For more than 40 years, the ground-breaking Crystalline Technology of Xypex Chemical Corporation has been serving concrete users around the world.
The new 12-story Alley 111 mixed-use high-rise in downtown Bellevue, Washington included a LEED-point eligible water retention vault to capture and store stormwater per the city’s building code. This structure was constructed using a blind-side shotcrete method with Xypex Admix C-500 to ensure that it is watertight.
Constructed of reinforced concrete, the tower has a square cross section that is 8 feet wide and 8 feet high on the inside with 2 foot thick wall, floor, and roof sections. More than 30,000 lbs of Xypex Admix C-500 were used in the construction of the structure.
The building’s roof includes a solar thermal water heating system and has a seating capacity for 425 people.Xypex Admix C-500 NF was included in 360 cubic yards of concrete used for the construction of the surge tanks.
In total, the team coated 16,000 square feet of concrete with Xypex Concentrate and Megamix I and repaired 3,600 square feet with Megamix II. 900 linear feet of construction joints were also repaired with Patch'n Plug.
