ChemCurb® Penetration Seal ComponentsSKU:

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 7.5 or 5 inches. Straight pieces are available in 6 and 12 inch lengths and combined with 2-inch radius corners to create larger sizes. The outer surface is impervious to ice, corrosion, UV (ultraviolet) light, and ponding water.


Bonding surfaces should be clean, dry and free from all contamination that may inhibit the sealant’s performance. Remove all previously applied caulk, mastic, cement, asphalt, and other contaminants from penetrations with a wire brush. Brush away all gravel or loose granules. Isopropyl alcohol is an effective cleaner for surface preparation. Please contact customer service for application guidelines with temperatures below 32°F (0°C). Do not use on TPO without the use of TPO primer. Do not use on Hypalon. Smooth APP membranes require a granulated target. This product sets rapidly upon exposure to moisture. Please refer to data sheet for step-by-step installation guidelines.
