Kamphuis Sloopwerken en Asbestsanering

What Kamphuis Sloopwerken en Asbestsanering does

Kamphuis Sloopwerken en Asbestsanering B.V. is a family-owned Dutch demolition and hazardous-materials remediation company founded by Gerard Kamphuis in 1953 and headquartered in Reutum, Overijssel. It operates three locations (Reutum, Tubbergen and Enschede) and serves contractors, housing corporations, municipal and national government bodies, real-estate developers and private individuals, primarily in the Twente region and eastern Netherlands. Core services are total and renovation demolition, certified asbestos abatement (Procescertificaat Asbestverwijdering, held since 1997), and BRL7000-certified soil remediation, typically delivered as integrated project-based contracts.

The company's central technical and brand asset is its proprietary "Omgekeerd Bouwen" (Reverse Building) circular demolition methodology, a three-phase process that inventories materials pre-demolition, runs a "Waardescan" valuation, and routes recovered items into reuse, recycling, or resale. Recovered materials are monetised through a physical marketplace in Tubbergen, an online presence on Marktplaats, a Shop-in-Shop at Kringloopbedrijf de Beurs, and a premium design-furniture sub-brand (Omgekeerd Bouwen Design) sold exclusively via Studio Damhuis. Internal capabilities are supported by an in-house equipment fleet that includes a Volvo EC250E 25-ton excavator and a Wacker Neuson EZ17e fully electric mini-excavator.

The business model is project-based quoting with multi-year contracts and custom pricing (no published tiers); revenue streams are demolition services, asbestos abatement, soil remediation, and transactional sales of reclaimed materials. Notable enterprise and public-sector engagements include the Rijksoverheid's Herman Gorter Complex Utrecht (251,500 kg CO2 saved, 37,000 m² inventoried), Stadhuis Almelo (2020–2021), the Zuiderspoorflat Enschede for housing corporation Domijn (2018), Alliander Arnhem (95% recycling rate), and Thales Hengelo. The company carries ISO 9001:2015, VCA**, SVMS-007, SCL Trede 3 and PSO Prestatieladder Trede 3 certifications and received the Ondernemersprijs Gemeente Tubbergen in 2019. As of September 2026, Kamphuis is acquiring the employees and part of the equipment of Ardesch Sloopwerken in Kloosterhaar.
