Floor Seal Technology

What Floor Seal Technology does

Floor Seal Technology, Inc. is a California-based, privately held specialty concrete contractor and product manufacturer founded in 1980 and headquartered in San Jose/Milpitas. The firm serves large general contractors, architects, healthcare operators, and corporate technology clients by providing a vertically integrated suite of concrete design, treatment, moisture control, and decorative finishing services for commercial and institutional building projects. Its primary customer work is sub-contracted on large new-construction builds, with named past projects including Apple Park (3,000,000 SF), Broadcom HQ, Facebook Burlingame Point, Google World HQ and Event Center, Netflix HQ, Uber HQ, Dropbox HQ, Intuit HQ, the New Stanford Hospital, and Stanford Children's Hospital.

The company's product portfolio centers on proprietary chemical and mix-design systems that it both sells and installs: VaporSeal 309 (a dissipating curing compound with a 15-year moisture-failure warranty, applied to more than 15M SF since 1998), the MirrorCrete polished concrete system for new and existing slabs, MirrorCure curing technology, MES 100 moisture-emission control meeting ASTM F3010, TekCrete ready-mix terrazzo (US Patent Pending) priced at roughly one-third of traditional terrazzo, TekFlor engineered cement topping, FloorCem SLU self-leveling underlayment, PowerPump rapid-installation equipment, and Color Match Patch invisible repair system. Installations are executed by factory-employed, licensed and bonded craftsmen rather than subcontractors, and the sales team consists of CSI-certified representatives who engage with architects and engineers during the specification phase.

Floor Seal Technology generates revenue through three primary streams: (1) sales of its proprietary concrete treatment products and consumables, (2) turnkey professional installation services delivered by factory-employed crews, and (3) technical consulting services including specification development, budgeting, moisture testing, flatness surveying, failure analysis, and LEED consulting. All pricing is custom and project-based, with centralized estimating out of the San Jose headquarters supporting nationwide quotes. The company is founder/management-owned, with CTO William R. Clyne as the named inventor behind its signature products and a leadership team that includes a VP of Operations, VP of Sales & Business Development, and an Architectural Director.
