LymTal International

What LymTal International does

LymTal International, Inc. is a privately held US manufacturer of specialty polymer waterproofing and concrete-protection systems, founded in 1994 in Lake Orion, Michigan by Frank Lymburner and Magdy Talaat, both former senior executives of Harry S. Peterson Co. (HSP). In its founding year, LymTal acquired HSP's manufacturing, research, and warehouse facilities and absorbed its experienced workforce, giving the company a combined 50+ years of polymer technology expertise inherited from HSP's 1929 origins. The company operates four divisions — Commercial Waterproofing, Bridge & Transit, Roofing, and Toll Manufacturing — under the registered Iso-Flex brand.

The core product line centers on polyurethane- and epoxy-based membrane coatings, joint sealants, expansion joint systems, flexible grouts and headers, concrete penetrating sealers, and roofing membranes. Products are engineered for demanding infrastructure environments including parking decks, stadiums, plazas, bridges, transit facilities, and roofing substrates, with systems engineered for moisture and chloride-intrusion protection, traffic-bearing loads, UV exposure, and seismic or thermal movement. The product portfolio includes specialized systems such as low-VOC membrane coatings (Iso-Flex 760), ADA-compliant metal cover plates (CapSpan), seismic-rated expansion joints (Xtreme), and 100% silane penetrating sealers (Iso-Flex 618 series). Manufacturing takes place in a 50,000 sq ft controlled-environment facility in Michigan.

LymTal generates revenue through three streams: branded Iso-Flex product sales (membrane coatings, sealants, expansion joints, sealers, roofing membranes) sold directly via a network of US regional sales offices; toll manufacturing and toll packaging of specialty polymers for customers lacking in-house capacity; and private-label/custom new product development. The go-to-market is enterprise field sales targeting engineers, owners, and contractors in commercial construction, bridge/highway, and transit markets, with procurement gated by specification approvals and qualified product lists maintained by state and local authorities. Customer references include The Hartford Corp. Parking Garage, Novartis Headquarters Parking Garage, and the Lincoln Reflecting Pool restoration (2011–2012). Pricing is not publicly disclosed and is handled through direct sales engagement.
