When the builder of a massive $140-million underground water reservoir needed to fill every single crack with epoxy, they turned to Angelus to perform the work. The reservoir, built for owner Los Angeles Department of Water and Power, has a 55 million gallon storage capacity. Construction specifications called for the filling of all cracks .004" across or larger. That is about the thickness of a human hair.
Although cooling tubes were installed to minimize cracking during the curing process, the elimination of all shrinkage cracks was not possible. Following each pour, the walls, slab, and lid were all thoroughly inspected, and all cracks were identified and marked. Angelus injected more than six miles of Sika Epoxy.
In order to meet the EPA requirement that all open reservoirs be covered by the end of the year, or face steep fines, speed of construction was critical. Due to the aggressive scheduling strategy, 20 injection tradesman worked on the project. Through efficient coordination, proper man power, including multiple shifts and overtime, Angelus was able to successfully complete the scope of work while meeting the demanding project scheduling requirements.
