MORE INFORMATION ABOUT OUR PRODUCTS:

The Chemcurb system consists of a tough, 2-inch deep poured-rubber-seal into a surrounding curb which bonds to the roof surface (compatible with EPDM, PVC, BUR, coal tar, SBS modified, granulated APP, many types of coated metal and FRP). These easy to install systems are useful for retrofits and odd sized or difficult penetrations. They are recommended replacements for all pitch pan seals on new and re-roofs.

New MINICURBS enable cost effective sealing of small pipes and irregular or multiple penetrations such as HVAC conduit and drains, exterior lighting supports, surveillance cameras, mounts for solar panels and light angle-iron struts.

Curb components are made of pre-cast polyester composite or black structural urethane for saw cutting and can be configured to fit every shape and size of penetration! Product Datasheet on configuration and installation.

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. Available in Black, Gray, Limestone, and White.

1-Part Pourable Sealer is a moisture-cure self-leveling high performance sealer applied with a 1-quart caulking gun (available in re-sealable 2-liter pouches for larger jobs). It's designed for use in warranted ChemCurb penetration seals, and can be used in non-warranted metal pitch pans. Available in Gray only.

The Portals Plus pipe portals systems includes Alumi-Flash and are compatible with all types of roof systems. Due to the flexibility of the EPDM rubber caps, roof leaks are eliminated because penetrations are allowed to expand, contract, and vibrate independently of the waterproofing. Special retrofit caps are also available from  which accommodate a variety of pipes, tubes, and angle irons from .375" through 12". The caps are molded EPDM (Ethylene Propylene Diene Monomer) rubber which is compounded to resist degradation due to oxidation or exposure to ozone and ultraviolet rays, while having a serviceable temperature range of -60F to +270F. The caps are mechanically sealed to the Alumi-Flash base with a double "Weather-Tite Pressure Seal", which consists of two (2) beads formed into the collar that mate with the double grooves on the inside of the caps. Together, the Portals Plus cap and base provide a permanent, watertight and maintenance free means for penetrating roofs that is simple and easy to install.

Solar and A/C multi-pipe flashings in all sizes for all roof types.
