WDF Golf course bunker lining is a three-dimensional matting that is laid on the steep and complex shaped sides of bunkers and is designed to address the movement of sand in golf course bunkers. It works by trapping sand on steep bunker slopes to keep the playing surface intact and also acts as a filtration barrier limiting the migration of subsoil that could contaminate the bunker sand and make it unplayable.
Features:
- Strong and durable - Will not tear when bunker sand is raked
- Minimises sand contamination
- Minimises bunker face erosion
- Reduces sand thickness required
- Reduced maintenance required
- UV stabilised

The importance of sandpit mats for golf courses can be said to be the finishing touch, but there are many problems in choosing sandpit sand.
When choosing sand, the main considerations include color, shape, particle size, permeability, and surface cohesion.
1. Color: The color of the sand should be significantly different from that of the lawn. At present, white sand (mostly quartz sand), yellow sand (mainly river sand, some light yellow quartz sand), red sand, black sand, etc. are commonly used. The latter two types and other colors of sand are used less.
2. Appearance: Smooth or relatively smooth sand particles are difficult to combine and form resistance on the surface of the sand layer. Therefore, when the ball falls in, it is easy to hit a pit or even be buried. On the contrary, sand particles with surfaces that are not very smooth or have diamond corners will generate strong binding forces between them. Therefore, when the ball falls into the sand pit, it will face certain resistance and the possibility of being buried will be reduced.
3. Permeability: In order to prevent water accumulation in sand pits after irrigation or heavy rain, the permeability is required to be above 50cm/hour.
4. Surface collection force: Some sands have strong water holding capacity. After rain or irrigation, due to the action of water, the surface sand is prone to gather together to form a relatively hard shell, which affects the ball falling.
5. Particle size: In general, when a ball falls into a sand pit, it will have a significant impact on the sand. Therefore, if the sand is too fine, the ball will be buried directly. However, if the sand is too coarse, it will form a relatively hard surface, making it easy to hit the ball and lose the significance of the sand pit obstacle.
6. Stability: The stability of sand particle structure is important, but sand derived from limestone and carbonate has poor stability and is prone to chemical changes, making it unsuitable for use in sand pits. When selecting sand, relevant departments can be entrusted to identify its composition and determine the content of SO2.
Many courts require that the particle size of sand in the sand pit be the same as that of sand used on the green bed. The reason is simple: the sand pits around the green are often affected by strong winds and playing ball, and inevitably fly to the top of the green. If the sand is too fine, it will form a hierarchical structure in the local area of the green, affecting permeability; If the sand is too coarse, it will affect the quality of the green and lawn mowing operations.
In addition, due to the relatively fine sand in the sand pit, it is easily affected by external forces and moves. For example, the slope of a sand pit and the erosion of water after rain or irrigation can have a degree of impact on the movement of sand. So, many foreign stadiums have laid sand pit mats at the bottom of the sand pits, which not only prevent sand from moving but also greatly reduce the possibility of sand entering blind drainage ditches and drainage pipes. In the past two years, some stadiums have gradually used this material.
