What Maru does

Maru is a privately held Estonian construction and manufacturing conglomerate founded in 1991 and headquartered in Tallinn, operating across seven wholly owned subsidiaries: Maru Ehitus AS (general contracting, project management, building design, real estate development), Maru Metall AS (steel structure manufacturing), Maru THM OÜ (assembly and installation), Maru Betoonitööd OÜ (concrete works), Moodul AS (mechanical-engineering and construction steel frames, 9,000 m² facility in Valga), MDSC Systems OÜ (mobile defense and modular solutions under the Maru Defence and Rolling Unit brands), and Maru Rakennus Oy (Finnish general-contracting subsidiary). The group is 100% Estonian-owned, employs more than 400 specialists, and reported €100M turnover in the most recent financial year. Production technology includes laser, plasma, and flame cutting; CNC machining; MIG/MAG, TIG, and robotic welding; and in-house engineering for custom PVC hangars and hybrid hangar configurations engineered for local snow and wind loads; the company states it has built Estonia's longest halls with the widest spans.

Revenue is generated through project-based, quote-driven contracts across seven streams: general construction and contracting, steel structure manufacturing, PVC hangar design-supply-install, specialized concrete works, assembly and installation services, mobile solutions (defense field hospitals, modular shelters), and real estate development via business parks such as Raku Business Park. Pricing is custom per project with no public price list, bid through tenders and direct enterprise sales. Primary customer segments are defense (notably a seven-year, up-to-€150M framework with the Estonian Centre for Defence Investments), energy/utilities (Utilitas zero-emission heat plant), logistics and food distribution (Restate Jüri / Fruit Xpress, Bidfood, VBH Estonia, Lennuradari Laod), commercial and industrial developers, and international government buyers (Uruguay Police, US Department of Agriculture). Distribution is direct enterprise sales led by named sales and project managers (Rauno Lõhmus, Raido Pärna, Madis Laiverik), with no retail or consumer channel. Key certifications include ISO 9001/14001/45001, NATO AQAP, EN 1090-1, and EN ISO 3834-2 across relevant subsidiaries, plus Estonian Economic Activities Register permits covering general construction, bridges/roads, building audits, fire safety, electrical work, and heritage protection.
