What B.T. innovation does

B.T. innovation GmbH is a privately-held German specialty construction technology company founded in 1991 in Magdeburg, Sachsen-Anhalt, operating with a 51-100 employee headcount. The company supplies proprietary products and consulting services to the precast concrete industry and broader concrete construction sector, with an active customer base across more than 70 countries. Its portfolio is organized around three technology pillars: formwork and patented magnetic technology for rapid precast element production (including the Batterieschalung/Schmetterlingsschalung stationary production systems achieving up to 4x productivity), connection technology anchored by the BT-Spannschloss mechanical tension lock and the ThermoPin glass-fiber composite anchor for thermally decoupled sandwich walls, and a sealing/waterproofing family spanning InnoElast, SynkoElast, RubberElast, BasicElast, ProElast, LiquidElast, FlächenElast, MultiElast, and AgrarElast variants for joint and surface applications including pressurized water, agricultural biogas, and waterproof concrete (WU-Beton) construction.

The business operates a sales-led, multi-channel go-to-market combining direct B2B and B2C e-commerce (bt-baushop.de, b2c.bt-innovation.de), a dealer/partner portal (partners.bt-innovation.de), and direct sales via phone and email. Revenue is generated primarily through hardware sales of construction products and professional services consulting for the design and realization of resource-efficient precast production plants. The company is led by Managing Directors Felix von Limburg and Stefan Wittek, holds multiple DIBt general building approvals and European Technical Assessments (notably ETA 19/0013 for BT-Spannschloss with C2 dynamic-load classification and ETA 19/0498 for ThermoPin), and is part of the B.T. innovation Group alongside sister entities MAX-truder (precast plant engineering) and d2b-bygg (distribution and consulting). Recent operational signals include the 2025 publication of an Environmental Product Declaration for InnoElast Typ 2C, an updated BT-Spannschloss ETA, and accessibility compliance under the German BFSG.
