Revettment - more appropriate to links golf
no longer available. It is important to appreciate that the quality of playing surface will vary depending on moisture retained in the sand, and playing characteristics will also change between winter and summer. I believe that there is no perfect sand which plays consistently under both wet and dry conditions. It was interesting to note that pop-up irrigation heads have been placed in the bunkers at Wisley Golf Club and Carnoustie in order to try and achieve a level of consistency. This really is taking the concept of bunker management to its ultimate. I also believe that, where new bunkers
are constructed, the new sand must have time to ‘bed-in’, i.e. settle and weather, in order to produce the desired playing surface.
As a point of reference, I visited a golf club a few years ago where they had
Traditional sand face. Three turf revett may work
embarked on a bunker reconstruction programme. Three years into the programme, members were beginning to question the quality of playing surface which, in some cases, was very good, in some, somewhat indifferent and, in others, rather poor.
Having analysed each bunker in turn, it was clear that the quality of the playing surface varied with age of construction. Those bunkers constructed within the previous twelve month period were considered rather poor, the sand being loose and fluffy. Those bunkers which were mediocre were aged between twelve and eighteen months, and those bunkers which were thought to have a good playing surface were eighteen months plus or the original bunkers which had a firm base.
Golfers must, therefore, be patient with the restoration programme being
undertaken. In an ideal world, a bunker renovation programme would be carried out within a two to three year period to try and maintain a level of consistency.
Maintenance
Having selected the right bunker sand, and allowed the material ample opportunity to bed in and weather, the most significant factor affecting the quality of playing surface is that of maintenance. Depending on the sand selected, the bunker sand should be placed no more than a consistent 100mm firmed depth over the whole bunker floor. Where a sand face is provided, the sand on the face itself should not exceed 50mm. The ideal playing surface provides a sand which is slightly moist and well firmed, but with the immediate 25mm of surface raked-over into which the ball will sit.
