Sandersfire International

What Sandersfire International does

Sandersfire International is a UK-based manufacturer of fire-stopping mortars, operating as a division of Hoben International Limited, which is in turn a wholly-owned subsidiary of AIM-listed Goodwin PLC. The company produces two products under the Firecrete brand: Firecrete EN STD, a standard-grade mortar for general sealing of wall and floor penetrations around cabling, pipework, and fire dampers, and Firecrete EN HS, a high-strength variant for large span floor openings and unsupported fire dampers. Both products are dry-blended from gypsum plasters, graded fire-resisting aggregates, and additives; when mixed with water and trowelled or poured into penetrations, the controlled-expansion chemistry develops compressive membrane action that provides load-bearing capability without steel reinforcement in most floor applications. The portfolio is non-shrinking, gas-tight, sets within 2–3 hours, and achieves 240-minute fire integrity ratings and 4-hour ASTM Fire and Hose Stream test performance (EN HS).

The business model is direct B2B: a UK-based sales team responds to specification-driven inquiries from construction firms, building services contractors, and infrastructure projects (including London Underground), with pricing not publicly disclosed and quotes provided on direct inquiry. Customers are segmented vertically into Construction and Building Services (general wall and floor penetration sealing) and Infrastructure and Commercial Buildings (large spans, fire dampers, transit infrastructure), with marketing executed through the company website's product pages, technical data sheets, and downloadable certification documents. Revenue, headcount, and unit volumes are not publicly disclosed, and the company has no external fundraising, no API or software products, and operates entirely in physical building materials.

Distribution is regional (confirmed UK) with a stated European brand leadership position, and the company's competitive position is anchored in a broad certification stack: CE marked (EN 1366-3), UL Listed (XHHW7) across multiple through-penetration firestop system numbers, LUL approved, and ISO 9001:2015, 14001:2015, and 45001:2015 certified. The Firecrete and Sandersfire brands are registered trademarks. There are no named end-customer logos, no disclosed M&A or partnership-driven expansion events, and no evidence of recent geographic or product-line expansion beyond the established two-SKU range.

Core offering

Sandersfire International manufactures a comprehensive range of high-quality fire-stopping mortars under the Firecrete brand, supplied as dry-blended powders mixed with water and trowelled or poured into wall and floor penetrations to create non-shrinking, gas-tight seals that prevent the passage of flame, smoke and toxic gases. The portfolio comprises two SKUs: Firecrete EN STD for general sealing of cable and pipe penetrations, and Firecrete EN HS for high-strength, load-bearing applications such as large floor openings and unsupported fire dampers.

Product overview

Sandersfire International manufactures a unique and comprehensive range of high quality fire-stopping mortars under the 'Firecrete' trade name. The product portfolio consists of two mortar products: Firecrete EN STD (standard grade for general sealing applications in wall and floor penetrations for cabling and pipework) and Firecrete EN HS (high-strength grade for large span floor openings and unsupported fire dampers). Both products are dry-blended from gypsum plasters, natural and processed fire-resisting aggregates, and additives. They are mixed with water and trowelled or poured into penetrations to create non-shrinking, gas-tight seals that stop passage of flame, smoke and toxic gases.
