Abstract
Disclosed is a water resistant joint sealing system comprising a coiled, coated precompressed core material. In one embodiment, the joint sealing system includes a fire retardant material put into the core material. In one embodiment, the fire retardant material forms a layer in, or between portions of material of, the core material.
Claims11
A water resistant precompressed joint system comprising:
- a pre-compressed, coated core strip windable onto a device multiple times and including:
- a top coat on said core strip of an elastomeric water proofing material formed into an arched, or a dome profile transverse to a direction of compression of the core strip against the device;
- and
- a liner configured to hold the coated core strip in compression;
- wherein the pre-compressed, coated core strip is wound onto the device so that the pre-compressed, coated core strip with the liner overlaps the pre-compressed, coated core with the liner multiple times creating discrete layers of wraps and the liner is positioned to keep each wrap discrete from a next wrap to prevent adhesion between the layers of the wraps.

A water and fire resistant expansion joint system comprising:
- a pre-compressed, coated foam strip windable onto a device multiple times and including:
- a top coat on said foam strip of a water resistant material transverse to a direction of compression of the foam strip against the device;
- a fire retardant infused into the foam strip;
- and
- a liner configured to hold the coated foam strip in compression;
- wherein the pre-compressed, coated foam strip is wound onto the device so that the pre-compressed, coated foam strip with the liner overlaps itself multiple times creating discrete layers of wraps and the liner is positioned to keep each wrap discrete from a next wrap to prevent adhesion between the layers of the wraps;
- and
- wherein the foam strip with the fire retardant has as a density in a range of about 160 kg/m3 to about 800 kg/m3;
- and the water and fire resistant expansion joint system is configured to pass testing mandated by UL 2079.
6 more elements
A method of making a water resistant precompressed joint system comprising:
- coating a core material with a water resistant elastomer to form a coated sheet;
- cutting the coated sheet into a strip;
- forming the strip into an arched profile;
- and
- compressing the arched strip.
