Who we are and what we do
We are golf course superintendents and greenkeepers. We understand the challenges and what it takes to maintain a great golf course. Everything we have developed gets tested on the golf course, in real-life situations, over and over again, and we work with some of the most advanced laboratories in the world to develop the best and most effective solutions to everyday challenges.
Capillary Concrete™ bunkers were first installed in 2010 in Scandinavia in a very tough climate with severe winter ground freezing conditions. The product was invented and developed by Founder Martin Sternberg, CGCS, as a means of finally resolving all bunker problems in even the most severe golf course locations. Today, thousands of bunkers have been built or renovated with Capillary Concrete all across the world, from Australia, Japan, Africa to the USA and Europe. Capillary Concrete is available throughout the world, in every major golf market through local distributors.
Capillary Concrete is an international company and is owned in part by Martin Sternberg and Annika Sörenstam, among others. The Board of Directors is made up of some very experienced turf professionals, including Stig Persson, former Chairman of the Swedish Greenkeepers Association, FEGGA (European Greenkeepers Assoc.); and Martin Sternberg, CGCS. We also are fortunate to have a very competent administrative team in offices in Celebration, Florida.

Annika is the greatest female golfer of her generation, and often regarded as the best of all time. During her 15-year Hall of Fame career, she rewrote the LPGA and Ladies European Tour (LET) record books, won countless awards, and changed the way women’s golf was played, viewed and covered. She amassed 89 worldwide victories, including 72 on the LPGA, 10 of which are Major Championships. Her record-breaking achievements include eight Rolex Player of the Year awards, six Vare Trophies (recognizing the year’s lowest scoring average, including one for the lowest ever recorded, 68,6969 in 2004), and is the only female to break 60 in an official event. This feat earned her the nickname, “Ms. 59.”
Annika stepped away from competitive golf at the end of the 2008 season to further establish the ANNIKA brand of businesses, including ANNIKA Course Design. Throughout her many successes on and off the course, Annika remains determined to bring women’s golf and sports to the mainstream.
