Capillary Concrete Solves Landfill Drainage Problem

Dallas, United States: Kasey Kauff, Director of Grounds at the new Trinity Forest course near downtown Dallas, had a problem. The course – designed and built by Bill Coore and Ben Crenshaw and intended from its earliest conception as a venue for major golfing events – is built on an old capped landfill.
It was the use of such a site that made it possible to build golf in such close proximity to a big city, and it was the waving contours of the created ground that got Coore and Crenshaw interested. But building on a landfill forces many compromises.
“The landfill is capped with clay, which was designed not to allow water to penetrate, and which we are not allowed to cut into at all,” said Kauff. “That’s why the course has no trees – the roots would penetrate the cap – or water features. The whole golf course was built with fill placed on top of the cap.
“The bunker bases are at grade level, and below them is the cap. This became a major problem for us: the impermeable clay cap stopped the bunkers from draining, and after any significant rains, we had waterlogged bunkers. But we couldn’t drain them in the normal way, because we are not allowed to go into the cap.”
After a visit from Ted Fist of Capillary Concrete, Kauff realised that the product offered him a solution to his issues. “Although we cannot put traditional drains under the bunkers, we are able to put flat tile on the base of the bunkers – in other words, right on top of the cap – and then lay Capillary Concrete on top of that. We can’t lower the bunker floor, so that does mean players are standing fractionally higher in the bunker than before, but that doesn’t really make any difference,” he said.
Capillary Concrete’s American team, along with Mark Creighton of Ewing Irrigation, its US distributor, came to Dallas and trained Kauff’s crew how to install the product. Since then the project has been entirely internal. “The ability to do it ourselves was what made Capillary Concrete especially attractive to me,” he said. “It meant I could do it when I wanted, not on someone else’s schedule. If it rains, and we can’t install, that doesn’t matter, we do something else that day. If we had a contractor, we’d be paying for downtime.”
Thirty of the course’s 80 bunkers have already had Capillary Concrete installed, and Kauff reports good results. He said: “We had an inch and a half of rain recently. One of the bunkers we did last year has a severely steep face, but there was no washout at all.”
