ChemLink ChemCurb Box Components
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 that, 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 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 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)
In addition to these ChemCurb Box Components, you will need these other components to complete your
ChemCurb System:
-
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.
