PREPRUFE® Tieback Cover

Product Description

The PREPRUFE® Tieback Cover is a specially designed, two-part cover used to maintain waterproofing integrity at soil retention tieback heads. 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. A prefabricated, rigid ABS plastic base provides the strength and durability needed to withstand the pressure created by concrete placement. The prefabricated PREPRUFE® membrane cover ensures continuity of the advanced bond technology for the PREPRUFE® System..

Uses

The PREPRUFE® Tieback Cover can be installed over cable and rod type tieback heads. The base is mechanically fastened to the soil retention system and the cover is positioned over the base and integrated to the field membrane with PREPRUFE® Tape providing a continuous PREPRUFE® system for these difficult to detail areas.
