ChemLink ChemCurb was developed to address the most common source of leaks - Roof penetrations. Pipes, mechanical equipment, vents, solar panels and lightning protection are examples of penetrations which, in time, will create avenues for water. Repeated cycles of load, heat, cold, moisture, water ponding, and ultraviolet inevitably degrade pitch pans, rain caps, boots and other types of seals aimed at preventing leaks.
The ChemLink ChemCurb System replaces the old style metal pitch pans with versatile precast curb components, pourable sealant, and structural adhesive/sealant. The system can usually be installed in under 15 minutes and eliminates the need for flashing or mechanical attachment.
The ChemLink ChemCurb System is designed for use on granulated modified bitumen, PVC, PIB, TPO single ply, asphalt, and coal tar B.U.R. Please note that TPO Primer must be used on TPO substrates.
The ChemCurb system forms a durable waterproof rubber seal around penetrations of any size. An extended warranty against leaks is activated when CHEM LINK Construction & Maintenance receives a completed warranty card and proof of purchase.
ChemLink ChemCurb precast form components are composed of gray polyester resin. The ChemCurb is 2-inches high and is available in a variety of shapes and sizes. Bisected circular curbs have an inside diameter of 7½ or 5-inches. Straight pieces are available in 6 and 12-inch lengths and combine with 2-inch radius corners to create larger sizes. The outer surface is impervious to ice, corrosion, UV (ultraviolet light), and ponding water.
The Chemlink ChemCurb System - Advantages
Rapid installation - reduces labor significantly.
Excellent adhesion to most roofing materials.
No flashing or mechanical attachment required.
1-Part® pourable sealant accommodates movement and is suggested for use on all granulated membranes and details with excessive movement.
For sloped roof applications, substitute DuraLink™ non-slump adhesive/sealant for M-1® Structural Sealant/Adhesive and 1-Part Pourable Sealant
Sealant is flexible down to -40°F (-40°C).
Service Temperature -40°F to 200°F (-40°C to 93°C)
Chemlink ChemCurb System Components
ChemCurb exterior rings, straights, and corners.
M-1 Structural Adhesive/Sealant used for bonding the ChemCurb components, sealing and priming the penetration.
1-Part Pourable Penetration Sealant or PRO PACK™ two-part urethane pourable sealer. Both sealants are used to form a durable, water-tight seal around the roof penetration.

I spoke with the person in the Technical Support department who listened and understood my complicated circumstances and made the perfect recommendation. I received the product within a couple of days and before the weekend ended, the job was complete and I am very pleased with results. Thank you, Eco Building Products for your support and product recommendation.
The staff gave me good advice on how the products work and which ones to use. And they shipped it here really fast.

The product arrived on time and was packaged carefully. Very happy with the quality of the build as well!
Adam B.07-06-25
Packed well, arrived quickly and installed in a cinch. My only recommendation would be to post a picture with actual dimensions of the box for the rough opening and of the outside of the trim. It would help those on a tight a schedule who have to cut the whole before the product arrives. Otherwise great overall experience. I will be purchasing more of these in the future
