In general, the rate at which water moves through a soil, otherwise known as the perk rate, is relatively slow and quite variable between different types of soil. These rates may range from a few inches per hour for sandier soils to only a few hundredths of an inch per hour for higher clay content soils — such as those commonly found on skinned infields.
One of the most effective ways to ensure that your infield will be playable after a heavy rain is to maintain a proper grade on the field to allow for positive surface drainage. Directing water across skinned areas as opposed to letting it percolate down through them will significantly improve how your field handles water. It is suggested that over 90% of all precipitation should be able to escape the infield areas. If puddles form despite your best efforts, a simple tool like the Puddle Sponge can be a very effective way to reduce puddling without displacing infield soil.
