How well do the greens drain?
The green will be built either just slightly or, if preferred, significantly higher than the surrounding ground level, which will assist with drainage. In addition, very subtle drainage channels will be built into the contours of the putting surface, just as with real greens. After heavy rain, most of the water will percolate down through the synthetic turf fibres and infill, down to the turf backing. It will then run off according to the drainage contoured into the base. The green is able to drain water rapidly after heavy rain, which allows it to be playable all year long, regardless of the weather. The only exceptions are when the green is covered in snow or ice, or in frosty freezing conditions. Also, similarly to a natural grass green, temporary puddles may form in low spots during heavy downpours, but these will drain effectively after the rain subsides.
