İMG at a Glance

An Engineering-Led Approach to Waterproofing

İMG Yapı Yalıtım Mühendislik A.Ş. was founded in 2006 by civil engineer E. Mahmut Gürün as a sole proprietorship and restructured as a joint-stock company in 2015. Over almost 20 years the company has completed more than 1,000 waterproofing projects.

Our expertise spans a wide range of structural waterproofing; over the past decade, however, we have specialised in basement waterproofing and damp-proofing, becoming one of Türkiye's few dedicated specialists in this field. Alongside application work, we also provide waterproofing consultancy to private-sector and public-sector clients.

Our Story

The Journey from 2006 to Today

2006 — The Beginning

Civil engineer E. Mahmut Gürün founded İMG as a sole proprietorship, with the aim of bringing an engineering-led approach to waterproofing. The early years were spent combining traditional waterproofing methods with hands-on site experience.

2010–2015 — Specialising in Negative-Side Waterproofing

During this period we specialised in no-dig, negative-side (internal) waterproofing and acrylate gel injection. We were among the first companies in Türkiye to apply acrylate gel injection from the negative side. In 2015 we completed our corporate restructuring as İMG Yapı Yalıtım Mühendislik A.Ş.

2015–2020 — Manufacturing Under Our Own Brand

By bringing together the needs we encountered on site and our own laboratory work, we established the Dryvatec brand. Crystalline waterproofing materials, acrylate gel injection products and original solutions such as the Nem Kutusu damp control unit began to be manufactured under the Dryvatec name.

2020–Today — Focus on Basements and Damp

Over the past five years we have deepened our expertise in basement waterproofing and damp treatment. From our Istanbul and Izmir offices we complete hundreds of projects a year, while also providing independent waterproofing consultancy to private-sector and public-sector clients.
