The grains in the Bunker Sand are crucial. Both for uniform competition conditions and for the maintenance of the entire golf course.
Dansand® Bunker Sand is manufactured to comply with the recommendations of the United States Greenkeeper Association – USGA – (refer to topdressing and root zone mix as well). If the grains of sand are larger than 2 mm there is a risk of sand being thrown up onto the green damaging the mower. Bunker sand from Dansand A/S ensures the best and most uniform playing conditions in all kinds of weather - and avoids extra costs and damaged blades for the golf club.
Building the perfect bunker is a demanding process - we assist with our expertise and give advice based on experience from the US.
Bunkers are firm with a very thin layer of loose sand - you have to remember that when renovating. Firstly al loose sand is removed, then a check is done to see if the bottom has a sand layer that can be compressed into a firm surface without the sand loosing its draining ability – compressing must not result in a lake being formed when it rains or through watering. The sand layer must have a thickness of 20 – 30 cm and be compressed with a roller, punner or mini tractor. If the base has become too deep or the slope too steep from removing excess sand you can change the slope by compressing more sand into the bunker. Water the sand thoroughly before rolling to ensure proper sand compression. When this is done, the sand bottom is lightly raked and 5 – 7 cm Dansand® Bunker Sand in grain size 0.1 – 1.0 mm is added.
You now have a bunker that may be a punishing obstacle, but where the player possessing adequate technique can still make it out of there - without the ball disappearing into the sand. When the bold lands vertically into a properly constructed bunker it forms a 'fried egg', but does not disappear.
A bunker like that is easier to maintain on a daily basis and the volume of sand being thrown up onto the green will be reduced significantly.
