About us

'When you stop trying to be better, you stop being good.'

Founded in 1980 by Joachim Glatthaar as a family enterprise, Glatthaar Keller has grown to become one of the leading European firms in prefabricated basements. Within a team of 500 engineers, economists, project managers and highly qualified administrative, production and construction workers, we've successfully harboured an ethos of innovation and enthusiasm for everything we do. Our dedication and passion for producing the absolute best has lead to our continued success over the past 40 years.

Glatthaar Keller now has branches in Germany, Switzerland and England and also ships to the rest of Great Britain.

The benefits of prefabricated construction

Fast construction and a precision finish

Building plots can't always provide unlimited height and space, but there is always room for a basement. For us, there are virtually no geological restrictions that can prevent us from installing a basement. A Glatthaar Keller prefabricated basement has several advantages.  Individual elements are prefabricated in our factories under optimal conditions, regardless of the weather and according to precise specifications. This saves time and money, guarantees planning security and helps to avoid lengthy on-site construction.

Thanks to our high-quality prefabrication processes, a Glatthaar Keller prefabricated basement can usually be finished within a maximum of three to five days. Exact schedules will ultimately depend on specific customer requirements as well as the size of the basement.

Thanks to the production process using waterproof concrete, prefabricated basements offer the best possible protection against moisture penetration. Those wanting an extra level of protection can opt for the Glatthaar Keller patented Aqua Safe® waterproofing system.
