***20H SYSTEM by EMSEAL GUIDE SPECIFICATION***

***Note to Specifier:

The 20H SYSTEM has been largely replaced for deck joint applications by the introduction in 2006 of the DSM SYSTEM

With its introduction in 2006 the DSM SYSTEM supersedes it's predecessors, 20H SYSTEM and DSH SYSTEM, in most applications. The DSM SYSTEM builds on a track record of over 30 years of sealing horizontal plane joints with impregnated foam sealants and is an evolution of EMSEAL’s earlier technologies.   The DSM SYSTEM features greater movement capability, dual sealing, a fuel resistant silicone bellows coating, greater movement capability, better low temperature flexibility, and improved high temperature stability.  It achieves these improvements through EMSEAL’s new cellular-acrylic impregnation technology and is free of any asphalt compounds.  Additionally, the DSM SYSTEM is totally free of wax or wax compounds. Consequently the suitability of the DSM SYSTEM is extended geographically as well as to applications such as in metal-angles, and top-decks previously not recommended for joint-face-adhered systems.

The 20H SYSTEM continues to have place in installations in below-grade, positive-side wall joints***
