Geocel: Setting the Standard in Sealants Since 1974

Geocel has been a fixture in professional construction, repair, and maintenance work for decades. Founded in 1974 and headquartered in Elkhart, Indiana, the brand built its reputation on one straightforward promise: that every product would perform when it matters most. That commitment quickly resonated with contractors and builders, and today Geocel is widely recognized as a market leader in roofing and construction sealants across commercial, residential, industrial, and transportation markets.

What separates Geocel from the pack isn't just product performance — it's a culture of quality and accountability. Geocel holds the distinction of being the first U.S.-based sealant manufacturer to earn ISO 9001 Registration, a benchmark that reflects the brand's unwavering focus on process, consistency, and customer confidence. Professionals rely on Geocel products to reduce costly callbacks, streamline labor, and deliver lasting results across the toughest application environments.

A Broad Product Lineup Built for Demanding Applications

Geocel's catalog spans a wide range of sealing and surface protection needs. At the heart of their lineup are caulks and sealants engineered to handle everything from joint sealing and weatherproofing to bonding dissimilar materials. Their tripolymer and polyurethane formulas are valued for their exceptional flexibility, UV resistance, and primerless adhesion on a wide variety of surfaces — metal, wood, concrete, vinyl, brick, and more. Whether you're sealing a roof flashing, finishing a trim joint, or waterproofing a structural seam, Geocel's sealant portfolio covers the task.

Beyond sealants, Geocel produces a line of specialty coatings and paints designed for surface restoration and long-term protection. These include silicone rubber roof coatings engineered to stand up to ponding water, reflective coatings for metal roofing systems, and surface primers that improve adhesion on challenging substrates. Geocel's UNIFLEX® product family, for example, offers rubberized silicone protection ideal for flat and low-slope roofing applications.

Rounding out the lineup, Geocel also offers RTV silicone solutions for high-performance sealing in demanding conditions. Products like the Geocel 8125 and 8150 100% silicone sealants deliver tight, flexible seals on non-porous surfaces including glass and metal, making them a go-to choice when silicone chemistry is the right call for the job.
