What Rhiem & Sohn, Kies und Sand GmbH & Co.KG does

Rhiem & Sohn, Kies und Sand GmbH & Co.KG is a third-generation, family-owned Mittelstand company headquartered in Erftstadt-Erp, North Rhine-Westphalia, founded in 1946 and operating with approximately 180 employees. The company runs a vertically integrated construction-services and circular-materials platform spanning demolition, contaminated-site remediation, container service, earthworks, canal construction, and building-materials sales, supported by owned upstream assets — a gravel quarry, recycling plant, and DK 0/DK 1 landfill with operating permit valid through December 31, 2035.

The business model combines project-based B2B construction-services revenue (industrial, commercial, municipal) with high-volume, small-ticket materials and container revenue from private households, all within a roughly 150 km radius around Cologne Cathedral. Revenue mechanics are project-cyclical across demolition, remediation and civil works, with materials, recycling tipping fees and landfill volumes providing counter-cyclical ballast from the owned vertical-integration stack. Customer segments are described as B2B construction, municipal/infrastructure, and private households; no named enterprise anchor customers are disclosed.

The operating base is asset-heavy: the quarry, recycling plant and landfill are company-owned and certified under ISO 50001, DEKRA Entsorgungsfachbetrieb, SCC, RAL and IHK prequalification frameworks, supporting tender eligibility across institutional clients. Leadership comprises three managing directors — Robert Küsters (third-generation family principal), Manfred Schmacks and Alexander Fischer — and the company maintains an active apprenticeship pipeline with 12 trainees. Recent commercial signals include a 2021 Erftstadt flood response positioning, a 2025 employer-brand award sweep (TOP JOB, TOP Ausbildungsbetrieb, Familienfreundlicher Arbeitgeber), and the launch of TikTok and YouTube recruitment channels.
