Our specially designed 4″ knife-cut is best for fine and sandy soils. The perforations resemble a knife slit, just big enough for a piece of paper to enter but allows for minimization of infiltration from fine soils or sand. This type of material is a more cost-effective alternative to using the filter sock material and is used in many agricultural applications.
