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 method of manufacturing a stormwater chamber, comprising steps of: providing a polymer melt;injecting a CO2 blowing agent into the polymer melt; andinjecting the polymer melt and CO2 blowing agent blend into a mold cavity to form a cellular plastic foam chamber, the formed chamber being an 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, and a rib provided on a plurality of the plurality of corrugation peaks, each rib having an arch-shaped cross-section with an outer surface extending outwardly from a corrugation peak and a fin extending inwardly from the corrugation peak, wherein each rib extends upwardly from one of the bases to a rib upper end, the 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 such that 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 method of claim 1, wherein each rib has the arch-shaped cross-section extending outwardly with the fin centered on and extending inwardly from the rib arch-shaped cross-section. 3. The method 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 method of claim 1, wherein the rib has a vertical height which is 30% to 80% of a vertical height of the chamber. 5. The method of claim 4, wherein the rib vertical height is 40% to 60% of the vertical height of the chamber. 6. The method of claim 1, wherein the channel minimum depth is located at the rib upper end. 7. The method of claim 3, wherein the rib arch-shaped cross-section decreases in size from one of the bases to the rib upper end. 8. The method of claim 1, 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. 9. The method of claim 1, 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. 10. A method of manufacturing a stormwater chamber, comprising steps of: providing a polymer melt;injecting a CO2 blowing agent into the polymer melt; andinjecting the polymer melt and CO2 blowing agent blend into a mold cavity to form a cellular plastic foam chamber, the formed chamber being an 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. 11. The method of claim 10, wherein the fin depth is less than the depth of the rib arch-shaped cross-section. 12. The method of claim 10, wherein the rib has a vertical height which is 30% to 80% of a vertical height of the chamber. 13. The method claim 12, wherein the rib vertical height is 40% to 60% of the vertical height of the chamber. 14. The method of claim 10, wherein the rib arch-shaped cross-section decreases in size from one of the bases to the rib upper end. 15. The method of claim 10, 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, 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. 16. A method of manufacturing a stormwater chamber, comprising steps of: injecting a polymer melt into a mold cavity to form a cellular plastic foam chamber, the formed chamber being an 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, and a rib provided on a plurality of the plurality of corrugation peaks, each rib having an arch-shaped cross-section with an outer surface extending outwardly from a corrugation peak and a fin extending inwardly from the corrugation peak, wherein each rib extends upwardly from one of the bases to a rib upper end, the 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 such that 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. 17. The method of claim 16, wherein each rib has the arch-shaped cross-section extending outwardly with the fin centered on and extending inwardly from the rib arch-shaped cross-section. 18. The method of claim 16, 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. 19. The method of claim 16, wherein the rib has a vertical height which is 30% to 80% of a vertical height of the chamber. 20. The method of claim 19, wherein the rib vertical height is 40% to 60% of the vertical height of the chamber. 21. The method of claim 16, wherein the channel minimum depth is located at the rib upper end. 22. The method of claim 16, wherein the rib arch-shaped cross-section decreases in size from one of the bases to the rib upper end.
