Pet turf comes in two different drainage types—Fully Permeable and Hole-Punch.
Full permeable drainage is the best for turf meant to be installed in rainy areas. Turf with this drainage drains water at a rate of 250 inches per hour.
Hole punch drainage, on the other hand, works best for dry landscapes. Turf with this type of drainage has small holes that drain water at a rate of 50 inches per hour. A disadvantage of this type of drainage is that the pores are likely to get clogged, causing puddles of water to form on the turf.
