INSTALLING TURF FOR PETS
Installing turf for pets is generally the same as any normal turf installation. However, for even better drainage you can use a larger base rock, 3/4" minus rock otherwise known as road base, and it is still best to top dress with smaller 1" layer of 1/4" minus rock (paver base) or decomposed granite or similar in order to get a smooth and compacted surface.
Other recommendations are to use a pet-friendly turf infill like Envirofill or ZeoFill, or Biofill. These have antimicrobial properties to help control & neutralize pet urine odors. Also, treating problem areas with a Pet Odor Eliminator spray on a regular basis will help to control any other issues.
