top portion and two side portions, with a base at a lower end of each side portion; anda rib provided on a plurality of the plurality of corrugation peaks, each rib having an arch-shaped cross-section extending outwardly from a corrugation peak and having an outer wall, each rib further having a fin extending inwardly from a center of the rib arch-shaped cross-section,each rib extending upwardly from one of the bases to a rib upper end;the rib arch-shaped cross-section having a wall thickness and a depth, and the fin having a depth;the fin depth being greater than the arch-shaped cross-section wall thickness at a location adjacent to the one of the bases;the rib arch-shaped cross-section depth and the fin depth tapering from a greater depth adjacent to the one of the bases to a lesser depth above the one of the bases;whereby the rib arch-shaped cross-section and the fin define a channel sized to receive a corresponding rib of a second chamber, the channel having a depth varying from a maximum depth adjacent the one of the bases to a minimum depth adjacent a location above the one of the bases. 12. The chamber of claim 11, wherein the is less than the depth of the rib arch-shaped cross-section. 13. The chamber of claim 12, wherein a rib line is provided on a rib outer surface centered on the rib arch-shaped cross-section and aligned with the fin. 14. The chamber of claim 12, wherein the rib has a vertical height which is 30% to 80% of a vertical height of the chamber. 15. The chamber of claim 14, wherein the rib vertical height is 40% to 60% of the vertical height of the chamber. 16. The chamber according to claim 12, wherein said chamber is formed of a cellular plastic foam. 17. The chamber of claim 11, wherein the arch-shaped cross-section wall thickness is 0.375 inch and the depth of the fin is 0.625 inch at the location adjacent to the one of the bases. 18. The chamber of claim 11, wherein the depth of the fin is 0.625 inch and the depth of the arch-shaped cross-section between the outer wall of the arch-shaped cross-section and an inner wall of a corrugation peak is 1.375 inch at the location adjacent to the one of the bases. 19. A stormwater chamber, comprising: an elongated body with a top portion, a first side portion, and a second side portion and a generally arch-shaped cross-section;a base at a bottom of each of the first and second side portions;a plurality of circumferential reinforcing members disposed along a circumference of said elongated body; anda rib provided on a plurality of the plurality of circumferential reinforcing members extending upwardly from one of the bases to a rib upper end, each rib having an arch-shaped cross-section having an outer surface extending outwardly from a corrugation peak of the plurality of circumferential reinforcing members and a fin extending inwardly from a center of the rib arch-shaped cross-section, the fin having a depth which is less than a depth of the rib arch-shaped cross-section; the rib arch-shaped cross-section decreasing in size from the one of the bases to the rib upper end. 20. The stormwater chamber of claim 19, wherein the rib arch-shaped cross-section and the fin define a channel, and the rib arch-shaped cross-section depth and fin depth taper from a greater depth adjacent to one of the bases to a lesser depth adjacent to the rib upper end, the channel having a depth varying from a maximum depth adjacent the one of the bases to a minimum depth adjacent a location above the base. 21.
