In one embodiment, the second barrier comprises a liner and a support. In a further embodiment, the support substantially secures at least a portion of the second barrier in the first barrier. ## Claims ### Claim 1 A drainage channel comprising: a first barrier for containment; and a second barrier for containment comprising: a first spacer bar and a second spacer bar, a support, said support defining first and second end portions, said first and second end portions being biased toward a corresponding side of said first barrier, said first end portion being secured to said first spacer bar and said second end portion being secured to said second spacer bar, wherein said support substantially secures at least a portion of said second barrier in said first barrier, wherein said support is formed from a rigid or semi-rigid material, and a liner, said liner defining first and second portions, said first portion positioned around said first spacer bar and secured to itself, said second portion positioned around said second spacer bar and secured to itself, wherein said liner is formed from a flexible material. ### Claim 2 (depends on 1) The drainage channel of claim 1, wherein said second barrier further comprises a fastener configured to substantially secure said liner to said support. ### Claim 3 (depends on 2) The drainage channel of claim 2, further comprising a sealant positioned substantially adjacent to said fastener to deter moisture from entering a space between said first barrier and said second barrier. ### Claim 4 (depends on 1) The drainage channel of claim 1, wherein the contour of the cross-section of said support is generally the same as the contour of the cross-section of said first barrier. ### Claim 5 (depends on 1) The drainage channel of claim 1, wherein said first barrier is generally U-shaped. ### Claim 6 (depends on 1) The drainage channel of claim 1, wherein said first barrier is formed from a material selected from the group consisting of a cementitious material and a polymer concrete. ### Claim 7 (depends on 1) The drainage channel of claim 1, wherein said liner is generally U-shaped. ### Claim 8 (depends on 1) The drainage channel of claim 1, wherein said liner is formed from a substantially seamless, monolithic material. ### Claim 9 (depends on 1) The drainage channel of claim 1, wherein said liner is formed from a polymer material. ### Claim 10 (depends on 1) The drainage channel of claim 1, further comprising a frame substantially secured to said first barrier and for supporting a drainage grate. ### Claim 11 (depends on 1) The drainage channel of claim 1, further comprising a sensor positioned between said support and said liner, wherein said sensor is configured to detect moisture. ### Claim 12 A method for constructing a drainage channel, the method comprising: forming a trench; placing a first barrier for containment at least partially in the trench; providing a second barrier, the second barrier comprising: a first spacer bar and a second spacer bar, a support for substantially securing the at least a portion of the second barrier in the first barrier, the support defining first and second end portions, the first end portion being secured to the first spacer bar and the second end portion being secured to the second spacer bar, wherein the support is formed from a rigid or semi-rigid material, and a liner, the liner defining first and second portions, the first portion positioned around the first spacer bar and secured to itself, the second portion positioned around the second spacer bar and secured to itself, wherein the liner is formed from a flexible material; and placing at least a portion of the second barrier for containment in the first barrier so that the first and second end portions of the support are biased toward a corresponding side of the first barrier. ### Claim 13 (depends on 12) The method of claim 12, further comprising securing a frame to the first barrier, wherein the frame is configured for supporting a drainage grate. ### Claim 14 (depends on 13) The method of claim 13, further comprising providing a grate and placing the grate on the frame. ### Claim 15 (depends on 12) The method of claim 12, wherein said second placing step comprises biasing the support inwardly until the at least a portion of the second barrier is in the first barrier and then unbiasing the support. ### Claim 16 (depends on 12) The method of claim 12, wherein said second placing step comprises fastening a fastener to the second barrier to substantially secure the liner to the support. ### Claim 17 (depends on 16) The method of claim 16, further comprising applying a sealant substantially adjacent to the fastener to deter moisture from entering a space between the first barrier and the second barrier. ### Claim 18 (depends on 12) The method of claim 12, further comprising placing a sensor between the support and the liner, wherein the sensor is configured to detect moisture. ### Claim 19 (depends on 1) The drainage channel of claim 1, further comprising a frame substantially secured to a top portion of said first barrier and for supporting a drainage grate, said frame defining a first frame portion that extends to vertically cover at least a portion of said first spacer bar and a second frame portion that extends to vertically cover at least a portion of said second spacer bar, said first and second frame portions securing said spacer bars within said first barrier. ### Claim 20 (depends on 1) The drainage channel of claim 1, wherein the liner is formed of a substantially seamless monolithic material comprising a polyester fiber weave coated in an ethylene inter-polymer alloy.
