Our specially designed 4″ knife-cut line of the pipe 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.
This item requires freight charges which will be added at checkout.
For larger orders of pipe (over 4 rolls) product and shipping discounts apply.
