Chem Link Curb System for Penetration Seals
........creates a tough, 2-inch deep poured rubber seal. A curb is bonded to the roof surface (EPDM, PVC, BUR, coal tar, SBS mod bit, granulated APP, many types of coated metal, metal flashing details and FRP), creating a form for the rubber seal and protecting it from ice or mechanical damage.

Curb components are made of precast polyester structural urethane and can be configured to fit every shape and size of penetration.

M-1™, the bonding adhesive included in the ChemCurb System, is a tough, thermosetting adhesive capable of bonding steel deck to bar joists and metal sandwich panels to roof and wall purlins. M-1 develops 300 lbs. per square inch of shear strength on metal, masonry and wood. It is capable of 300% elongation and can accommodate dimensional changes in construction materials down to minus 20 degrees F, and is solvent free.

1-Part™ Pourable Sealer is a moisture-cure self-leveling high performance sealer applied with a 1-quart caulking gun. It's designed for use in warranted ChemCurb penetration seals, and can be used in non-warranted metal pitch pans. Available in Gray only.


Chem Link E-Curbs E-Curbs are environmentally friendly, as they are made with far less material than the original ChemCurb design. These latest version ChemCurbs may be flashed or not as the situation calls for.
