Estrich Schlag GmbH

What Estrich Schlag GmbH does

Estrich Schlag GmbH is a privately held, family-owned German screed and floor-construction contractor founded in 1981 by Günter Schlag and his wife Gaby, currently led by second-generation managing directors Michael Schlag and Gabriele Schlag. Headquartered in Föhren, Rheinland-Pfalz, the group operates across Germany and Luxembourg through its German HQ, the Luxembourg subsidiary Estrich Schlag S.à r.l. (Grevenmacher, 1997), and a new Wecker, Luxembourg office/warehouse under construction since 2024. With approximately 8 employees, the company is small in headcount but executes large-scale specialty floor projects for enterprise and government clients — including the European Court of Justice (12,000+ m² across three phases), Heidelberg Cement AG headquarters, Leica Camera AG (Leitz Park), Landesmuseum Bonn, and International School Differdange — alongside private residential work.

The company's product portfolio spans classic screeds (cement, optimized, accelerated, quick-setting, anhydrite, calcium-sulfate flowing), the proprietary VarietyFloor® branded line of exposed/terrazzo screeds (Estrichterrazzo, Sichtbetonoptik, Kornspitzen, Xtreme SP/PC), integrated floor components (impact and thermal insulation, ThermoWhite, moisture sealing, foam concrete, underfloor heating installation), and a flagship technology platform: the Estrich Revolution, billed as the world's first fully electric, fully automatic mobile mortar plant, capable of up to 6 hours of autonomous battery-powered on-site production with parallel charging. All screed mortars are produced in-house via wholly-owned subsidiaries Mörtel Mich GmbH (Germany, 2009) and Mörtel Mich S.à r.l. (Luxembourg, 2018), and the company operates fully automatic screed plants (first commissioned 2008) with proprietary on-site reloading technology for traceable, unlimited material output.

The business model is project-based B2B/B2C contracting: revenue is generated from one-time, quote-based floor construction engagements priced on area, complexity, and material specification. Sales motion is consultative and relationship-driven, combining on-site and online (video/email/phone) consultations with a single point of contact across the Beratung–Koordination–Ausführung (consultation–coordination–execution) process. Distribution is exclusively direct, on-site delivery using the company's own fleet and workforce across the DACH border region (Germany and Luxembourg). Quality is institutionalized through RAL Güteschutz certifications for both cement and calcium-sulfate screed, the Meisterhaft 5-Sterne rating (2025), and back-to-back TOP 100 Innovator awards in Germany (2019, 2022).
