Summary and Description:

The Bridge and Highway Traffic-Grade Compression Seal (CSBHT) is composed of an open micro-cell polyurethane foam impregnated with a hydrophobic polymer sealing compound. It has been developed to meet the high performance needs of state and federal DOT projects.

The CSBHT seals have constant internal forces built into each cell. These cells continuously push against each other and the sidewalls of an opening to provide a permanent, watertight seal, eliminating costly water damages as well as allowing for a greater degree of joint movement. The seal incorporates a factory applied traffic-grade silicone coating on one side of the foam seal.

The CSBHT system provides a waterproof, dustproof, airtight, UV stable, chemically resistant, soundproof and insulated primary seal. Once the CSBHT is installed in the joint, the material expands depending on temperature, adapting to the width of the joint and the irregularities of the substrate provided such profile changes are not sudden or extreme.

Recommended for use in applications in the horizontal position, where there needs to be resistance to typical roadway traffic or chemicals found on roadways, bridges, garages, plaza decks and other areas that may be a concern.
