What SER Group does

SER Group (legally SER Sanierung im Erd- und Rückbau GmbH) is an integrated demolition, earthworks, contaminated-land remediation, and construction-waste recycling company headquartered in Heilbronn, Germany. Founded in 1995 and acquired by Heidelberg Materials AG in February 2023, the company operates three modern recycling locations in the Heilbronn metropolitan area and delivers services nationally across Germany to general contractors, real-estate developers, architects, municipalities, hospitals, and industrial decommissioning clients. Its core offerings span building and industrial demolition, large-scale excavation and earthworks, hazardous-material remediation (PN-98 compliant), and processing of mineral demolition waste into certified recycled construction aggregates (RC products), rail track ballast, and mining backfill — alongside the proprietary varioWand modular landscape system and Biosphärenstein wildlife-habitat product.

The company's technology base combines heavy specialized equipment (a 100-tonne Liebherr R 960 long-reach excavator with up to 33 m working height, a CAT 336F L XE hybrid excavator delivering up to 25% fuel savings, and 3D-machine-controlled excavators and dozers) with proprietary processing infrastructure including a rail-connected Gleisschotterwaschanlage (rail track ballast washing plant), three RC aggregate production sites, and a concrete filling station at Lichtenbergerstraße. Certifications supporting its market position include PQ VOB prequalification for public procurement, RAL GZ 501 for recycled aggregates, ISO 50001 energy management, EFB (Entsorgungsfachbetrieb), DGNB membership, and SQMS quality and safety management — collectively qualifying SER for regulated public-sector and infrastructure tenders.

SER monetizes primarily through project-based professional services contracts (demolition, earthworks, remediation) and hardware sales of recycled aggregates and varioWand products; pricing is quote-driven with no public price list. The company's go-to-market is enterprise field sales via competitive tenders, referrals, and direct outreach, with limited digital tooling (an online Abbruchkalkulator demolition calculator and a webshop). Customer segments span retail chains (Bauhaus, Edeka, REWE, C&A), healthcare (Klinikum am Gesundbrunnen), public infrastructure (Hafenbahnbrücke Heilbronn, Deutsche Bahn rail ballast contracts), and industrial decommissioning (Hansa-Areal Stuttgart). As a Heidelberg Materials subsidiary, SER now sits inside a global building materials platform pursuing 50% circular-content concrete production by 2030.

Core offering

SER Group is an integrated contractor performing building and industrial demolition, earthworks, and contaminated land remediation across Germany, with three modern recycling locations in Heilbronn processing demolition material into certified recycled construction aggregates (RC materials) for resale into the building supply chain. It also manufactures and sells the varioWand modular landscape wall system and Biosphärenstein wildlife habitat stones made from its own recycled hard rock, plus specialised rail track ballast washing and mining backfill services.

Product overview

SER Group operates as an integrated demolition, remediation, and earthworks company with a portfolio of specialized services and products. Core services include demolition (Rückbau), remediation/sanitation (Sanierung), earthworks (Erdbau), earth filling, path construction, rail track ballast processing, and mining backfill. The product portfolio centers on the varioSystem, which includes the varioWand modular landscape element and Biosphärenstein wildlife habitat stones—both manufactured from recycled materials. The company also produces recycled construction aggregates (RC-Produkte) at three modern recycling locations. Digital offerings include an online demolition calculator. All operations are aligned under a circular economy strategy, with the company being a market leader in the Heilbronn region and part of Heidelberg Materials AG since 2023.

Direct peers

• Hagedorn Unternehmensgruppe: One of the largest integrated demolition, remediation, and recycling groups in Germany, with a national yard network and similar focus on construction-waste recovery. Highly comparable to SER's demolition-plus-recycling model and a likely competitor on regional German tenders.
• Eggersmann Gruppe: German family-owned group combining demolition, earthworks, container services, and materials recovery — the same integrated service stack SER operates in the Heilbronn region. Directly comparable for benchmark on integrated recycling utilization and circular-economy branding.
• Bauer AG: German-based international specialist foundation engineering group with adjacent demolition, remediation, and materials-recycling business (Bauer Resources). Comparable on specialized civil-engineering site works, contaminated soil handling, and recycling of construction-derived materials.
• Wiegel GmbH: Mid-sized German demolition and environmental-services firm with railway, asbestos, and contaminated-site remediation lines similar to SER's HAZMAT remediation and rail ballast washing offerings. Comparable competitor on specialized remediation tenders.

Broad incumbents

• Holcim Group: Global building materials and aggregates major with growing circular-construction and demolition-waste recycling activities in Europe. Comparable as a broader incumbent setting national strategy for low-carbon and recycled aggregates that influences SER's competitive context.
• Heidelberg Materials AG: DAX-listed global building materials group and SER's parent since February 2023. Operates aggregates, cement, and ready-mix concrete across Europe — the broader incumbent driving SER's circular-economy integration and the natural benchmark for parent-level scale and strategy.
• PORR AG: Austrian construction group with demolition, environmental engineering, and recycling activities across DACH. Comparable as a broader-incumbent competitor on integrated demolition and remediation tenders, particularly in southern Germany and Austria.
• Implenia AG: Swiss-based construction and real-estate services group with integrated demolition, civil engineering, and infrastructure-recycling offerings across the DACH region. Comparable as a broader incumbent that competes on large demolition and remediation tenders in German-speaking markets.
• STRABAG SE: European construction group with significant demolition, earthworks, and materials-recycling capabilities via subsidiaries such as Züblin and Stump. Comparable as a larger, diversified incumbent that competes on integrated demolition and civil engineering projects in DACH.
• Remondis SE & Co. KG: Germany's largest privately held recycling, waste-management, and environmental-services company with nationwide infrastructure for construction waste, hazardous materials, and mineral recovery. Sets the broader-incumbent benchmark for materials-recovery scale and regulatory positioning.
