Short Description

Below-Grade Wall Expansion Joint

Quantity Needed

The 20H System is a tried and true preformed expanding foam sealant produced by impregnating permanently elastic, high density, open-cell polyurethane foam with an acrylic polymer modified, water-based asphalt emulsion. It is primarily used in below-grade applications. The architectural and engineering community has benefited from 20H System’s performance for over 30 years.

Note:  The 20H System has been replaced for deck joint applications by the DSM System and in below-grade applications by BG System and DSM-DS.  20H System still exists in legacy specifications and for installations in below-grade, positive-side wall joints.
