What Zoontjens does

Zoontjens International B.V., headquartered in Tilburg, Netherlands, is a 120-year-old Dutch specialist contractor and subsidiary of CRH that designs, manufactures, and installs proprietary flat-roof systems. The company's portfolio centers on five system categories: roof paving (Dakbestrating), parking roofs (Parkeerdaken, via the Pardak 110 system), retention roofs (Retentiedaken) for sustainable urban water management, gallery and balcony elevation (Galerij- en balkonophoging, via the Dreen family of systems including Combiplus, CeramicaPlus, and Nxt), and fall protection (Valbeveiliging, via the BiboBlock system). All systems are self-developed and self-applied, with differentiated technical features including non-penetrating fall protection installation, load-bearing rooftop parking tile systems, and dry-installation adjustable supports for accessibility-focused gallery renovations in social housing.

Zoontjens sells exclusively business-to-business through direct account management to general construction contractors, specialist contractors, housing corporations (woningcorporaties), property developers, and architectural firms. Pricing is project-based and custom, supported by an online calculation tool (calculatietool) and specification service (bestekservice) used by architects and contractors during design. Distribution spans seven European countries (Netherlands, Belgium, France, Germany, Austria, United Kingdom, Italy) via localized websites, with the Dutch market headquartered at Tilburg. The company operates a sister-company relationship with Struyk Verwo Infra (also under CRH) to refer ground-level paving work, enabling a complementary roof-to-ground surface offering.

The company's growth is anchored by structural European drivers: aging-population accessibility retrofits in social housing stock, urban densification driving rooftop parking demand, and circular-construction renovation mandates. CRH ownership provides capital backing and continental distribution leverage without disclosed revenue figures. Leadership is anchored by Managing Director Paul Heerkens, with sales and technical teams handling specification-driven project work across the European footprint. The business model is fundamentally hardware-and-installation rather than software-driven, with proprietary physical systems (Dreen, Pardak, BiboBlock) and decades of project references constituting the core competitive asset.
