Slijkerman

What Slijkerman does

Heibedrijf Bob Slijkerman is a family-owned pile driving and foundation construction company headquartered at Het Zwin 18 in Schagen, North Holland (Noord-Holland), Netherlands. Founded in 1999 by Bob Slijkerman after he apprenticed in his uncle's piling business alongside his father Cees, the company has operated continuously for several decades with father Cees still providing hands-on assistance on job sites. It is registered with KvK 55024610 as a private, founder-owned entity with no external investors or parent company. The business is small in scale, with approximately 5 employees including the founder, and serves customers exclusively within the Noord-Holland region.

The company delivers foundation solutions across five service lines: steel pipe piles (stalen buispalen), concrete piles (betonpalen), wooden piles (houten palen), sheet piles (damwanden), and specialized low-vibration pile driving (trillingsarm heiwerk) using compact equipment suited to hard-to-reach and vibration-sensitive locations. The firm holds VCA certification (Veiligheid, Gezondheid en Milieu) covering occupational safety, health, and environmental standards, which functions as a baseline credibility credential with construction-company buyers. There is no proprietary software, digital product, or technology platform — operations are conducted with physical piling machinery deployed at customer sites.

Revenue mechanics are entirely project-based and quote-driven, with no standard price list, no recurring contracts, and no subscription or retainer component. The go-to-market motion is direct-to-consumer in the literal sense: owner Bob personally visits prospective customers to discuss plans and assess the piling site, then delivers a custom quote. The customer base splits between private individuals (particulieren) needing residential foundations, renovations, or extensions, and construction companies (bouwbedrijven) requiring foundation piling for commercial or residential building projects. Marketing channels are minimal — primarily phone outreach and a basic website (heiwerkenfundatie.nl) — with no digital advertising, app presence, or partnership-based distribution.
