WWB Tiefbaugesellschaft

What WWB Tiefbaugesellschaft does

WWB Tiefbaugesellschaft mbH is a German mid-sized civil engineering contractor headquartered in Krunkel, Rhineland-Palatinate, founded in 1987 and relocated from its original Straßenhaus base to its current Industriepark 80 site in 1992. The company delivers a fully integrated portfolio of civil engineering services — earthworks (Erdbau), sewer/canal construction (Kanalbau), road construction (Straßenbau), site development (Erschließung), demolition (Abbruch), construction-waste recycling (Bauschutt & Recycling) via mobile crushing/screening, building materials sales (Baustofflager), and full-cycle project development (Projektentwicklung) from land acquisition through marketing of fiber-optic-equipped residential building plots. Operations are anchored by an in-house fleet of approximately 80 machines and vehicles (including 30-tonne excavators and mobile crushing plants), an owned earth-fill site (Erddeponie "Eintracht") of about 19 hectares with roughly 3 million tonnes of fill capacity in Ebernhahn, and digital project planning integrated with 3D machine control for execution, billing, and documentation.

WWB generates revenue primarily through project-based contracts awarded by municipalities and public-sector clients (its largest channel under Präqualifikation Bau § 6a VOB/A since 2017), large industrial enterprises, large-format retail chains (LEH-Discounter), and private individuals. Services are quoted on a project basis; no public price list exists. The company holds Gütezeichen Kanalbau (since 2001), AK 2 certification (2002), Entsorgungsfachbetrieb status under § 52 KrW/AbfG (since 2008), and CrefoZert creditworthiness certification. WWB operates regionally within the Westerwald / Rhineland-Palatinate area and has served as the anchor company of the TERRAS Tiefbau Gruppe — a network of mid-sized German civil-engineering specialists — since 2020.

Following a 2014 management buy-in by Ralf Sojka (joined in 2015 by Dr. Dirk Sojka), the company doubled revenue, integrated vertically via the 2022 acquisition of the Ebernhahn earth-fill site, and added capabilities including project development, building materials sales, and an energy and fuel park (Energie- und Brennstoffpark Krunkel). In 2024–2025 the management bench was further expanded with three additional managing directors (Andreas Harzer, Daniel Kaufmann, Oliver Schmidt). The company is family-owned, privately held, and employs approximately 80–85 staff including around 70 field workers.
