COLOGNE, GERMANY, DECEMBER 8, 2021 – Germany’s largest Capillary Bunkers installation so far has just been completed at the Marienburger Golf Club in Cologne, by architect Christian Althaus and contractor Sommerfeld.

Founded as Cologne Golf Club in 1906, the club moved to its current site in Marienburg in 1909. The construction of an autobahn (motorway) to Aachen in the thirties saw the course reduced to nine holes, which it has remained ever since. The club called in architect Althaus to advise on course improvements several years ago, and in 2021, the upgrade project got underway, incoporating the reconstruction of all nine greens – which were not properly drained – as well as bunkers, and the regrading of fairways to provide better drainage and more interest.

“The course is within a kilometre of the Rhine River, and is thus partially sandy, but even so it was clear that we needed a bunker liner,” says Althaus. “Even on the parts of the site that have a sand base, the steep faces of the bunkers would erode quite badly without it, and also the sand of the sub-base and the bunker sand would intermingle and contaminate the bunkers.”

Althaus considered various liner options, but was led to select Capillary Bunkers on environmental grounds. “We considered various liner options, but I knew I needed a very strong and stable liner on environmental ground, which led us to choose Capillary Bunkers,” he explains. “The strength and neutrality of the Capillary Bunkers product made it the right choice.”

Construction work is complete, and the project is growing in – the course will reopen in spring 2022.



1. At the core of our solution, Capillary Bunkers is a patented and engineered polymer-based concrete. It is the only building material that can rapidly drain water while also moving water up. Capillary Bunkers’ cutting-edge, patented technology helps you control water in any climate, season, and soil type, providing better, more consistent playing experiences while reducing costs.

2. Capillary Bunkers is recognized as the world’s leading and most advanced bunker liner, and the most durable bunker construction method. It allows water to flow through the base of the bunker while keeping sand on the faces and preventing washouts, keeping bunkers in perfect shape during any weather condition. Over 800 courses around the world have built or renovated their bunkers with Capillary Concrete, including dozens of golf’s top 100 courses.
