SealGuard

What SealGuard does

SealGuard Inc. is a privately held Pennsylvania-based manufacturer founded in 2004 that produces proprietary hydrophobic polyurethane grout formulations for water control, sealing, and adhesion applications in concrete and underground structures. The company operates as a subsidiary of Sub-Technical Inc., a grouting contractor that developed and field-tested SealGuard's products across 900+ water control projects spanning 15 years. Its core product line consists of three formulations: SealGuard II, a dual-component fast-reacting grout (1–3 second reaction time) for high-flow leaks exceeding 50 gallons per minute; HyperFlex, a single-component pre-catalyzed grout with 30–60 second reaction time and NSF-ANSI-CAN-61 potable water certification; and X-Seal, a single-component sealant/adhesive for precast concrete sections, also NSF-61 certified.

SealGuard monetizes through direct e-commerce sales of grout products, accessories (caulking guns, static mixers with patented check valves, mechanical injection packers, drill bits), and starter kits, with unit prices ranging from approximately $18 for drill bits to $650 for SealGuard II multi-packs. The company serves five verticals: wastewater/municipal infrastructure, mining, civil engineering, commercial/residential construction, and precast concrete manufacturers. Distribution combines direct-to-consumer online sales and phone/email orders in the US with two regional distributors (Fernco Inc. in Canada and S1E Limited in the UK/Europe). The company maintains ISO 9001:2015 certification through 2026 and holds patents on a check-valve mixer (US, Europe, Australia/New Zealand) and on Karstic terrain grouting methods (US, October 2010).

The business runs with 1–10 employees under a hybrid go-to-market: direct-to-consumer e-commerce supported by content-rich technical documentation and SEO, paired with a sales-led motion in which in-house engineering, chemistry, and geology staff (120+ years of combined experience) provide personalized project specification support. Specialized equipment such as pumps is not publicly priced and requires direct consultation. Leadership includes Eric Smith as President; the firm is family-owned with no disclosed institutional investors or external funding.
