Stump-BTE AG

What Stump-BTE AG does

Stump-BTE AG (legal entity: Stump-BTE Bautechnik AG) is a Switzerland-based specialty civil engineering contractor providing groundwater management, drilling, and well services to construction companies, infrastructure developers, public sector entities (cantons, municipalities, federal agencies), and industrial clients. The company operates as a subsidiary within Marti Group, a Swiss family-owned construction conglomerate of approximately 80 group companies, and runs its headquarters in Solothurn (Bielstrasse 102) plus an Austrian subsidiary (Stump-BTE Bautechnik GmbH) in Graz. Reference clients include SBB, ETH Zürich, armasuisse, BKW Energie, Illwerke vkw, Bosch, Migros Zürich, Cargo sous terrain, and international clients such as the General Directorate of State Hydraulic Works of Türkiye.

The company's service portfolio spans three integrated lines: drilling (core, precision/pendulum, destructive, and deep drilling up to 2,500 meters using multifunctional directional rigs); ground and slope water management (wellpoint systems, filter wells up to 500mm, open dewatering with pumping capacity of 500–20,000 liters/minute, siphon and electro-pneumatic drainage systems, and mobile construction site wastewater neutralization plants); and well service (inspection, maintenance, video camera inspection, regeneration, and rehabilitation of water-supply, monitoring, and heat-pump wells). Differentiating technologies include a proprietary precision drilling and correction method guaranteeing ±8mm deviation (used for dam pendulum and structural monitoring installations), wire-line core drilling systems, and energy-free siphon drainage architectures.

The business model is project-based and sold through enterprise field sales. Contracts are won via direct tendering and negotiated client relationships, with project values ranging from CHF 0.02 million to CHF 2.7 million. Customers are reached through a multilingual corporate website, trade publication features, social media (LinkedIn, Instagram, YouTube, XING), and an extensive public reference project portfolio; the parent Marti Group provides institutional visibility and cross-referrals. Technical cooperation with pigadi GmbH (Germany) supplements well rehabilitation capabilities, and Alwatec AG handles referrals for demanding wastewater treatment work. Pricing is not publicly disclosed and is tailored to project scope, site conditions, and technical specifications.
