Preprufe Tieback Covers are specially designed, two-part covers used to maintain waterproofing integrity at soil retention tieback heads. A prefabricated, rigid ABS plastic base provides the strength and durability needed to withstand the pressure created by concrete placement, and the prefabricated Preprufe membrane cover ensures continuity of the Advanced Bond Technology for the Preprufe System. The Preprufe Tieback Cover consists of a base and cover, and is assembled on site to provide a simple and quick waterproofing detailing aid used with the Preprufe System.
