What Stienstra van der Wal B.V. does
Stienstra van der Wal B.V. is a third-generation, family-owned Dutch water construction contractor founded in 1958 and headquartered in IJlst, Friesland. The company designs, engineers, and executes water infrastructure projects including sheet piling, quay walls, docks, boardwalks, wooden bridges, mooring structures, trailer ramps, and construction pits, serving Dutch (semi-)government bodies, commercial enterprises, and private individuals. Its primary market is the three northern provinces of the Netherlands (Friesland, Groningen, Drenthe), though it has executed projects nationwide including for Royal Huisman in Zaandam and the Sluishuis residential complex in Amsterdam.
The company differentiates itself through a proprietary equipment line developed in-house under its GSV Projects brand, including the GSV 350 GREENLINE electric crane, the GSV 1800 PP pile presser, the GSV Hitachi 470 foundation machine, the GSV Sub-Anchor underwater anchoring system (capable of 50m depth), and a family of GSV Klapankers. These enable vibration-free and emission-free pile installation, a capability increasingly required for Dutch government tenders where CO2 Performance Ladder Level 3 certification (held since 2016), ISO 9001, VCA, SKH-FSC-COC, and VIHB certifications carry competitive weight.
Revenue is generated through project-based contracts, primarily Design & Construct engagements, with custom quotes per project. Customers engage directly via the company website, phone, or email; there are no intermediaries or resellers. The company operates a capital-intensive fleet (crawler and mobile cranes up to 50 tons, floating vessels, transport equipment) supported by two production locations (IJlst headquarters plus a Burgum prefab site opened in 2021), and employs approximately 35 professionals across the Stienstra and Van der Wal families' third generation.
