PRECOMPRESSED FOAM EXPANSION JOINT SYSTEM TRANSITION

摘要

A water resistant expansion joint system for installation into a building joint in vertical and horizontal configurations is designed such that it can be used for either an inside or outside corner. According to an aspect, the system comprises open celled foam having a water-based acrylic chemistry infused therein. A layer of an elastomer is disposed on the open celled foam and is tooled to define a profile to facilitate the compression of the expansion joint system when installed between coplanar substrates. The system is delivered to a job site in a pre-compressed state ready for installation into the building joint.

1. A water resistant expansion joint system, comprising:
foam; and a layer of an elastomer disposed on the foam; wherein the layer of the elastomer facilitates compression of the water resistant expansion joint system when installed between substrates; and wherein the water resistant expansion joint system is angled around a corner between the substrates, and the expansion joint system accommodates thermal and seismic movement in the system by expanding and contracting, and the water resistant expansion joint system is installed between the substrates and creates a waterproof seal around the corner upon expansion of the foam between the substrates.
