The images below show the assemblies of both detention basins. The video shows a leak check of the drainage area. The basins were constructed out of a 0.08" thick acrylic sheet. Each piece was cut using a jig saw and joined using caulk and Maximum Strength Construction Adhesive Gorilla Glue. Tape was applied first to ensure the correct angles between pieces before caulking and gluing them together. Next, caulk was applied to fill any openings between pieces, and glue was applied on top to solidify the intersections. Wood wedges were used to prop up the edges of the basins while drying to hold them steady. The basins are 1" deep and have a 1.5" wide rectangular hole for the outlet structures. The drainage area was waterproofed using one coat of Thompson's WaterSeal. This was applied using a brush.

Video of Leak Testing. The video shows water being poured on the drainage area of the table. The water pours out to the catchment bucket, and all water beads up on the surface of the plywood instead of seeping in, verifying that the waterproofing measures were sufficient. As discussed in the context section above, to waterproof this area one layer of waterproofer was applied to the surface, and all intersection points were caulked multiple times to give sufficient coverage.
