Family and company history in civil engineering NAJDER engineering® is a consulting company as well as a specialist contractor within civil and foundation engineering. We are preparing technical concepts, design projects, analyses and performing jobs as a subcontractor. Tomasz Najder joined in the period of 1974-1976 Skånska Cementgjuteriet (today Skanska AB) as a member of Supervising Team on the project “Second Dry Dock in Gdynia Shipyard”. 1983-2002 Tomasz Najder gained his experiences in Stabilator AB (daughter company in Skanska Group) as site manager, project manager and internal consultant (”trouble-shooter”), 1990-1995 as Production Manager (Stabilator AB- International Division in Poland),1995-2001 in Polish-Swedish company Stabilator Sp. z o.o. (Skanska Group) as Vice President and Executive Manager. Anna Elżbieta Najder (wife) owned 1991-2002 Polish company Polibeton Sp. o.o. and now Swedish Najder engineering® since 1997 (until 2005 operating as Polimark International) – operating globally. Anna Monika Najder (daughter) together with Tomasz Najder (as the President of the Board and Executive Manager) owned 2002-2009 Polish Najder engineering® operating in Poland. Family Najder is working within mining, tunneling and civil engineering since six generations. ready

Field of activity Foundation engineering and soil investigations. Reinforcement of existing foundations (underpinning) of industrial buildings, housing estates and ancient monuments (piling, anchors, injections). Tunneling, rock stability and soil improvement (deep mixing method, high/low-pressure injection, lime-cement columns). Stabilization of slopes and embankments (geogrids, soil reinforcement, drainage, geotextiles). Sealing of existing embankments, dams, dikes and waste deposits. Flood defense. Biological engineering, gabion constructions, coast protection. Leakage and moisture counteraction (insulations, drainages, sealing injections, dilatation repair) in concrete and brickworks structures. ready 3 3
